Kennametal 1162206 Turning Insert 55 Diamond K313 Carbide

Product Description

The KENNAMETAL 1162206 is a solid carbide, uncoated turning insert in a DCGT style with a 55-degree diamond (rhombic) shape. Manufactured to both ANSI (DCGT32505) and ISO (DCGT11T302) standards, this insert carries a K313 grade designation optimized for high wear-resistance across stainless steel, cast iron, aluminum, and non-ferrous materials. The insert features a positive rake angle of 15 degrees, a 7-degree relief angle, and a honed cutting edge style. With a corner radius of 0.0079 inches and an HP chip breaker geometry, it is engineered for finishing operations that demand tight tolerances and smooth surface finishes. Screw-on holding method provides secure clamping during high-precision cutting passes.

This insert is suited for finishing operations on non-ferrous metals, superalloys, titanium, stainless steel, and cast iron in CNC turning, facing, boring, back turning, and back boring applications. The neutral hand orientation makes it adaptable across both left- and right-hand toolholders. It is appropriate for light-to-moderate depth-of-cut passes with a maximum depth of cut of 0.0492 inches (1.25 mm). Machinists and CNC operators in production shops and tool rooms will find this insert well-suited for applications requiring consistent surface finish and dimensional accuracy in materials prone to built-up edge or work hardening.

Key Features

• DCGT 55-degree diamond shape with K313 grade carbide for high wear-resistance on stainless steel, cast iron, and non-ferrous materials
• HP chip breaker geometry designed for finishing operations with positive rake at 15 degrees
• Uncoated (bright) surface — no coating process applied, suitable for applications where coating adhesion or contamination is a concern
• Screw-on insert holding method for rigid, repeatable clamping in compatible toolholders
• Two cutting edges per insert for extended tool life per unit
• Meets ANSI and ISO dimensional standards for interchangeability across compliant toolholder systems

Compatibility

Designed for use in screw-on DCGT-style toolholders compatible with ANSI insert code DCGT32505 and ISO insert code DCGT11T302. Suitable for multi-use turning applications including turning, facing, boring, back turning, and back boring on non-ferrous metals, superalloys, titanium, stainless steel, and cast iron.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before seating or removing inserts. Use the correct torque driver and insert screw specified for the toolholder to avoid seat damage or screw failure — consult the toolholder manufacturer documentation for screw torque specifications. Inspect the insert seat and clamp screw for debris or wear before installing a new insert.
