Kennametal 7093843 Cpmt Turning Insert Altin Carbide

Product Description

The KENNAMETAL 7093843 is a CPMT-style carbide turning insert designed for precision lathe and turning center operations. Featuring an 80-degree diamond (C-shape) insert geometry with an 11-degree relief angle, this insert delivers clean, consistent cuts on a wide range of workpiece materials. The AlTiN coating over a KCU10B carbide grade provides thermal resistance and wear protection during continuous and interrupted cutting. The corner radius measures 0.0157 inches (1/64 inch), making it well suited for finishing passes and light profiling where tight tolerances and surface finish quality are critical. Licensed machinists and CNC programmers specify this geometry for its balance of edge strength and clearance.

This insert is used in external turning, facing, and profiling operations on CNC lathes and manual turning centers. It suits both residential machine shop environments and high-production industrial settings. The neutral hand orientation allows flexible toolholder pairing. The LF chip breaker geometry is engineered for light finishing cuts, helping to manage chip evacuation at lower feed rates and depths of cut where fine surface finishes are required.

Key Features

• CPMT insert style with 80-degree diamond (C-shape) geometry for strong cutting edge engagement
• AlTiN coating on KCU10B carbide grade for elevated thermal and abrasion resistance
• 11-degree relief angle (clearance code P) for positive rake toolholder compatibility
• Corner radius of 0.0157 inches (1/64 inch) suited for finishing and light profiling
• LF chip breaker optimized for light finishing passes and controlled chip formation
• Neutral hand insert for broad toolholder compatibility
• 2 cutting edges per insert for extended usable life

Compatibility

Designed as a replacement-grade turning insert for CPMT-style toolholders accepting a size 2151 diamond insert with 3/32-inch thickness and 3/32-inch width. Verify toolholder pocket geometry, tolerance code M, and clearance code P requirements before installation.

Installation Notes

Installation and indexing of turning inserts should be performed by a qualified machinist or CNC technician with the machine spindle fully stopped and locked out per applicable machine safety procedures. Use the correct torque wrench and insert screw driver per the toolholder manufacturer specification to seat the insert without cracking the carbide substrate. Inspect the pocket seat and clamping components for wear or debris before seating a new insert. Follow your facility safety plan and applicable OSHA machining guidelines when handling sharp-edged carbide inserts.
