Accupro 75469254 SCMT09T304 Carbide Turning Insert

Product Description

The ACCUPRO 75469254 is a SCMT-style square carbide turning insert designed for precision metal cutting on CNC lathes and turning centers. It carries the ISO designation SCMT09T304 and features a PVD coating in manufacturer grade ACM25P. The insert has a 7-degree relief angle, a 0.40 mm (0.0157 inch) corner radius, and four usable cutting edges, maximizing tool life per insert. With positive side clearance and a WM+ chip breaker geometry, it balances wear resistance and toughness across a broad range of workpiece materials. Licensed machinists and CNC operators install this insert on screw-clamped toolholders conforming to SCMT mounting standards.

This insert is suited for turning steel (P-class), stainless steel (M-class), and special or super alloys (S-class). The ACM25P grade provides high wear resistance for steel, moderate to high wear resistance for stainless steel, and moderate wear resistance with toughness for super alloys and nickel-based materials. It is appropriate for both roughing and finishing passes within its rated maximum depth of cut of 3.00 mm (0.1181 inch). Typical applications include shaft turning, facing, and contour turning on production and job-shop CNC equipment.

Key Features

• ISO designation SCMT09T304 with ANSI code SCMT32.51 for cross-reference compatibility
• PVD-coated ACM25P carbide grade for wear resistance across steel, stainless, and super alloys
• Four cutting edges per insert for extended tool economy
• WM+ chip breaker geometry for controlled chip formation across P, M, and S workpiece classes
• Positive side clearance (clearance code C, tolerance code M) for clean cutting action
• Screw-clamp insert holding method for secure, repeatable seating in compatible toolholders

Compatibility

Designed as an OEM-style replacement turning insert for screw-clamped SCMT-style toolholders accepting an inscribed circle of 0.3752 inch (9.53 mm) and a 7-degree relief angle. Verify toolholder pocket geometry against SCMT09T304 dimensional standards before installation.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before changing inserts. Use the correct torque wrench or insert key specified by the toolholder manufacturer when tightening the clamping screw - do not over-tighten, as this can fracture the carbide. Inspect the toolholder pocket for wear or debris before seating the new insert, and confirm the insert is fully seated before returning the machine to service.
