P-Geometry


The first choice for general applications, the P geometry is a strong and versatile solution that provides reliable operation in applications across a range of different materials.

M-Geometry

Utilising a free cutting drill point to minimise heat generation, the M geometry provides excellent performance in high temp alloys, titanium, titanium alloys and stainless steel. A 10% micrograin substrate, TiAlN coating and lowfriction TiN coating on the exchangeable head combine to increase toughness and reduce the potential of edge build up.

L-Geometry

The L geometry incorporates a flat geometry with a 140-degree centre point, achieving optimal chip control in ductile, long-chipping steels. Double land margins make the geometry a strong choice for demanding applications, such as angled exits. The 180° angle design makes the L geometry suitable for countersink operations for bolt heads. The diameter range covers the most common metric bolt sizes.
