DHD Button Bits
What is our Down The Hole (DTH) Drilling Tools?
Down The Hole (DTH) Drilling Tools A wide range of products, including DTH Bits, DTH Hammer, DTH Drill Tube, ODEX & RC Drill Tools, Down The Hole (DTH) Drilling Spare Parts, Diamond Grinding Cups/Pins for Button Bits Sharpening. Down-the-hole rock tools (drilling tools) are rock drilling equipment which takes compressed air as power source to partially transfer impact power into drilling holes. An air distributing device in a top hammer controls a piston to move back and forth. An impact device arranged in the front of the top hammer transfers the impact powder to a down-the-hole bit to crush rocks. Our product range covers the most diverse applications in mining, natural resources exploration, water wells, quarries and civil works.
Why buy our down the hole (DTH) drilling bit?
1. Deliver maximum energy to drilling bit, fast drilling speed and low air consumption due to inner structure of HD series DTH hammer designed according to newest rock drilling theory.
2. Smooth performance and long service life of HD series DTH hammer due to high quality alloy steel materials and advanced processing technology adapted.
3. Low problem rate and easy to maintenance due to simple , reliable and easy assemble and disassemble inner structure of hammer.
4. Easy to depart bit from hammer due to multi—head thread connecting chuck and cylinder
of hammer.
5. Interchangeable with DTH bit and dill pipe manufactured by Atlas copco and Ingersoll-rand.
6. Our DTH drill bits are made from quality tungsten carbide steels and machined precisely to manufacture a perfect body. And then the buttons are heat-treated to the right hardness and each bit is finally fitted with required shape and sized buttons.
Our DTH ( Down The Hole) bits can be used for:
DTH ( Down The Hole) bits are widely used for open-pit mining, quarry, hydropower engineering, well drilling and excavation side column support, etc. We can supply DTH bits from 85mm to 305mm. The main products are:Similar or equal DHD, COP and SD series hammers, our DTH bits range from 85mm, 90mm, 95mm, 100mm, 105mm, 110mm, 115mm 120mm, 127mm, 133mm, 140mm, 146mm, 152mm, 165mm, 175mm, 190mm, 203mm, 216mm 254mm, 305mm, etc.
Roschen offers a full range of reverse circulation hammers with integrated bits designed to offer a cost effective, heavy-duty sampling system for obtaining a continuous, high quality geological sample. By maximizing the energy output and minimizing air consumption, Sandvik's products can assist in providing you with excellent production rates resulting in low cost per meter drilling.

Roschen range of high quality Reverse Circulation RC drill bits were specifically designed to work with our RC Hammers. Because of our drill bit sealing mechanism, sample contamination problems are not an issue.
Using our unique 12 spline shank design, these RC Bits provide outstanding performance and reliability.
Features:
1. Using higher grade carbides for longer life;
2. Minimizes hole erosion in fragile formations
3. Drills faster through soft formations with less blockages
4. Drills straighter through consolidated and unconsolidated formations
