Kennametal 1870984 CCMT32505LF KC5010 Carbide Turning Insert

Product Description

The KENNAMETAL 1870984 is a solid carbide turning insert in the CCMT32505LF configuration, coated with TiAlN via a PVD process and graded KC5010. It features an 80-degree diamond (rhombic) shape, a 3/8-inch inscribed circle (0.3750 inches), and a corner radius of 0.0079 inches. The LF chip breaker geometry is optimized for finishing and light machining operations. With a neutral hand orientation, positive rake angle of 5 degrees, and positive side clearance, this insert is suited for high wear-resistance applications across steel, stainless steel, and cast iron workpieces. Licensed machinists and CNC turning specialists install this insert in screw-on toolholders.

This insert is intended for turning, facing, and boring operations on CNC lathes and manual turning centers. It is designed for finishing and light machining passes on steel, stainless steel, superalloys, and titanium workpiece materials (material codes P, M, K, N, S). The KC5010 grade delivers high to moderate wear-resistance and toughness across steel, stainless steel, and cast iron categories. The insert is sold individually (package quantity of 1) with a minimum order quantity of 5 units, making it appropriate for shop stock or toolcrib replenishment programs.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine before changing inserts. Use the appropriate torque wrench and insert screw to seat the insert firmly in the pocket — do not overtighten. Inspect the insert pocket and seating surface for chips or wear before installing a new cutting edge.
