Kennametal 1163040 Turning Insert TP62 K68 Carbide 3/8 Ic

Product Description

The KENNAMETAL 1163040 is a solid carbide, uncoated turning insert in the TP62 geometry and K68 grade. It features a triangular (T) insert shape with a 60-degree included angle, a 3/8-inch inscribed circle, and a 1/32-inch corner radius. The screw-on holding method and positive rake with positive side clearance geometry support stable, predictable cutting performance. With a K68 uncoated carbide grade, this insert delivers high wear resistance suited to demanding turning applications on stainless steel, cast iron, aluminum, and other non-ferrous materials. It is installed by CNC machinists and turning center operators in production and job-shop environments.

This insert is suited for finish and semi-finish turning operations where wear resistance and edge sharpness are the primary requirements. The K68 grade is rated for high wear-resistance to moderate wear-resistance and toughness across workpiece material groups M (stainless steel), K (cast iron), N (aluminum and non-ferrous), and S (high-temperature alloys). The screw-on series mount is compatible with standard TP-style toolholders. Maximum depth of cut is 1.25 mm (0.0492 inches), making this insert appropriate for light to moderate material removal passes.

Key Features

• K68 uncoated solid carbide grade — high wear resistance for stainless steel, cast iron, aluminum, and non-ferrous materials
• Triangular insert shape with 60-degree included angle for versatile turning geometries
• Positive rake and positive side clearance for reduced cutting forces
• Screw-on holding method provides secure, repeatable seating in TP-style toolholders
• No chip breaker — bright uncoated surface for direct edge contact on finishing cuts
• Neutral hand orientation suits a broad range of turning setups

Compatibility

Designed for use in screw-on TP-style turning toolholders. ANSI insert code TP62; ISO insert code TP160308. Industry standard number CCGT432HP. ISO code C8FIX150605RRN. Compatible with workpiece material groups P, M, K, N, and S per ISO classification.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct screw-on torque driver recommended by the toolholder manufacturer — do not over-torque the clamping screw, as this can fracture the carbide insert. Inspect the toolholder pocket and seating surfaces for debris or wear before fitting a new insert.
