Mill 4-15™ Shoulder Milling Inserts
For excellent surface quality and higher metal removal rates, the Mill 4-15 inserts are the perfect solution in 90-degree shoulder milling applications. These double-sided inserts provide up to 4 cutting edges and are engineered with a thick design supporting material near the cutting edge. These milling inserts offer superior wall and floor finish results even through multiple passes. The Mill 4-15 system eliminates that finishing pass with an additional tool, saving time and money. Mill 4-15 inserts can be applied to steel, stainless steels, ductile, cast irons, limited titanium material applications.
