Kennametal 1310735 Turning Insert CCGT3250LF KC5010 Carbide

Product Description

The KENNAMETAL 1310735 is a solid carbide turning insert with a CCGT3250LF geometry and KC5010 grade designation. It features a PVD-applied TiAlN coating that supports high wear resistance across a range of workpiece materials. The insert has an 80-degree diamond (rhombic) shape, a 3/8-inch inscribed circle, a 0.0039-inch corner radius, and an overall length of 9.67 mm (approximately 0.38 inches). With a positive rake angle of 5 degrees and a relief angle of 7 degrees, it is engineered for finishing and light machining operations. Licensed machinists and CNC tooling specialists are the primary end users for this insert type.

This insert is suited for turning, facing, and boring operations on steel, stainless steel, superalloys, titanium, cast iron, and aluminum. The LF chip breaker geometry is optimized for finishing and light machining passes, making it appropriate for close-tolerance work where surface finish and dimensional accuracy are critical. It is a screw-on style insert held by a central hole and is compatible with standard CCGT-style toolholders used in production turning applications, both CNC and manual. Maximum depth of cut is 1.25 mm (0.0492 inches).

Key Features

• KC5010 grade with PVD TiAlN coating delivers high wear resistance on steel, stainless steel, and cast iron
• 80-degree diamond insert shape provides two cutting edges with positive side clearance
• LF chip breaker geometry targets finishing and light machining applications
• Positive rake angle (5 degrees) reduces cutting forces during light-pass operations
• Screw-on holding method provides secure, repeatable insert indexing
• Conforms to ANSI insert code CCGT32502 and ISO insert code CCGT09T301

Compatibility

Designed as a screw-on CCGT-style turning insert for use in toolholders accepting CCGT 3/8-inch inscribed circle inserts per ANSI and ISO standard geometries. Compatible with multi-use turning, facing, and boring applications.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torque wrench and manufacturer-specified screw to secure the insert in the pocket — avoid over-torquing, which can crack the carbide substrate. Inspect the insert pocket and clamping screw for wear or debris before seating the new insert.
