Trapezoidal Standard Thread Button Bits

Trapezoidal standard thread button bits (T-thread bits) are heavy-duty rock drilling tools designed for larger diameter holes and high-power top hammer drilling rigs.

Unlike the rounded profile of rope threads, these bits use a trapezoidal (T-shaped) thread profile with a steeper angle and a larger pitch, making them the industry standard for demanding environments like open-pit mining and large-scale bench drilling.Common sizes include T38, T45, T51, and T60, where the number refers to the thread's nominal diameter in millimeters.

Product Advantage

Superior Energy Transfer: The wide thread flanks and large pressure area ensure that impact energy from the hydraulic drifter is transmitted to the rock with minimal loss, resulting in faster penetration rates.


High Torque & Load Capacity: The robust trapezoidal shape handles significantly higher rotational torque and axial loads, preventing thread stripping or snapping during deep-hole drilling.


Extended Wear Life: The design provides a larger volume of material available for wear, allowing the threads to last longer under the extreme vibrations and heat of continuous heavy drilling.


Stable Connection: The steeper profile angle resists loosening from vibration better than rounded threads, maintaining a more secure lock even in fractured or abrasive ground.Reliability in Deep Holes: Specifically engineered for benching and long-hole drilling where accuracy and the ability to withstand extreme forces are non-negotiable.
