Kennametal 5090854 VNMG332MS KCU10 Turning Insert

Product Description

The KENNAMETAL 5090854 is a solid carbide turning insert designated VNMG332MS in the KCU10 manufacturer grade, part of the KENLOC series. It carries a PVD-applied TiAlN coating and features a 35-degree included angle diamond shape with a neutral hand orientation. The insert measures 0.6538 inches in length with a 3/8-inch inscribed circle and a 1/32-inch corner radius. With four cutting edges, an MS chip breaker, and a honed cutting edge style, this insert is engineered for productive metal removal on demanding workpiece materials. It suits turning, facing, boring, back turning, and back boring operations.

This insert is designed for machining steel, stainless steel, superalloys, and titanium — ISO material codes P, M, and S. The KCU10 grade with PVD TiAlN coating delivers wear resistance and thermal stability well-suited to interrupted cuts and tough-to-machine alloys common in aerospace, energy, and general metalworking applications. A maximum depth of cut of 0.4354 inches supports both roughing and semi-finishing passes. CNC lathe operators and machining center programmers running high-productivity turning cells will find this insert a direct fit for VNMG-compatible toolholders.

Key Features

• PVD TiAlN coating for wear resistance on steel, stainless steel, and superalloys
• MS chip breaker geometry with 13-degree rake angle and honed cutting edge
• Four usable cutting edges per insert for extended tool economy
• Neutral hand orientation — compatible with standard VNMG toolholders
• Multi-use capability: turning, facing, boring, back turning, and back boring
• Meets ANSI and ISO standards; ISO designation VNMG160408MS

Compatibility

Designed for use in VNMG-style KENLOC-compatible toolholders. Suitable for turning, facing, boring, back turning, and back boring operations on steel, stainless steel, superalloys, and titanium workpieces. Insert holding method is clamp and pin. Verify toolholder pocket geometry matches VNMG insert style and 3/8-inch inscribed circle before installation.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine spindle before changing inserts. Use the correct torque wrench for the clamping screw — follow the toolholder manufacturer's seating procedure to avoid cracking the insert or damaging the pocket. Inspect the toolholder seat and locating pin for wear or damage before seating a new insert.
