Kennametal 1310800 Turning Insert TPGT3251HP KC5010 Carbide

Product Description

The KENNAMETAL 1310800 is a solid carbide turning insert in the TPGT3251HP geometry with KC5010 grade coating. It features a TiAlN PVD coating applied over a carbide substrate, delivering high wear resistance across a range of workpiece materials. The insert carries a 60-degree triangular shape, a 3/8-inch inscribed circle, and a 1/64-inch corner radius optimized for finishing operations. With a positive rake angle of 15 degrees and a honed cutting edge, it is engineered for light, precise cuts in steel, stainless steel, superalloys, and titanium. Licensed machinists and CNC lathe operators install this insert in screw-on style toolholders for turning, facing, and boring applications.

This insert is suited for finishing passes on CNC lathes and manual turning centers in both job shop and production environments. The HP chip breaker geometry targets finishing cuts with a maximum depth of cut of 0.0492 inches (1.25 mm), making it appropriate for close-tolerance work on steel and stainless components. It conforms to ANSI insert code TPGT3251 and ISO insert code TPGT16T304, allowing direct cross-reference to compatible toolholders designed for those standards. The insert is neutral-hand, so it functions in both right-hand and left-hand toolholder setups.

Key Features

• KC5010 grade with TiAlN PVD coating for high wear resistance on steel, stainless steel, and superalloys
• HP chip breaker geometry designed for finishing operations with a maximum depth of cut of 1.25 mm
• 60-degree triangle shape with 3 usable cutting edges per insert
• Positive rake angle (15 degrees) and honed cutting edge for clean, low-force cuts
• Screw-on holding method with positive side clearance (clearance code P, tolerance code G)
• Neutral hand — compatible with both right-hand and left-hand screw-on toolholders

Compatibility

Conforms to ANSI insert code TPGT3251 and ISO insert code TPGT16T304. Fits screw-on style toolholders designed for TPGT-series triangular inserts with a 3/8-inch inscribed circle. Suitable for turning, facing, and boring applications on steel, stainless steel, cast iron, aluminum, superalloys, and titanium workpieces.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. Power down and lock out the machine spindle before seating or indexing the insert. Use the correct torque driver for the screw-on clamp screw to avoid cracking the carbide substrate — consult the toolholder manufacturer specification for the appropriate fastener torque. Inspect the insert pocket and seating surface for chips or debris before installing a new edge.
