Cutters Mill 1-7™ • Inch

The Mill 1-7 high-performance shoulder mill cutters are a terrific choice for small component machining. Engineered specifically for multiple applications including facing, ramping, slotting, and plunging, the Mill 1-7 provides solutions for roughing and finishing operations. These small-diameter end mills are great for use in industries like energy, aerospace, and general engineering due to their small diameters. The Mill 1-7 shoulder mills are available in inch measurements, with cylindrical shanks, and an internal coolant supply. Inserts are available with two cutting edges and optimized with a straight 90° wall.
