T45 89mm Retract Button Drill Bit | Retrac Threaded Rock Drilling Tool
Engineered for Broken & Variable Rock Formations
Retract button drill bits are specifically designed for fragmented, unstable, or geologically variable rock formations in rock drilling construction. Unlike standard bits, the retract bit features a distinctive skirt body with multiple grooves and a tapered tail profile. This design allows the bit to be easily retracted during drilling accidents or hole collapses, significantly reducing the risk of getting stuck downhole.
Beyond their anti-jamming design, retract drill bits offer the same flexibility as standard button bits. They can be customized with various thread types, face designs, and carbide button shapes to suit specific ground conditions.
As a professional retract drill bit supplier, we offer a full range of high-performance bits to meet your drilling needs.
KSQ Rock Drill Bits - Precision Engineered for Performance
At KSQ, the T45 threaded button bit is a key product, widely recognized as the most important size for benching and long-hole drilling underground.
Tungsten Carbide - T6 Grade
We select T6 grade tungsten carbide for its outstanding wear resistance and toughness. This carbide grade has proven itself as one of the best in the world and has been competing successfully with major international brands for many years.
Hot Insertion Technology
We use only high-quality steel suitable for hot insertion technology. This process secures the carbide buttons tightly within the bit body, significantly reducing the risk of button loss during drilling.
Button Shape Recommendation
To better resist highly abrasive rock formations, spherical button shapes are an excellent choice when high rotation speed is not a primary requirement.
