The 89R32 Reaming Bit is designed for enlarging existing boreholes in rock drilling operations. Manufactured from high-grade alloy steel and fitted with tungsten carbide inserts, this bit ensures excellent wear resistance, high penetration rates, and long service life — even in the toughest rock formations.
It is specially engineered for use with R32 thread rods, providing precise alignment, strong coupling, and efficient energy transfer during drilling. The bit body is optimized for smooth chip evacuation, reducing jamming and heat buildup.
This reaming bit is widely used in tunneling, bench drilling, and mining operations, compatible with various hydraulic and pneumatic rock drills.
Made from premium alloy steel with carburizing heat treatment
High-quality carbide buttons for superior hardness and durability
Suitable for R32 threaded rod systems
Optimized design for high penetration and stable reaming performance
Available in multiple face designs — flat, domed, ballistic, or spherical buttons
Excellent flushing performance for both air and water systems
