34mm 7 Degree Tapered Button Bit with Zin-Coated Inside Mining
Tools
Product Description:
Tapered button bit is mainly used with pneumatic rock drill and
tapered drill rod, and it conducts drilling operations through the
connection of the taper on the drill bit and drill rod. The tapered
button bits are suitable for hard rock drilling and are mainly used
in mine secondary crushing, bolting, drifting and other fields. As
an upgraded product of the chisel drill bits and cross drill bits,
the tapered button bits have good drilling effect and long service
life due to the tungsten carbide tips and the hot-plated skirts.
Conventional taper angles for tapered drill bits are 7°, 11° and
12°.
Features:
Tapered interface: The interface part of the drill bit is conical,
which allows the drill bit connect with drill rod firmly . It
greatly reduce looseness during the drilling process.
High strength materials: Since the drill bit needs to drill holes
in hard rock, it usually use high-strength alloy steel.
Moreover,heat-treated treatment of drill bits will improve wear
resistance and strength.

Applications:
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.
