Accupro 75511527 Turning Insert VCMT331 Cvd Carbide

Product Description

The ACCUPRO 75511527 is a VCMT-style indexable turning insert designed for precision external turning operations on CNC and manual lathes. It features a 35-degree diamond (rhombic) insert shape, a CVD coating applied over a carbide substrate, and a neutral hand orientation. The ACP25M grade delivers high wear resistance across steel, stainless steel, and cast iron workpiece materials. The WSF+ chip breaker geometry controls chip flow during finishing and light-roughing passes. With two cutting edges and a screw-holding method, this insert suits high-volume production environments where consistent tool life and surface finish are required.

This insert is intended for turning steel (ISO P), stainless steel (ISO M), and cast iron (ISO K) workpieces. It is sold individually but must be ordered in multiples of 10. Typical applications include shaft turning, facing, and contouring passes where a sharp 35-degree nose geometry is needed to access tight part features. It seats in VCMT-compatible toolholders following ANSI and ISO standard dimensions and is installed by licensed machinists and CNC setup technicians in precision machining shops.

Key Features

• VCMT insert style with 35-degree diamond (rhombic) shape for access to tight workpiece geometry
• CVD coating on ACP25M carbide grade for high wear resistance in steel and stainless steel applications
• WSF+ chip breaker optimized for finishing and light-roughing passes
• Neutral hand orientation fits standard VCMT-compatible right- and left-hand toolholders
• Positive side clearance (clearance code C) reduces cutting forces and improves surface finish
• Two usable cutting edges per insert for extended tool life per unit cost

Compatibility

Designed to seat in VCMT-style toolholders conforming to ANSI insert code VCMT331 and ISO insert code VCMT160404. Compatible with toolholders that accept a screw-clamp holding method for VCMT inserts with a 0.1732-inch hole diameter.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and the tool is secured in the turret before indexing or replacing the insert. Use the correct torque driver or wrench for the clamping screw to avoid seat damage - consult the toolholder manufacturer specifications for the appropriate fastener torque. Inspect the insert pocket and seating surface for chips or wear before installing a new insert.
