Kennametal 7093274 Cnmg Turning Insert Altin Carbide

Product Description

The KENNAMETAL 7093274 is a CNMG-style indexable carbide turning insert designed for external and internal turning operations on CNC lathes and turning centers. Manufactured in the KCU10B grade with an AlTiN (aluminum titanium nitride) coating, this insert delivers thermal resistance and wear performance across a range of workpiece materials. The diamond-shaped insert body carries an 80-degree included angle and a neutral hand orientation, giving machinists consistent geometry for profiling and facing passes. With 8 cutting edges per insert, tool cost per edge is kept competitive in production environments. This insert is installed by CNC machinists and tooling specialists in job shop and production machining operations.

This insert is suited for medium turning and finishing applications where a 1.20mm corner radius provides a balance between edge strength and surface finish quality. The CNMG geometry with RP chip breaker designation is appropriate for continuous and lightly interrupted cuts. The 0.6250-inch inscribed circle and 0.2500-inch thickness conform to standard CNMG 543 sizing, making it compatible with toolholders built to that pocket specification. Applications include turning of ferrous and non-ferrous alloys where AlTiN coatings perform well under dry or minimum-quantity-lubrication conditions.

Key Features

• KCU10B carbide grade with AlTiN coating for thermal and wear resistance
• CNMG insert style with 80-degree diamond shape and neutral hand
• 1.20mm (3/64 inch) corner radius balances edge strength with surface finish
• 8 cutting edges per insert for efficient tooling cost management
• RP chip breaker geometry suited for medium turning and finishing passes
• Insert Size Code 543: 0.6250-inch inscribed circle, 0.2500-inch thickness

Compatibility

Designed as a drop-in replacement for CNMG 543 insert pockets in standard CNMG-compatible toolholders. Verify pocket and clamp style against the CNMG 543 footprint before installation.

Installation Notes

Installation is performed by qualified CNC machinists or tooling technicians. Ensure the machine spindle is fully stopped and the turret is indexed to a safe position before changing inserts. Seat the insert fully into the pocket and torque the clamping screw per the toolholder manufacturer specification using a calibrated torx or hex key. Inspect the pocket seating surface for chips or debris before installing a fresh edge to avoid premature edge failure.
