Q12-76 -T38 Retrac Button Bit 76mm T38 Thread Rock Drill Bit With Tungsten Carbide Buttons And Retrac Skirt Design

The Q12 - 76 -T38 Retrac Button Bit is a high performance threaded rock drilling bit specially engineered for fractured, loose and broken rock formations. Featuring a professional retrac skirt structure and premium tungsten carbide buttons, this 76mm T38 drill bit effectively solves common drilling points such as bit jamming, burying and hole deviation, delivering stable, efficient and long lasting drilling performance for underground long hole drilling, bench drilling and blasting projects.

As a professional China rock drilling tool manufacturer, HengLong Drill adopts high standard T6 / YK05 grade tungsten carbide and high-strength alloy steel as raw materials for all T38 retrac button bits. The matched material formula balances exceptional wear resistance and outstanding impact toughness, enabling the drill bit to withstand frequent percussion drilling in complex broken rock conditions without premature carbide wear or breakage.

Equipped with advanced integrated button fixing technology, our retrac drill bits feature uniform fastening force for carbide buttons. This optimized process effectively prevents button loosening and falling off during high-intensity drilling, greatly extending the overall service life of the drill bit and reducing frequent tool replacement costs for drilling operations.

Different from standard drill bits, the retrac design is the biggest highlight of this rock drilling bit. The optimized retrac skirt creates reasonable hole clearance during drilling, allowing smooth retraction of the drill string after operation. It significantly reduces the risk of bit sticking and burying in loose, fragmented rock layers, greatly improving construction safety and efficiency.

In terms of drilling efficiency, this retrac button bit minimizes impact energy loss during percussion transmission. The flat front face with dome carbide buttons concentrates drilling impact force on the rock surface accurately. Meanwhile, the structural design ensures excellent borehole perpendicularity and straightness, avoiding hole deviation caused by broken rock, which further boosts rock drilling speed and overall project productivity.

This Q12 - 76 -T38 retrac button bit is the core specification for underground long hole drilling and bench drilling operations. It is widely applicable to diverse engineering scenarios including :

Perfectly adapting to complex geological environments with loose and fractured rock mass.
