Introduction to Low air pressure DTH drill bits

SDK is in the position to offer a very comprehensive range of DTH drill bits to match various conceivable drilling applications. DTH (Down the Hole) drill bits are widely used for large scale mine (open and underground), open quarry, water-well drilling, tunnel, geothermal drilling, subway engineering drilling, roads, power stations and other construction projects. Our drill bits adopt special heat treatment technology to enhance hardness, surface-compressed for fatigue resistance, all thus to extend the product life for maximum wear and performance in the toughest of drilling conditions.

The features

• Raw material: premium quality steel and YK 05 tungsten carbide.

• Working pressure: below 10bar/1 Mpa

• Low air pressure DTH drill bits diameter: 65mm-185 mm

• Carbide buttons shapes: ballistic and conical button

• Face type: flat and convex face

• Rock Application: medium-hard and homogeneous formation, soft rock and fissured rock formations
