Drill with Strength, Stability and PrecisionLearn more
Redesigned from the ground up to allow you to achieve higher performance, the new Perfomax ® drills will improve your application security, boost your productivity and achieve high tolerances with excellent surface finish. Multiple new design features combine to maximize chip evacuation, allowing you to increase your cutting data and benefit from significant cycle time reductions. The new tool also offers very high application security while providing a longer cutter body life.
New Flute Design
The new design of the front flute features a larger helix, smoother chip flute exit and larger center chip flute area. This results in shorter chips, which makes it easier to evacuate chips, reduces the risk of chip jamming and results in longer body tool life and better surface finish of the hole. This is especially true when machining long chipping materials.
Wave Pattern in the Flute
To further improve chip evacuation, the flutes now feature a wave pattern that generates an “anti-friction” surface. This minimizes the contact between the chip and the flute and leads to higher application security.
To enhance the drill body tool life, the front of the flute is now laser hardened. The high hardness of HRC 60 increases the tool life of the drill body up to 140% due to less risk of chip erosion.
More Radial Clearance of the Drill Body
Thanks to the radial clearance of the outside of the drill body, there is more room for the chips between the drill body and the hole surface. This leads to increased application security and lower tool cost by reducing the risk of chip jamming.
Polished Drill Body
The new Perfomax ® drill incorporates polished drill bodies to improve surface finish and reduce friction, leading to improved chip evacuation. Additionally, a polished drill body leaves a more eco-friendly footprint than a coated drill body.
New Pocket Design
An improved design creates a bigger radius at the bottom of the insert pocket and makes it more rigid than the previous version of Perfomax ®. The inserts in the periphery and center pocket also have more support thanks to a longer contact zone with the insert wall. This provides improved reliability and much better application security.
New Insert Combinations
One of the design changes implemented on the new drill point geometry is the introduction of new insert combinations for some diameters. More strength has been added to the drill body by leaving more material between the insert pockets
