All our Bits and Impact bearing Hammer parts undergo shot peening for improvement in fatigue life and performance.

Customized Bits

We also manufacture special Bits required by the customers in special sizes.

DTH Hammers

Our Hammers are designed to be aggressive so that maximum drilling penetration can be achieved.

Features of each component in the hammer,

Wear sleeve has heavy wall thickness and specially heat treated to last internal and external wear.

Piston has been carefully designed to avoid stress contours and carry optimum weight to give more stroke. The use of superior material and precision heat treatment allows our piston to last long with minimum wear and tear.

Inner Cylinder They are precision ground and honed to ensure consistant stroke alignment which reduce internal hammer component wear and allows for unrestricted high volume air flow and enhanced hole cleaning capacity.

Air Distributor has been carefully studied & designed by our design department by using latest Pneumsoft Software.

Front Chuck is usually subjected to severe wear and tear as the pulverized cuttings cause extensive wear. Keeping this in mind our front chucks are coated with special grade materials which deposits on the wearing surface.

Interchangeability, Most of our components are interchangeable with the same range of hammers in National and International Market.

In-House Testing, We test all Hammers for their initial performance using our test Rig.
