Accupro 75258111 Turning Insert WNMG433 Carbide Cvd

Product Description

The ACCUPRO 75258111 is a WNMG-style carbide turning insert designed for external and internal turning operations on CNC lathes and turning centers. It carries ANSI insert code WNMG433 and ISO insert code WNMG080412, making it a direct reference for standard toolholder specifications. The insert features a W-shaped trigon body with an 80-degree included angle, a 0-degree relief angle, and a CVD coating applied over a carbide substrate. The ACP35M manufacturer grade and WM+ chip breaker geometry are engineered for steel, stainless steel, and special or super alloy workpiece materials. This insert is installed by CNC machinists and toolroom technicians in production and job-shop environments.

The ACCUPRO 75258111 is suited for general-purpose turning of steel (ISO P), stainless steel (ISO M), and special or super alloys (ISO S). The trigon insert shape and WM+ chip breaker support a range of cutting conditions from finishing to moderate roughing passes. With a maximum depth of cut of 0.1575 inches and a corner radius of 0.0472 inches, this insert is well matched to medium finishing and light roughing operations on bar stock and turned components. It is compatible with standard WNMG-style negative-rake toolholders using clamp, lever lock, pin, or screw holding methods.

Key Features

• CVD-coated carbide substrate in ACP35M grade for high wear resistance across steel and stainless applications
• W-shape trigon body with 80-degree included angle provides six usable cutting edges per insert
• WM+ chip breaker geometry balances chip control across steel, stainless steel, and super alloy workpieces
• Neutral hand orientation fits standard WNMG negative-rake toolholders without dedicated left or right-hand limitation
• Compatible with clamp, lever lock, pin, and screw insert holding methods for flexible toolholder selection
• Maximum depth of cut of 0.1575 inches supports medium finishing through light roughing passes

Compatibility

Designed for use in standard negative-rake WNMG-style turning toolholders accepting ANSI size code 433 or ISO size code 080412 inserts. Compatible holding methods include clamp, lever lock, pin, and screw styles. Workpiece material codes P, M, and S confirm suitability for steel, stainless steel, and special or super alloys.

Installation Notes

Installation is performed by a qualified CNC machinist or toolroom technician. Ensure the machine is in an E-stop state and the spindle is fully stopped before changing inserts. Seat the insert fully against the toolholder pocket locating surfaces before engaging the clamping mechanism to prevent insert rocking or edge chipping. Index to the next cutting edge only after the insert shows signs of wear or edge breakdown at the active cutting edge.
