Mill 1-18™ Carbide Milling Inserts
Mill 1-18 carbide milling inserts are engineered to add cutting versatility at larger axial depths of cut. Ideal for machining aluminum, steel, and other materials in profiling, slotting, ramping, helical interpolation, and plunging applications. The Mill 1-18 shoulder milling inserts feature two cutting edges and will help reduce cycle times and lower cutting forces. Insert geometries and grades are available for light-heavy-duty machining and can be found precision ground or pressed to size. Insert radii are available up to .250" (6.35mm).
