Adriller – it's long-lasting
With Adriller you will get more meters drilled before first regrind, more meters drilled between regrinds,
And many more meters drilled at bit discard. This is long-lasting performance you can rely on.
Longer grinding intervals
Adriller taper button drill bits improve service life and reduce the need for constant regrinds.
The solution? New carbide button cutting geometries that offer maximum material on each button.
What's more, each button has gone through a special surface treatment to make it tougher and more durable.
For most rock formations we offer you up to 15 % more meters between regrinds.
Optimised face and body design: retrac bit
Everything in the design of the Adriller top hammer bit range is new.
The face is optimised for each type of rock. The flushing holes and flushing grooves are larger than
before to ensure efficient flush-out of ground rock.
Our new retrac bits feature a shorter, lighter retrac skirt allowing the impact energy to more effectively reach the rock, while still offering excellent bit steering
Harder, stronger steel body grade
The steel body grade for the Powerbit range is chosen with utmost care to ensure the right
hardness, strength and abrasion resistance.
Improved heat treatment gives at least 10 % better fatigue strength.
And, the stronger steel holds the buttons better, reducing the risk for pop-outs.
