Description
JDM SERIES
JDM35MD / JDM35DH (3.5”)
JDM45DH (4.5”)
JDM55QL(5.0”)
JDM60QL(6.0”)
JDM80QL (8.0”)
JDM10SD (10.0”)
DESIGN HIGHLIGHTS
JDM 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.
JDM 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.
Robust piston design for optimum strength and performance
Fitted with a reversible cylinder to maximize operating life.
Multi-start threads on backhead and chuck ensure easy coupling / uncoupling of hammer.
Excellent for all types of drilling applications including residential
geothermal, production quarry drilling, seismic drilling and small construction drilling.
APPLICATIONS:
• Water Well • Mining • Construction • Quarry
