Tapered Button Bits

Tapered Button Bits

Tapered button bits are mainly applied to pneumatic rock drills and tapered drill rods to efficiently drill holes in projects like secondary crushing, rock bolt support and roadway excavation. It can be used in hard or extremely hard rock drilling.

Upgraded from standard drill bits, tapered drill bits have more dripping power and longer service life thanks to its alloy steel-made teeth and hot zinc-coating surface. It enjoys 5 to 6 times service life of flat drill bits with the same diameter and the advantages of saving work time, reducing work burden and accelerating the project process.
