Accupro 75392712 Carbide Turning Insert SCMT431

Product Description

The ACCUPRO 75392712 is a carbide turning insert designed for precision metal cutting on CNC and manual lathes. It carries the ANSI code SCMT431 and ISO code SCMT120404, identifying its square shape, 7-degree relief angle, and 0.40 mm (0.0157 inch) corner radius. The CVD coating and ACP25M grade deliver high wear resistance across a range of workpiece materials. Machinists and CNC operators install this insert into compatible SCMT-style toolholders for turning, facing, and profiling operations on steel, stainless steel, and cast iron.

This insert is suited for general turning applications in production and job-shop environments. It performs on steel (P-class), stainless steel (M-class), and cast iron (K-class) workpieces, covering a broad range of ISO material groups. The WM+ chip breaker geometry helps control chip formation across varying depths of cut up to 3.00 mm (0.1181 inch). It is a neutral-hand insert, fitting both left- and right-hand toolholder configurations. Typical users include CNC machinists, tool-and-die technicians, and production lathe operators.

Key Features

• CVD-coated ACP25M carbide grade for high wear resistance on steel, stainless steel, and cast iron
• Square SCMT insert shape with 90-degree included angle and positive side clearance
• 0.40 mm corner radius for balanced edge strength and surface finish
• WM+ chip breaker geometry supports chip control up to 3.00 mm maximum depth of cut
• 4 usable cutting edges per insert for extended tool economy
• Neutral hand — compatible with both left- and right-hand SCMT toolholders
• Screw-held insert design for secure, repeatable seating in the pocket

Compatibility

Designed as an OEM-style replacement insert for SCMT-style turning toolholders accepting ANSI SCMT431 or ISO SCMT120404 inserts with a screw-clamp holding method.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Always power down and lock out the machine spindle before changing inserts. Use the correct torque wrench and insert screw specified by the toolholder manufacturer — do not overtighten the clamping screw, as this can crack the carbide. Inspect the pocket seat and clamping screw for wear or debris before seating a new insert.
