6. 6 DTH PRODUCT CATALOGUE BIT FACE STYLES Concave Convex Flat This button is the most common shape utilized in DTH bits. This type of shape is the strongest and most resistant to breakage. The domed shape provides excellent penetration in medium rock, hard rock, and hard rock broken formations, in all types of drilling. Suitable for all soft and medium rock conditions including fractured and fissured rocks. Spherical (Dome) Ballistic Parabolic BUTTON SHAPES This face has been utilized in medium hard to hard drilling formation. Face design allows for increased body support for gauge carbide. There are two gauges and the inner gauge row helps to protect the outer row from excessive wear. The convex style tends to keep the drilling face intact longer by drilling with the two rows of the buttons on the convex face. This face style gives good hole pene - tration in medium to hard rock formations This is the common face style used in market. Cone shaped depression in the face has centering effect for straighter holes. It gives excellent penetration in soft to medium hard rock formation. This bit is very aggressive in drilling application and is suited best for hard to very hard rock and broken formation. Face slots help eliminate bit plugging in softer zones. More carbide to surface contact for better rock fracture. It is a simple and robust design well suited for hard to very hard rock formation. Normally this button is used in less hard consolidated drilling formations. This type of button is very aggressive and drills faster than domed. However, because the ballistic tip protrudes out farther than domed, the ballistic is prone to breakage if used in the wrong formations. Care should be taken when drilling with this type of button. Ballistic buttons yield high penetration rates and efficient rock breakage.

79. 79 DTH PRODUCT CATALOGUE • All rods should be cleaned before use to remove scrap (sometimes found in new rods), rust scales and debris. • Ensure that the air screen is in place and free from obstruction. • If hammer oil is only added at each rod change, care should be taken to ensure that an adequate supply of oil is maintained to the hammer at the recommended rate. Therefore, in hard formations, it may be necessary to add oil between rod changes. GENERAL INSTRUCTIONS As a guide to the most efficient weight the following procedure should be used. • Increase down-pressure until air pressure ceases to increase. • Note hydraulic feed pressure. • Reduce down the pressure until air pressure starts to decrease and note hydraulic feed pressure. • Operate between these two settings. Before shutting down at the end of each shift, we recommend the following procedures. • Flush hammer with air/water for few minutes and then turn off water injection. • Flush hammer with air/oil for a few minutes. This will coat the hammer parts preventing corrosion/rust. • Never leave the tool in a wet/muddy hole. Pull back from bottom as far as necessary to prevent the hammer sitting under water. • It is also good practice to pour at least half litre of oil down the drill at start-up of new shift. • If the hammer is removed from the drill rig for any reason, it is wise to pour some quantity of oil into it and • Pipe wrenches with flat jaws are not recommended as break-out tools. A more suitable tool would be a chain wrench, or similar type tool, which encircles the circumferences of cylinder (pipe wrenches with radial jaws approximating the curvature of the cylinder are also acceptable). • It is not recommended to use heat on any part of the hammer to assist break-ot,as this will affect the structure of the steel. • It is not recommended to subject the hammer to any external impact to assist break-out, as deformation of the cylinder and damage to threads may occur. • Break-out tool placement should not be over the cylinder thread area as this can lead to distortion and ultimate breakage. • Break-out tool placement on the bit shank is not recommended as this will damage the lower seal area. This will cause misalignment of the bit in the drive sub It is extremely important that an adequate supply of the correct type of rock drill oil is constantly fed to the ham - mer whilst it is operating. Failure to do so will quickly lead to excessive component wear and if the oil supply is cut off for any reason, the piston will quickly seize inside the wearsleeve, resulting in irreparable damage to both components. An airline lubrication system should be installed, preferable on the drill rig. The lubricator reservoir should be of sufficient capacity to supply the required volume of rock drill oil for a full shift. With this hammer, this might prove impractical, but the capacity should be sufficient for at least half a shift.This is equally important that the lubricator system must be adjustable and have a visual check to ensure the lubricator does not run out of oil. The amount of lubricating oil should be increased by 50% when drilling with water or foam. When new drill pipes are added to the drill string, it is recommended that a half pint (quarter of a litre) of rock drill oil is poured into the pipe to provide a good internal coating and helps prevent the hammer from running dry at any time. The grade of rock drill oil will be determined by the ambient temperature at the drilling site. If the ambient temperature is between 0 and 25 degree centigrade, then 30 grade oil should be used. If the ambient temperature is greater than 25 degree centigrade, use 50 grade oil. • As a rule of thumb, rotate the bit 2 revolutions per inch (25.4mm) of penetration. • Rotation too slow or too fast can cause premature bit failure. DTH HAMMERS MAINTENANCE GENERAL CARE RECOMMENDED WEIGHT ON THE BIT / ROTATION SPEEDS SHUT DOWN LUBRICATION HAMMER BREAKOUT block both ends. Provided the flushing, as outlined in steps one and two above have been carried out, the hammer should be stripped, cleaned and oiled before being stored.

81. 81 DTH PRODUCT CATALOGUE • There are two main areas to examine on a used piston:- • Check the body diameter for signs of pick-up and burning (both are signs of poor lubrication). Using a micrometer measure the diameter and refer to the quoted minimum size above. • Any light ‘Pick up’ marks can be removed using emery cloth, however if there are signs of overheating and cracking the piston should be replaced and the lubrication system examined. • Secondly, using a micrometer, measure the diameter of the bore at both ends of the piston andrefer to the maximum quoted sizes. • Examine the striking face. Some degree of distortion is acceptable providing there are no signs of cracking. If distortion has affected the chamfer and possibly distorted the foot valve bore diameter, this needs to be reformed on a lathe and the foot valve bore re-ground to its original diameter. Burrs and dents can be removed with an emery stone. INSPECTION • Either a micrometer or a vernier, measure the outer diameter of the wear sleeve. If it is below the minimum it must be replaced. The wear rate of the wear sleeve can be slowed by replacing the chuck before the wear area reaches the wear sleeve. • The bore of the wear sleeve should be periodically checked for any signs of ‘pick-up’. If a piston has broken within the wear sleeve it is imperative that the bore is honed to remove any burrs or ‘pick-up’. Failure to do so will result in ‘pick-up’ on the replaced piston and will lead to early failure of this component. • Inspect the O.D. for nicks, burrs and scoring. • Remove all minor irregularities with emery cloth. • Replace if necessary. AIR DISTRIBUTOR • The check valve should be smooth and free from abrasions. Replace if necessary. CHECK VALVE • Check make-up face, removing all nicks and marks. • Remove all burrs on the thread area with a fine file. • Inspect for damage such as cracks and deformations. • Replace if necessary. BACK HEAD O RINGS CHUCK DTH HAMMERS MAINTENANCE PISTON WEAR SLEEVE • Check for wear and cracks. • Always try and keep the chuck diameter should not be small than the wear sleeve this extends the service life of the wear sleeve.

33. 33 DTH PRODUCT CATALOGUE DTH SHANKS MAINTENANCE BUTTON BIT GRINDING When the button bit was first introduced, it was widely assumed that sharpening was unnecessary. Such an understanding was not unfortunate since the button bit is also subjected to wear and tear even if it may give, when compared to the conventional bits; a 300% increase in footage before sharpening becomes necessary. If re-sharpening is imperfect or if not done at the correct intervals, the button bit is likely to lose penetration speed and thereafter be subject to failure. While it was granted that in softer formations, an unsharpened button bit may continue to serve without carbide failure long after it ought to have been withdrawn from service it must also be appreciated that a similarly abused bit in a massive crystalline formation will very quickly fail. It is essential to remember that in hard rock, button bits are susceptible to failure from over drilling in the same way as any other bit. It is more economical to regrind too soon than to run the risk of damage by regrinding too late. GUAGE BUTTONS When the bit is withdrawn from the bore, it will be noticed that the gauge buttons are worn in such a way that the outermost wear faces are equidistant from the bit center. When regrinding the gauge buttons it is essential to maintain the equidistance. This is best achieved by grinding in such a way as to leave a very tiny unground portion on the extreme outer edge of each button. A perfect circle of the buttons can thus be maintained BUTTON GRINDING The object of grinding is to return the carbides to their original shape. This, in effect, means the removing of an equal depth of carbide from unworn areas of each insert. For the gauge buttons this means that most of the material must be ground from the in - ner side of the button hemisphere gradually extending around until only the slight unground outer portion is left as mentioned earlier. For the inner buttons the grinding must be done around the base of the hemisphere where it emerges from the steel bit body, since the wear generally occurs at the crown. AFTER REGRINDING RES TO RED SHAPE WEAR AFTER DRILLING REGROUND HEIGHT ORIGINAL HEIGHT OF STEE L ORIGINAL SHAPE OF CARBIDE STEEL GRINDING It will be noticed that after the button grinding is complete, there may remain an excess of steel between the buttons. This must be removed. More significantly, the chip-ways around the periphery of the bit must be restored to approximately to the original depth to facilitate free scavenging of cuttings from the bit face.in bits with central flushing, special attention must be paid to see that the free flow of exhaust air from the hammer is not in any way impeded by metal expansion around the flushing hole. Such an obstruction can seriously affect the efficiency of the hammer, and must be removed while grinding. ORIGINAL SHAPE OF CARBIDE WEAR AFTER DRILLIN G AFTER GRINDING REST ORED SHAPE • A reliable pencil type air grinder capable of approximately 25000rpm. • Spindle mounted grind stones, 1” (or 1.5”) x 1” (or 0.75”) x0.25” spindle, and suitable for high speeds. • One unused new bit similar to the one being grounded (this may be dispensed by experience), or a button guage. • Safety glasses and protective clothing. Pencil type air grinders consume very little air, and it is best if bit regrinding is done while drilling is in progress. Ringing a button bit does not require brute strength; rather it is an art and the lighter the touch, the better. With proper care the button bit will greatly reduce drilling costs. EQUIPMENT REQUIRED If a new bit is likely to fail due to material or manufacturing defects, it will normally do so in the initial half regrind life. The nature of such defects is dealt with later, but it is wise to withdraw and check any new bit early in life. Sometimes the gauge buttons may show slightly uneven wear or removal, i.e. while most show normal wear patterns the odd button may show excessive wear. This may be attributed to the slightly variation in setting of the gauge buttons. In such a vase, one or two buttons may be over ground while majority still requires no grinding. Prolonged initial drilling may thus lead to individual inset failure. WHEN TO REGRIND

34. 34 DTH PRODUCT CATALOGUE Only the slightest anti-taper is required at the periphery of a well-designed button bit. It is essential to n remember that the gauge buttons are inserted at an angle to the face buttons. As a consequence, if the anti - taper is excessive, the gauge button may fallout during work. It is rarely necessary to grind much from the periphery as the natural wear of the steel in work automatically reduces the bit body diameter. During the above mentioned operation, it is wise (until experience makes it necessary) to check the reground bit carefully against a new unused bit of same type, or by using a suitable gauge. This helps in seeing that the contours and gradients confirm as nearly as possible to the original. • See that the face buttons are so ground that they are equal in height and in same horizontal plane. • See that the gauge buttons, with respect to their outer periphery, are in the same radius. Each button should show at its outer edge a very slightly unground portion. • Check the buttons individually to see that they are roughly hemispherical in shape and not lob sided. • See that all chip ways are clear and adequate both on cutting face and ground the bit circumference. • Allow 3 degrees of anti-taper not more • See that the hammer exhaust passage within the bit is clear. • See that the reground bit counters confirm to the new unused bit. In general, a button-insert type of bit, compared to a cross or carset bit, will give two to four times the life between regrinds. It should be ground when the width of the flat developing on the outside edge of the gauge buttons is 0.25-0.33 times the diameter of the button insert itself. In soft ground this can be extended slightly but very hard rock the lesser figure should be taken as a guide. Although a well-grounded button bit will drill slightly faster than a similar cross bit, the main advantage of the button lies in its longer life between regrinds. LOSS OF BUTTONS • MANUFACTURING DEFECT This normally occurs only very early in life, usually before the first regrind. • BAD BIT GRINDING In this case the side supportive steel may have been removed when grinding. The hole becomes elongated and the button is lost. • UNDERFEEDING WHILE DRILLING IS IN PROGRESS In such a case, there is tendency for the hammer blows to drive the carbide inserts out of the body. It is, therefore important that adequate feed pressures be given at all times. • WEAR AND TEAR Frequently the first sign that bit has completed its life the “pop-out” of one or more gauge buttons, which means that they have common loose in the steel bit body. The correct use of rotation speed and feed pres sures will, however, go along way towards increasing bit life. BREAKAGE BUTTONS • FAULTY CARBIDE In button bits this is very rare. • BAD HANDLING Due to bad handling in transit carbides may chip.it is well protect carbides at all times when they are not in actual use. A wooden box with compartments for bit storage is recommended. ANTI TAPER FINISHING CHECK LIST GENERAL COMMENTS

35. 35 DTH PRODUCT CATALOGUE THE LOB SIDED INSERT OVER DRILLING / IMPROPER GRINDING These are the most usual causes of button breakage or buttons coming loose in the steel bit body. Normally it is the gauge buttons that are most seriously affected. Gauge buttons that break will usually be found to have sheared within the body itself. This is indicative of “pinch” action resulting from insufficient or improper grinding. The diagram clearly indicates why this occurs. As the apex of each gauge-carbide wears, the carbides are subjected to increased side thrust. Instead of hemisphere chipping a clear hole for the bit to follow, the sides of the bit and the sides of the carbide inserts forced into undersize bore. If this is not corrected by regrinding, the stresses finally become so severe that the inserts are either sheared or forced out of the bitbody. ORIGINAL SHAPE OF BUT TO N LO BSIDED WEAR P AT TERN EXTREME LO BSIDED PAT TERN DUE T O WEAR AND POOR GRINDING F ALSE APEX AX IS TRUE APEX AX IS Bad grinding has exactly the same effect. It is essential to maintain the hemispherical shape of the new carbide. Furthermore, the apex of the hemisphere must be true to the axis of the insert. If this is not observed while grinding the “lob-side inset” fault will develop in such a way that the apex of the gauge button insert hemispheres will start to shift towards the center point of the rock bit. The results are same as over drilling and broken or lost inserts will normally be results. THE FLAT HEMISPHERE OVER DRILLING / IMPROPER GRINDING The second type of insert type due to over drilling or bad is illustrated in the diagram. Here the true axis/apex relationship is retained but instead of a hemisphere the insert is allowed to develop a pronounced sub hemispherical contour. Due to the flattened nature of the insert hemisphere, the tendency is for the inserts to crush rather than chip the rock. The height of the apex of the insert above the stee bit body should be half the diameter of the insert. Check this point after grinding with a vernier gauge or an insert template. The results of following the flat hemisphere fault to develop will be put excessive shock loads on the equipment. Apart from a reduced penetration speed, this can result in insert shatter, failure of the steel bit body or hammer component failure. Proper grinding is the only answer. FL AT TRUE HEIGHT OF INSERT IS HALF INSERT DIAME TER CARBIDE INSERTS BREAKAGE Finally, carbide inserts will break quite spectacularly if in contact with steel or other inserts in the bore. After a failure, all carbide and steel must be removed from the bore before drilling is continued. Buttons bits have a large advantage over the conventional cross insert bit in that the failure of one button does not normally result in the breakage of other buttons and the bit may continue to be used satisfactorily even after inserts have failed. If a button breaks, grind away any projecting carbide, regrind the entire bit, and carry on. The WDS button bit is a perfect model of skilled craftsmanship. The finest materials and the most meticulous care go into making. At every stage of manufacture, the button bit is checked and rechecked to ensure the final product a maximum of durability, efficiency and profitability . WDS button bits are the products of years of painstaking research and the unending quest for perfection.
