Kennametal’s successful line of Mill 4 indexable milling cutters gains an important new member. Staying positive with a unique insert geometry and extremely accurate pocket positioning, the Mill 4-11 offers the free cutting action of a single-sided insert at the low cost per edge of a double-sided. The Mill 4-11 is also available in a variety of mounting options, with cutter diameters ranging from 16mm to 80 mm.

Designed for smaller machining centers, the Mill 4-11 accommodates 40-taper CAT and BT, HSK50, and similarly sized spindles. Due to its free cutting capabilities, it is ideal for successful metal removal in less-than-rigid setups and on light-duty machine tools, multi-taskers and live-tool lathes.

The Mill 4-11 enjoys the same strong insert design as its larger cousin, the Mill 4-15, but is
24% shorter and 34% narrower. With a 11mm maximum cut length, this addresses the needs of those job shops and manufacturers producing smaller parts and part features while still offering high metal removal rates and excellent tool life.

The Mill 4-11 is also easy to use. Each insert is securely locked in place with a single M3 screw, and marked with a series of dimples to indicate geometry and insert style. The cutter has uneven pocket spacing designed to break up machine harmonics and reduce chatter. Because of its complex insert geometry and positive placement in the pocket, it has an effective radial rake angle between 1° to 11°, depending on the cutter diameter, and an axial rake angle of 3°, this despite the Mill 4-11’s double-sided design.
