Accupro 75525907 Tcmt Turning Insert Carbide Pvd

Product Description

The ACCUPRO 75525907 is a TCMT-style indexable carbide turning insert designed for precision metal-cutting operations on CNC and manual lathes. Built to ANSI code TCMT32.52 and ISO code TCMT16T308, this neutral-hand insert features a triangular shape with a 60-degree included angle and a 0.0315 inch (0.80 mm) corner radius. The ACM25P grade carbide substrate is finished with a PVD coating, delivering a balance of wear resistance and toughness suited to demanding turning applications. With three available cutting edges and a positive side clearance geometry, it maximizes tool life and cost-per-edge efficiency on production floors.

This insert is intended for turning steel, stainless steel, and special or super alloys, covering ISO material groups P, M, and S. The WM+ chip breaker geometry handles a range of cutting conditions from finishing to moderate roughing, with a maximum depth of cut of 0.1181 inch (3.00 mm). It is appropriate for use in screw-clamped toolholders accepting TCMT-series inserts. Typical users include CNC machinists and toolroom operators working in job shops, aerospace, and general manufacturing environments.

Key Features

• ANSI code TCMT32.52 and ISO code TCMT16T308 for broad toolholder compatibility
• ACM25P grade carbide with PVD coating for high wear resistance and toughness
• Triangular insert shape with 3 cutting edges reduces cost per edge
• WM+ chip breaker supports steel, stainless steel, and super alloy machining
• Positive side clearance and 7-degree relief angle reduce cutting forces
• Screw-clamp insert holding method for secure, repeatable seating

Compatibility

Designed as an OEM-style replacement for screw-clamped TCMT-series toolholders accepting ANSI TCMT32.52 or ISO TCMT16T308 inserts for turning steel, stainless steel, and special or super alloy workpieces.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torque wrench and manufacturer-specified clamping screw to seat the insert; over-tightening the clamping screw can crack the carbide substrate. Inspect the toolholder pocket and clamping screw for wear or damage before installing a new insert.
