Product Description

CIR100 Lower Pressure Down The Hole Hammer For Drilling Faster Rock Penetration

Our DTH bits and DTH hammer have various sizes and styles are available and applicable for drilling different kinds of rock formations.

Every bit, made from quality tungsten carbide steel, is precision machined to produce a perfect body. They are then heat-treated to the right hardness, facilitating excellent surface compression and fatigue resistance. Manufactured in-house, each bit is finally fitted with the required shape and sized buttons.


1. Designed specifically for drilling in holes where water is present. 

2. Production rates in wet hole conditions will be optimized due to the innovative technology used to design these hammers. 

3. The advanced design provides faster rock penetration using less air.

Hardened wear sleeves can be reversed or replaced giving the drill a new life. DOWN THE HOLE BIT A wide range of down the hole bits, these range from 3"to 20" in diameter and fit many hammers such as Ingersoll-Rand, Mission, Atlas Copco etc. For the most effective operation in various drilling conditions, we offer flat face, concave, drop centre head designs.
