HengLong T45 Threaded Button Bit With 45mm Pitch Thread And YK05 Tungsten Carbide Buttons For Heavy Duty Rock Drilling
HengLong T45 threaded rock bit adopts industry standard 45mm pitch thread, built for heavy duty top hammer drill rigs deployed in open pit mining, quarry aggregate production and underground hard rock drifting work.
Each bit blank is forged from premium 45CrNiMoVa alloy steel and fitted with robust YK05 tungsten carbide buttons, retaining stable geometry under continuous cyclic percussive loads.
Superior Material Performance
Unlike generic aftermarket rock drill bits, our bit body balances high surface hardness and outstanding impact toughness. Through tailored heat treatment procedures, we achieve ideal trade-offs between exterior hardness and inner core ductility.
Even when working against abrasive granite or heavily fractured ground conditions, the bit body absorbs heavy shock without crack propagation.
YK05 Carbide Button Technology
YK05 carbide buttons are purpose-engineered for extremely hard, high-abrasivity rock strata. Boasting superior lateral breaking strength, these carbide inserts resist chipping and fracture under repeated impact force.
This practical feature extends re-grinding intervals, sustains consistent drilling footage, and delivers steady penetration rate throughout the bit's entire service lifecycle.
Reinforced Ribbed Skirt Design
The reinforced ribbed skirt profile is highly recommended for borehole collapse prone ground. While pulling back the drill string, outward expanding rib structures clear fallen rock debris smoothly and help retract tools without jamming.
Without such anti-stuck protection, operators risk tool loss or catastrophic drill rod breakage caused by stuck bits.
Precision Manufacturing
Every HengLong T45 rock bit features CNC high precision machined threads with tight manufacturing tolerances. It directly mates with standard T45 MF extension drill rods and T45 coupling sleeves.
Tight thread coupling eliminates energy dissipation from loose joints, transferring full percussive power onto rock cutting surfaces to maximize drilling output.
