DESIGN HIGHLIGHTS

  • JDC 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.

  • JDC 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 maxim tool longevity.


EXCLUSIVE FEATURES
