T40 90mm Self Drilling Rock Anchor Bit with Tungsten Carbide
Product Overview

The T40 90mm tungsten carbide self drilling anchor bit is a high-performance rock drilling tool engineered for rock bolting, underground mining, tunneling, slope stabilization, and coal mining applications. Featuring a standard T40 thread connection and 90mm diameter, this thread button anchor bit delivers exceptional rock breaking performance in medium to hard rock formations.

The self drilling anchor system combines drilling, anchoring, and grouting into a single, efficient operation, eliminating the need for pre-drilled holes and significantly reducing installation time. Manufactured from high-grade hot forged alloy steel with premium tungsten carbide inserts, our anchor drill bits ensure maximum wear resistance and extended service life.
