Product Construction

The 45R32 - Q7 top hammer button bit consists of two core functional assemblies : alloy steel skirt body and hard tungsten carbide buttons.

The bottom threaded section of the steel skirt locks tightly with R32 drill rods, transmitting percussion and rotary power from pneumatic/hydraulic rock drills to the bit face
Embedded YK05 carbide buttons bear direct impact force to crush, crack and strip rock formations, realizing efficient hole drilling

HENGLONGDrill develops a full lineup of threaded drill bits covering all mainstream top hammer thread standards to match diverse drilling rig equipment: R25, R28, SR28, R32, SR32, R38, SR38, T38, T45, T51, GT60, T-WIZ60 and more. Besides threaded button bits, our product portfolio also includes chisel drill bits, cross bits, DTH hammer bits and matched drill rods, shank adapters for one stop drilling tool sourcing.

Key Advantages

Premium YK05 Tungsten Carbide for Long Service Life

Equipped with ZCC YK05 grade tungsten carbide inserts, this material balances outstanding wear resistance and impact toughness perfectly, capable of enduring frequent heavy percussion without easy cracking or chipping.

Hot Insertion Process Prevents Button Falling Off

Advanced manufacturing process locks carbide buttons into the bit body with ultra tight bonding force, drastically lowering the risk of button detachment during continuous high load drilling.

Spherical Carbide Buttons for Abrasive Rock Drilling

Spherical ball carbide buttons serve as the optimal configuration for low-speed stable drilling in highly abrasive rock layers, distributing impact pressure evenly to reduce surface abrasion.

Optimized Dual Flushing Hole Design

1 front central flushing hole plus 1 side flushing channel forms a dual cooling debris removal system, accelerating flow to wash away rock cuttings and avoid bit face overheating.

Main Application Scenarios

The 45R32 - Q7 threaded button bit is the dominant specification for underground drifting, tunnel excavation and mine development drilling works. It fits small to medium sized top hammer drill rigs, widely applied in these engineering sectors :

Underground metal mine drifting production hole drilling
Highway / railway tunnel preliminary blasting hole drilling
Hydropower underground cavern excavation
Urban underground pipe gallery construction
Quarry pre split blasting drilling

Thanks to its universal standard skirt structure and adaptable button layout, contractors can use this single drill bit model to handle soft, medium hard and slightly abrasive rock strata without frequent tool switching.
