Domed/round button
Mainly used as side teeth for down-the-hole drill bits, suitable for highly abrasive and very hard rocks.
Parabolic /semi-ballistic button
It is mainly used as side teeth and middle teeth of down-the-hole drill bits, and is suitable for moderately abrasive and
relatively hard rocks.
Ballistic button
It is mainly used as the middle tooth of the down-the-hole drill bit, and is suitable for rocks with medium abrasiveness and
medium hardness. The side teeth can also be made when the rock is relatively soft.
Sharp buttons
It is mainly used as the middle tooth of the down-the-hole drill bit, and is suitable for soft rock formations with high drilling
speed and low tooth breakage rate.

Our factory 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, also called spline connected drill bit, 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.
