Tungsten Carbide Button Inserts for DTH & Top-Hammer Bits
Tungsten carbide button inserts — spherical, ballistic, conical and chisel — for DTH hammers, top-hammer bits and roller cones.
Buttons do the work at the rock face. The shape decides penetration and the grade decides whether the button wears or breaks first — both are matched to the rock and the drilling method.
Typical applications
- DTH (down-the-hole) hammer bits
- Top-hammer thread button bits
- Roller-cone bits and water-well drilling
What we supply
- Spherical, parabolic / ballistic, conical and chisel shapes
- Sizes to your drawing or bit design
Choosing the grade
Coarser-grained, tougher grades are typical for hard, abrasive rock and heavy impact; harder grades can suit softer formations where wear dominates. Tell us the rock type and hammer size.
Grade data (binder content, grain size, hardness, density, transverse rupture strength) is confirmed in writing for the grade we propose. How we choose grades →
