Mill 4-15™ Milling Cutters Inch
The Mill 4-15™ inch series of cutters is designed to achieve outstanding performance in surface quality as well as higher Material Removal Rates (MMR) in shoulder milling operations. Its unique design enables multiple passes (stepping down) and is applicable for use on a wide range of materials including steel, cast iron, stainless steel, and titanium. The mills have up to 15.5mm [.610”] maximum depth-of-cut and superior wall and surface finish capabilities. Along with an effective internal coolant feature, Mill 4-15 cutters are available in shell mill, screw-on, cylindrical, and Weldon shank options.
