Key features

QL shank design is specifically tuned for high frequency hammers, ensuring efficient energy transfer and reduced vibration fatigue.

Stop bit loss in fractured formations; unique gauge button protection maintains full diameter even in broken ground.

Field tests show 20% faster penetration in limestone and marble than standard flat face bits.

From dimension stone quarries to highway subgrades, one bit delivers reliable performance.

Double row gauge button design provides triple the wear resistance of single row designs, maintaining precise hole diameter.

Product Q&A

Q:Which QL hammers are compatible with this bit?

Our QL shank bits are compatible with all standard QL hammers including QL 5, QL 6, and QL 8 models.

Q:What is the advantage of the double row gauge button design?

It provides triple the wear resistance of single row designs, maintaining precise hole diameter and reducing rework in abrasive quarry formations.

Q:What is the optimal rotation speed for quarry applications?

We recommend 30-50 RPM for most quarry applications. Reduce speed to 20-35 RPM in highly fractured ground to prevent button damage.
