Diamond-ground carbide tip and PGM certification deliver accurate, stable holes. Hex shank allows efficient power transfer for rotary and impact drilling.
Clean, stable holes – with a diamond-ground carbide tip and PGM certification
Carbide tip uses diamond-ground cutting edges that resist wear and reduce walking during start-up. PGM certification confirms consistent hole diameter and positional accuracy.
Reliable, centred holes make fixing wall plugs and anchors straightforward. Less rework and fewer broken tiles during drilling.
One bit for many materials – thanks to universal drilling capability
Geometry and tip composition are engineered for combinations such as brick into tile or tile into concrete, allowing a single cutting edge to cope with changing layers.
Swapping between materials without changing bits saves time on multi-surface jobs. Handy for renovations where walls include different layers.
Secure power transfer for tough jobs – with a hex shank suited to impact use
Hex shank profile prevents slippage in the chuck and supports high torque transfer during rotary and impact drilling. Compatibility extends to cordless impact wrenches.
Confident drilling under load reduces bogging and bit wobble. Better suited to power tools used on construction sites and heavy DIY tasks.
