R32 76mm Flat Face Standard Body Dome Button Bit for Mining Tunneling Quarrying

Product Specification

R32 76mm Flat Face Standard Body Dome Button Bit for Rock Drilling

The R32 76mm Flat Face Standard Body Dome Button Bit is a top hammer threaded button bit designed for efficient and stable drilling in rock formations.

With a 76mm drilling diameter and R32 threaded connection, this 3-inch rock drill bit is suitable for compatible R32 drilling systems. The flat face configuration provides a relatively broad contact area at the hole bottom, while the dome-shaped tungsten carbide buttons are designed to withstand repeated percussive impact during rock drilling.

The standard body provides a conventional bit profile for general-purpose top hammer drilling. This bit can be used for underground mining, tunneling, quarrying, construction drilling, rock excavation, and general top hammer drilling where an R32 threaded 76mm bit is required.

FAQ

Q: What is an R32 76mm Flat Face Standard Body Dome Button Bit?
A: It is a top hammer threaded rock drill bit with a 76mm diameter, R32 thread, flat face and dome-shaped tungsten carbide buttons, designed for mining, tunneling, quarrying and general rock drilling.

Q: What is the difference between flat face and dome face?
A: A flat face has a relatively broad, flat bit face, while a dome face has a more rounded/convex profile. The appropriate face design depends on rock formation, drilling conditions and the desired balance between penetration, hole straightness and button support.

Q: What drill rod is compatible with an R32 76mm button bit?
A: The bit is designed to connect with a compatible R32 threaded drill rod and R32 shank adapter. The complete drilling string should be selected according to the rock drill, drilling rig and operating conditions.
