The T45 Retrac Thread Button Bit is a premium-grade rock drilling tool engineered for hard rock mining, quarrying, tunneling, and construction applications. Featuring a standard T45 thread connection and retrac design, this bit delivers exceptional penetration rates, superior wear resistance, and reliable performance in demanding drilling conditions.
The retrac (retractable) design allows for easy bit retraction in broken, fractured, or collapsed ground conditions, significantly reducing downtime and improving overall drilling efficiency. Manufactured from high-grade forged alloy steel with premium tungsten carbide buttons, our T45 retrac button bit ensures maximum durability and extended service life.
