Kennametal 1162245 RCMT325 K313 Carbide Turning Insert

Product Description

The KENNAMETAL 1162245 is a solid carbide, uncoated round turning insert designed for precision metal removal on CNC and manual lathes. Manufactured to ANSI and ISO standards under the RCMT325 designation (ISO: RCMT097300), this screw-on insert features a full-radius round shape with a 3/8-inch inscribed circle, a 5/32-inch thickness, and a 3/16-inch corner radius. The K313 grade is an uncoated, bright-finish carbide formulated for high wear-resistance through moderate wear-resistance and toughness across multiple workpiece material categories. With 4 cutting edges and a positive rake geometry, it delivers efficient chip control in medium machining applications. Licensed HVAC techs, plumbers, and machinists working with tight tolerances will recognize this insert class as a shop-standard solution.

This insert is suited for turning, facing, and boring operations on non-ferrous metals, superalloys, titanium, stainless steel, cast iron, and aluminum. The K313 grade characteristics align it with ISO material groups P, M, K, N, and S, making it a versatile choice for job shops and production environments handling varied workpiece materials. The screw-on holding method provides positive insert registration in compatible toolholders, maintaining consistent edge presentation across the full cutting cycle.

Key Features

• Full-radius round insert shape (RCMT) with 4 indexable cutting edges for maximum edge utilization
• K313 uncoated solid carbide grade with high wear-resistance suited for stainless steel, cast iron, aluminum, and superalloys
• Positive rake and positive side clearance geometry for reduced cutting forces on non-ferrous and difficult materials
• Screw-on insert holding method for secure, repeatable seating in compatible toolholders
• Honed cutting edge style for improved edge stability and reduced micro-chipping
• Multi-use application: turning, facing, and boring from a single insert profile

Compatibility

Designed for use in screw-on style round insert toolholders accepting RCMT325 inserts with a 3/8-inch inscribed circle. Compatible with ISO and ANSI-standard RCMT toolholder bores. Suitable for turning, facing, and boring across ISO material groups P, M, K, N, and S per the K313 grade specification.

Installation Notes

Installation should be performed by qualified machinists or tooling technicians following the toolholder manufacturer's torque and seating specifications. Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate Torx or hex key for the clamping screw — never use damaged screws or worn drive tools, as improper seating will compromise edge geometry and surface finish. Inspect the toolholder pocket for chips or damage before seating the new insert.
