Accupro 75354720 Tcmt Carbide Turning Insert TCMT32.52

Product Description

The ACCUPRO 75354720 is a TCMT-style carbide turning insert designed for precision external turning operations on CNC and manual lathes. Identified by ANSI code TCMT32.52 and ISO code TCMT16T308, this insert features a triangular shape with a 60-degree included angle and a positive side clearance geometry. The CVD coating and ACK20P grade deliver high wear resistance when cutting steel (P) and cast iron (K) workpiece materials. With three usable cutting edges per insert, it delivers consistent performance across tool changes. It is installed and replaced by machinists, tooling technicians, and CNC operators working in general machining and production turning environments.

This insert is suited for turning steel and cast iron components in both light and moderate cutting conditions. The WM+ chip breaker geometry supports controlled chip evacuation during finishing and semi-finishing passes. A corner radius of 0.0315 inches (0.80 mm) provides a balance between surface finish quality and edge strength. The maximum depth of cut is 0.1181 inches (3.00 mm). It is appropriate for use in production shops, job shops, and maintenance machine operations where reliable tool life and repeatability are required.

Key Features

• TCMT triangular insert with 60-degree included angle and 3 cutting edges for extended tool life per insert
• CVD coating with ACK20P grade for high wear resistance on steel and cast iron
• WM+ chip breaker for controlled chip formation during finishing and semi-finishing cuts
• Positive side clearance geometry reduces cutting forces and heat buildup
• Screw-mount insert holding method ensures secure seating in compatible toolholders
• Corner radius of 0.0315 inches (0.80 mm) balances surface finish and cutting edge durability

Compatibility

Designed as a direct-fit replacement for TCMT32.52 (ANSI) and TCMT16T308 (ISO) style turning inserts. Compatible with TCMT-style screw-clamp toolholders accepting triangular inserts with a 0.1772-inch hole diameter and 0.1563-inch insert thickness. Verify toolholder specification against ANSI and ISO size codes before installation.

Installation Notes

Installation and replacement are performed by machinists or CNC tooling technicians. Always power down and lock out the machine spindle before indexing or replacing an insert. Use the correct torque tool specified by the toolholder manufacturer when tightening the clamp screw — do not overtighten, as this can crack the carbide insert. Inspect the insert pocket and clamp for wear or debris before seating a new insert to ensure proper contact and runout.
