Accupro 75242792 VCMT331 Carbide Turning Insert

Product Description

The ACCUPRO 75242792 is a VCMT-style carbide turning insert designed for precision metal removal on CNC and manual lathes. It carries the ANSI code VCMT331 and ISO code VCMT160404, featuring a 35-degree diamond (rhombic) insert shape with a 7-degree relief angle and positive side clearance. The CVD coating and ACP35M manufacturer grade deliver a balance of wear resistance and toughness suited to interrupted and continuous cuts on steel, stainless steel, and special or super alloys. The insert seats via screw-holding method and provides two usable cutting edges per insert, making it a cost-effective choice for production turning operations.

This insert is intended for turning applications on steel (P-class), stainless steel (M-class), and special and super alloys (S-class) workpiece materials. It fits standard VCMT-style toolholders and is appropriate for both roughing and finishing passes within its rated maximum depth of cut. Machinists working in job shops, production floors, and aerospace or oil-and-gas environments will find the WM+ chip breaker geometry effective at managing chip control across a range of feed rates and cutting depths. The 0.0315-inch corner radius supports a good surface finish while maintaining edge strength.

Key Features

• CVD-coated carbide substrate in ACP35M grade for high wear resistance and toughness across steel and stainless steel applications
• VCMT331 (ANSI) and VCMT160404 (ISO) insert codes for straightforward toolholder matching
• 35-degree diamond insert shape with 7-degree relief angle and positive side clearance for reduced cutting forces
• WM+ chip breaker geometry supports effective chip control on steel, stainless steel, and super alloys
• Two cutting edges per insert maximize usable life before replacement
• Screw-holding method provides secure, repeatable seating in compatible toolholders

Compatibility

Designed for use in VCMT-style screw-on turning toolholders accepting ANSI VCMT331 or ISO VCMT160404 inserts. Rated for primary workpiece material codes P (steel), M (stainless steel), and S (special and super alloys).

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Use the manufacturer-specified torque wrench or insert key to seat the clamping screw evenly; do not overtighten by hand. Inspect the insert pocket and seating surface for chips or debris before installing a new edge to ensure proper contact and dimensional accuracy.
