The Retrac Button bit is widely recognized for its exceptional durability when drilling through medium-hard to hard abrasive rock formations with a compressive strength ranging from 200 Mpa to 260 Mpa. It is specifically designed with spherical tungsten carbide inserts, which have proven to be highly resistant against carbide fra true. This type of bit is highly recommended for drilling applications where hole deviation needs to be minimized. It is commonly used in drifting and tunneling operations, where precision and stability are critical. Furthermore, the bit face design of the Button bit is specifically tailored for medium-hard to hard abrasive rock formations. Its configuration ensures optimal performance and efficiency in these challenging drilling conditions. In conclusion, the Button bit stands out for its high wear resistance, making it a reliable choice for drilling through tough rock formations. Its spherical tungsten carbide inserts and bit face design contribute to its exceptional performance and durability.
When rock formations get tougher, drilling demands stronger, smarter solutions. That’s why professional miners and tunneling engineers around the world rely on T45 Retrac Button Bits—precision-engineered tools designed to deliver exceptional penetration, straight holes, and extended service life in even the most challenging ground conditions.
If you're serious about productivity, cost control, and drilling accuracy, T45 Retrac Button Bits are the high-performance solution you’ve been looking for.
T45 Retrac Button Bits are top hammer drill bits with a T45 thread connection, ideal for 76mm to 127mm hole diameters. The Retrac design features specially contoured shoulders that improve reaming and reduce hole deviation, making these bits ideal for fractured, abrasive, or irregular rock conditions.
Available in flat face, drop center, and concave designs with spherical or ballistic tungsten carbide buttons, T45 Retrac Button Bits are optimized for long-hole drilling, bench blasting, and underground tunneling.
Superior Drilling Stability
The retrac body helps maintain hole direction in broken or unstable rock, ensuring straighter drilling and easier rod retraction.
Faster Penetration Rates
With a balanced button layout and high-grade carbide tips, T45 Retrac Button Bits cut deeper and faster—reducing machine wear and fuel costs.
Longer Bit Life
Heat-treated alloy steel bodies and premium-grade carbides ensure that T45 Retrac Button Bits resist wear, fracturing, and deformation under extreme loads.
Consistent Energy Transfer
The T45 thread system ensures a strong connection with rods and shanks, minimizing energy loss and maximizing drilling impact.
