Accupro 75287003 Carbide Turning Insert WNMX431

Product Description

The ACCUPRO 75287003 is a CVD-coated carbide turning insert designed for external and internal turning operations on CNC lathes and turning centers. Conforming to ANSI code WNMX431 and ISO code WNMX080404, this insert features a W-Trigon 80-degree shape with a neutral hand orientation and a negative side clearance. The ACP15K grade combines high to moderate wear resistance with toughness, making it well suited for interrupted and continuous cuts in steel, stainless steel, and cast iron. The SWX+ chip breaker geometry assists in controlling chips across a broad range of cutting conditions. Each insert provides 6 cutting edges, extending tool life per unit.

This insert is intended for production turning applications in job shop and manufacturing environments. It is engineered to perform on steel (P), stainless steel (M), and cast iron (K) workpiece materials. The maximum depth of cut is 3.00 millimeters (0.1181 inches), and the 0.40 mm (0.0157 inch) corner radius suits medium finishing to light roughing passes. Machinists and CNC programmers working with standard WNMX-style toolholders using screw clamping will find this insert a direct fit.

Key Features

• CVD coating on ACP15K carbide grade for high wear resistance and toughness across steel, stainless steel, and cast iron
• W-Trigon 80-degree insert shape (WNMX) with 6 usable cutting edges per insert
• SWX+ chip breaker for consistent chip control over a range of feeds and depths
• Negative side clearance with screw holding method for secure, repeatable seating
• Corner radius of 0.40 mm (0.0157 inches) suitable for medium finishing and light roughing
• Maximum depth of cut of 3.00 mm (0.1181 inches)

Compatibility

Designed for use in WNMX-style screw-clamp toolholders accepting inserts conforming to ANSI code WNMX431 or ISO code WNMX080404. Verify inscribed circle, thickness, and hole diameter against toolholder specifications before installation.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Always index or replace inserts with the machine powered down and the spindle fully stopped. Use the correct torque wrench and insert screw specified by the toolholder manufacturer when securing the clamping screw — do not overtighten by hand. Inspect the toolholder pocket for wear or debris before seating a new insert to ensure proper contact and runout.
