Accupro 75392464 Scmt Carbide Turning Insert SCMT433

Product Description

The ACCUPRO 75392464 is a square SCMT-style carbide turning insert designed for precision external turning operations on CNC and manual lathes. Built to ANSI code SCMT433 and ISO code SCMT120412, this insert features a CVD coating with manufacturer grade ACP25M, delivering high wear resistance across steel, stainless steel, and cast iron workpiece materials. The WM+ chip breaker geometry promotes controlled chip evacuation across a range of cutting parameters. With a corner radius of 0.0472 inches (1.20 mm) and a maximum depth of cut of 0.1181 inches (3.00 mm), it suits medium finishing and semi-finishing passes. The screw-lock holding method provides secure clamping in compatible SCMT toolholders.

This insert is suited for production turning environments where consistent tool life and dimensional repeatability are critical. It applies to general-purpose turning of low-alloy steels (P), austenitic and martensitic stainless steels (M), and gray or ductile cast irons (K). Typical users include CNC machinists and toolroom operators running production or job-shop turning operations. The neutral hand orientation allows use on standard right-hand and left-hand toolholder configurations. Four available cutting edges per insert reduce per-edge tooling cost in high-volume applications.

Key Features

• CVD coating with ACP25M grade for high wear resistance across P, M, and K workpiece material groups
• WM+ chip breaker geometry designed for steel and stainless steel turning applications
• Four cutting edges per insert maximize edge utilization and reduce tooling cost
• Positive side clearance reduces cutting forces and improves surface finish on medium cuts
• Screw-lock insert holding method for positive, repeatable seating in the toolholder pocket
• Square insert shape (S) with 90-degree included angle provides rigid, symmetric edge geometry

Compatibility

Designed as a direct-fit replacement for SCMT433 and SCMT120412 style insert seats in compatible screw-clamp SCMT toolholders. Confirm toolholder pocket tolerance and clearance code C compatibility before installation.

Installation Notes

Installation is performed by a qualified CNC machinist or toolroom technician. Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate Torx or hex key to secure the clamping screw to the toolholder manufacturer's specified seating procedure — do not overtighten. Inspect the toolholder pocket for chips or debris before seating a new cutting edge.
