Kennametal 2229656 CNMG432MS K313 Carbide Turning Insert

Product Description

The KENNAMETAL 2229656 is a solid carbide, uncoated turning insert in the CNMG432MS geometry, part of the KENLOC series. It features an 80-degree diamond shape with a neutral hand orientation, a 1/2 inch inscribed circle, and a 1/32 inch corner radius. The insert carries manufacturer grade K313, uses a negative rake angle of 13 degrees, and includes a honed cutting edge with an MS chip breaker. With four available cutting edges and compatibility with clamp and pin holding methods, it is suited for high-productivity turning, facing, and boring operations performed by machining professionals on CNC lathes and turning centers.

This insert is intended for use on non-ferrous metals, superalloys, and titanium, making it appropriate for aerospace, medical, and precision manufacturing applications where uncoated carbide grades C3 and C4 are specified. The CNMG432MS geometry supports turning, facing, and boring in both roughing and finishing passes within its maximum depth-of-cut envelope. It is sold individually per package with a minimum order quantity of 5 units.

Key Features

• 80-degree diamond insert shape (CNMG style) with neutral hand for flexible toolholder fitment
• Solid carbide, uncoated (bright finish) in grades C3 and C4 for non-ferrous and superalloy/titanium applications
• MS chip breaker geometry with honed cutting edge for controlled chip formation
• Negative rake angle (13 degrees) and 0-degree relief angle per CNMG standard geometry
• Four cutting edges per insert for extended tool life across multiple index positions
• Compatible with clamp and pin insert holding methods per KENLOC toolholder design
• Compliant with ANSI and ISO insert standards

Compatibility

Designed as an OEM-style replacement and standard-fit insert for KENLOC-series toolholders accepting CNMG432 geometry inserts. Suitable for multi-use applications including turning, facing, and boring. Primary workpiece material codes N (non-ferrous metals) and S (superalloys and titanium) apply.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians on CNC or manual turning equipment. Power down and de-energize the machine spindle before indexing or replacing inserts. Seat the insert fully against the toolholder pocket and torque the clamp or pin per the toolholder manufacturer specifications before resuming cuts. Inspect the insert pocket for debris or wear before seating a new edge.
