MHS drills - Dedicated design for high speed deep hole drilling of hardened steels

Specially developed for hardened steel, ultra high performance carbide drills for standard and deep holes up to l/d 30. Ideal for eliminating a pre-drilling process because a high quality finished hole can be made directly in the hardened mould material.

MHS drills have a specially designed "wave" type cutting edge and point geometry for improved penetration and a decrease in tool load, especially for extra deep hole applications. The other important faeature is the 25º helix angle of the flute, designed for ultra efficient chip clearance and extra strength compared to conventional flutes. Additionally, a new double margin flute is the latest feature to provide the highest accuracy, smooth chip evacuation and smooth surface finishes necessary for ejector pins.

Due to the unique design and the wave type cutting edge geometry and the all important through coolant holes, MPS is capable of incredible cutting performances even at the highest speeds and feeds.

The use of the highly wear and oxidation resistant Miracle Coating achieves long tool life at extreme feed rates or during high temperature conditions experienced during deep drilling operations.

This range of drills achieves state of the art performance and hole precision even under the toughest cutting conditions.

Available from Ø3.0mm – Ø12,0mm, maximum flute-length is 300mm up to diameter
