China Supplier 3 inch down the hole rock drill bits with high air pressure hammer
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.
Detailed description: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.
