DESIGN HIGHLIGHTS

  • UDC Series is a valve less type hammers designed for high performance at low operating air pressures

  • Suitable bits has a strong robust design without foot valve to withstand heavy duty application.

  • UDC Series Hammers maximizes energy output and reduces service requirements.

  • Wear Sleeve is not reversible.

  • All critical internal components are heat treated under strict control to maximize tool longevity.


EXCLUSIVE FEATURES 

  • A built-in choke facility allows the driller to adjust the volume of air through the hammer to optimize cuttings evacuation.

  • Unique internal mounting of liner eliminates the need for seating ring.

  • Fewer internal components minimize service requirements.

  • Multi-start threads on backhead and chuck ensure easy coupling / uncoupling of hammer.

  • Excellent for all types of drilling applications typically for water well drilling and geothermal applications.


APPLICATIONS 

          Water Well    Mining   • Construction    Quarry
