Accupro 75260406 Turning Insert WNMG432 Carbide Cvd

Product Description

The ACCUPRO 75260406 is a WNMG-style carbide turning insert designed for precision external turning operations on CNC lathes and turning centers. Carrying the ANSI code WNMG432 and ISO code WNMG080402, this insert features a trigon 80-degree included angle with a negative side clearance and a 0.80 mm (0.0315 inch) corner radius. The substrate is carbide with a CVD coating and belongs to the CI series under manufacturer grade ACP35M. It is installed by machinists and CNC operators in production and job-shop turning environments.

This insert is suited for turning steel, stainless steel, and special or super alloys. Grade ACP35M is rated for high wear resistance to high toughness on steel (P-code), moderate wear resistance and toughness on stainless steel (M-code), and moderate wear resistance and toughness on special and super alloys (S-code). The WM+ chip breaker geometry supports a range of cutting conditions across these workpiece materials. The neutral hand orientation accommodates both right-hand and left-hand toolholders. Maximum depth of cut is 4.00 mm (0.1575 inches).

Key Features

• ANSI code WNMG432 and ISO code WNMG080402 for direct cross-reference and toolholder selection
• CVD-coated carbide substrate under manufacturer grade ACP35M for extended tool life on steel and stainless applications
• Trigon W-shape with 80-degree included angle provides strong cutting edge geometry
• Six cutting edges per insert for cost-effective indexing
• WM+ chip breaker designed for versatile chip control across P, M, and S workpiece material groups
• Compatible with clamp, lever lock, pin, and screw holding methods for broad toolholder fitment

Compatibility

Designed as an OEM-style replacement turning insert for WNMG432 and WNMG080402 toolholders using clamp, lever lock, pin, or screw holding methods. Verify inscribed circle, thickness, and hole diameter against your toolholder specification before ordering.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator with the machine powered down and the spindle locked before indexing or replacing the insert. Use the correct torque driver or wrench for the insert-holding screw or clamp to avoid cracking the carbide. Inspect the toolholder pocket and seating surface for chips or debris before seating the new insert. Never use a damaged or chipped pocket, as uneven seating will compromise edge life and dimensional accuracy.
