Mining Carbide Rock Drill Bits 7 Degree 38mm Taper Button

Mining 7degree 38mm Taper Button Rock Drilling Bit

Description:

Different rock formation and rock drills require different taper angles. When drilling with high impact hydraulic rock drills in medium-hard to hard and abrasive rock formation, a wide taper angles is nomally used. Taper angles of 11° and 12° are normally used on modern drill rigs. For low impact rock drills and softer rock formation, a narrow taper angle of 7° is used. 7° can also be used if bit spinning is a problem when using 11° and 12° equipment.

Feature of taper button bit:

1.tapered button bits connect with tapered drill rod for drilling holes

2.Stale and mature welding technology ensure good quality of bits

3.Accurate dimension of taper degree perfectly matches the rods
