Accupro 75511576 Tcmt Carbide Turning Insert 0.0157 Cr

Product Description

The ACCUPRO 75511576 is a TCMT-style triangular carbide turning insert designed for precision external turning operations on CNC lathes and manual turning centers. Built to ANSI code TCMT1.81.51 and ISO code TCMT090204, this insert features a CVD coating in manufacturer grade ACK20P for high wear-resistance across steel and cast iron workpiece materials. The neutral-hand geometry, 7-degree relief angle, and 0.0157-inch corner radius support clean chip evacuation and consistent surface finish in moderate to high-feed turning passes. Licensed machinists and CNC operators use this insert as a direct screw-held replacement in standard TCMT toolholders.

This insert is suited for production turning of steel (P-class) and cast iron (K-class) workpieces in both light finishing and moderate roughing applications. The WM+ chip breaker geometry is optimized for work materials that require controlled chip breaking at varying depths of cut. Maximum depth of cut is 0.1181 inches, making it appropriate for semi-finish and finish turning passes in job shop and production-floor environments. The positive side clearance geometry reduces cutting forces and heat buildup, extending edge life on abrasive materials.

Key Features

• CVD-coated ACK20P carbide grade delivers high wear-resistance on steel and cast iron
• TCMT triangle shape provides 3 usable cutting edges per insert
• WM+ chip breaker geometry controls chips across a range of feed rates and depths of cut
• Positive side clearance reduces cutting forces and prolongs edge life
• Screw-held mounting method for secure, repeatable seating in standard TCMT toolholders
• Neutral hand orientation fits left-hand, right-hand, and axial-feed holder setups

Compatibility

Designed as an OEM-style replacement insert for standard TCMT-style screw-clamp turning toolholders accepting ANSI code TCMT1.81.51 or ISO code TCMT090204 inserts.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate Torx or hex key to seat the clamping screw to the toolholder manufacturers specified torque. Inspect the insert pocket and clamping screw for wear or damage before installing a new edge.
