Unique through coolant MMS drill for stainless steel

The MMS Drill utilises triangular-shaped coolant holes which have been shown to greatly improve coolant flow at the cutting point of the drill. Flow dynamic research has shown not just the benefits of extra volume, but also the way in which the coolant flows more efficiently from the hole.

This combination of extra flow and improved delivery to the cutting point is highly beneficial for continuous high performance when cutting "sticky" stainless steels. Curved edge geometry and optimised flute geometry, for effective chip curling and chip disposal, have also been incorporated into the design.

The MMS Drill is available in short and long flute types from 3 to 14.5 mm diameter in 0.1 mm increments, and also from 14.5 to 20 mm diameter in 0.5 mm increments. All other diameters can be made to order.

The drill also has a PVD coating, DP7020, based on Mitsubishi's proprietary Miracle Technology to give improved drilling productivity. The AlTiN base coating layer is supplemented with a TiN top layer for added wear resistance, which combats chip welding and material pick up on the flank and cutting edges.
