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.
