FAQ

Q: What is the main application of the R32 76mm Reaming Button Bit?
A: It is designed for enlarging pre-drilled pilot holes in rock drilling, widely used in underground mining, tunneling, bench drilling, and quarrying to create larger diameter holes for blasting, pipe pushing, or anchoring.

Q: What rock conditions is this bit best suited for?
A: With high-grade tungsten carbide inserts and a heavy-duty forged alloy steel body, it performs well in medium to hard and abrasive rock formations. Spherical inserts offer maximum durability in hard rock, while ballistic inserts provide faster penetration in softer ground.

Q: Is the R32 thread compatible with standard top hammer drilling equipment?
A: Yes. The standard R32 thread profile ensures compatibility with conventional top hammer drill rods, shank adapters, and coupling sleeves across major machinery brands.
