Kennametal 1162181 Ccgt Turning Insert K313 Uncoated

Product Description

The KENNAMETAL 1162181 is a solid carbide, uncoated turning insert in the CCGT style, designed for precision finishing operations on CNC lathes and turning centers. It carries the ANSI designation CCGT21505 and the ISO designation CCGT060202. The 80-degree diamond (rhombic) insert geometry delivers sharp, positive rake cutting action with a 15-degree rake angle and a honed cutting edge for clean, consistent surface finishes. The K313 grade provides high wear resistance suited to non-ferrous metals, stainless steel, cast iron, and superalloys. With a 0.0079-inch corner radius and a screw-on holding method, this insert seats repeatably in compatible toolholders for tight tolerances and minimal runout.

The 1162181 is intended for finishing passes in turning, facing, and boring applications. Its HP chip breaker geometry is optimized for light depths of cut up to 0.0492 inches (1.25 mm), making it well suited for close-tolerance work on non-ferrous metals, stainless steel, cast iron, and titanium or superalloy components. Machinists and CNC operators in production and job-shop environments use this insert where surface finish and dimensional accuracy are the primary concerns. The neutral hand orientation allows flexibility in tool setup for both OD turning and boring bar applications.

Key Features

• CCGT 80-degree diamond shape with positive rake and positive side clearance for low cutting forces
• K313 uncoated solid carbide grade — high wear resistance across stainless steel, cast iron, and non-ferrous applications
• HP chip breaker optimized for finishing operations with maximum depth of cut of 0.0492 inches (1.25 mm)
• Honed cutting edge for consistent surface finish and extended tool life on difficult materials
• Screw-on mounting method ensures secure, repeatable insert positioning
• Two cutting edges per insert; neutral hand orientation suits OD turning, facing, and boring

Compatibility

Designed as a screw-on replacement insert for CCGT-style toolholders conforming to ANSI size code 21505 and ISO size code 060202. Compatible with toolholders designed for a 0.25-inch inscribed circle CCGT insert. Suitable for turning, facing, and boring operations across material groups P, M, K, N, and S per ISO classification.

Installation Notes

Installation is performed by a qualified machinist or CNC toolroom technician. Always power down and lock out the machine spindle before seating or removing inserts. Use the manufacturer-recommended torque driver for the screw-on fastener to avoid cracking the carbide body or stripping the seating pocket. Inspect the toolholder pocket and shim for wear or debris before inserting — a contaminated seat will cause premature edge failure and dimensional drift.
