Kennametal 1865953 Round Profiling Insert KC5010 Carbide

Product Description

The KENNAMETAL 1865953 is a round carbide profiling and turning insert in the K-LOCK series, designed for precision metal removal on CNC lathes and turning centers. It carries the RCMK35 insert style designation and is manufactured to ISO code RCMK090700. The insert features an AlTiN coating applied via PVD process, delivering elevated heat resistance and extended tool life across a broad range of workpiece materials. With a 3/8 inch inscribed circle, a 0.1875 inch corner radius, and a 13.23 mm thickness, it provides consistent chip geometry and four usable cutting edges per insert.

This insert is suited for profiling and turning operations in both roughing and finishing contexts across steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. The KC5010 grade covers material groups P10, P20, M10, M20, K05, K10, K15, K20, N10, N20, S10, S20, and H10, making it a versatile choice for shops that turn mixed-material jobs. The neutral hand orientation and positive rake angle of 7 degrees reduce cutting forces and support stable insert performance in typical OD profiling setups.

Key Features

• Round RCMK insert style with 360-degree included angle for full-profile turning
• KC5010 carbide grade with AlTiN PVD coating for heat and wear resistance
• Four cutting edges per insert for extended service life and lower cost per edge
• Positive rake angle (7 degrees) reduces cutting forces on the workpiece
• Compatible with K-LOCK clamping and pin holding systems
• Broad material grade coverage: P, M, K, N, S, and H workpiece categories

Compatibility

Designed for use in K-LOCK toolholders accepting RCMK35 or RCMK090700 standard inserts. Conforms to standards RCMK35 and RCMK090700. Suitable for turning and profiling applications across steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials.

Installation Notes

Installation is performed by qualified CNC machinists or toolroom technicians. Power down and lock out the machine spindle before seating or indexing inserts. Secure the insert using the appropriate K-LOCK clamp and pin per the toolholder manufacturer's specification. Inspect the insert pocket and seating surfaces for debris before each index to maintain accurate tool geometry.
