Accupro 75332676 DNMG110408 Cvd Carbide Turning Insert

Product Description

The ACCUPRO 75332676 is a DNMG-style indexable turning insert designed for general-purpose external and internal turning operations on CNC lathes and turning centers. It features a 55-degree diamond (rhombic) insert shape, a CVD coating applied over a carbide substrate, and a neutral hand orientation. The insert carries ISO code DNMG110408 and ANSI code DNMG332. The WM+ chip breaker geometry supports a wide range of cutting conditions across steel, stainless steel, and cast iron workpiece materials. With four usable cutting edges per insert, it delivers strong cost-per-edge value for production turning environments.

This insert is suited for both roughing and finishing passes where consistent chip control and wear resistance are required. It is commonly used in job shop and production machining environments handling P-class steel, M-class stainless steel, and K-class cast iron components. The ACP25M grade designation places it in the CI series, targeting high wear resistance with sufficient toughness for interrupted cuts and variable material conditions. Machinists running moderate to high cutting speeds in steel or stainless applications will find this grade well-matched to those demands.

Key Features

• CVD-coated carbide substrate for extended tool life in steel, stainless steel, and cast iron
• 55-degree diamond (rhombic) insert shape provides a sharp, accessible cutting edge with good accessibility in tight profiles
• WM+ chip breaker geometry supports broad depth-of-cut and feed rate range
• Four cutting edges per insert maximize cost efficiency
• Negative side clearance with clamp, lever lock, pin, and screw holding compatibility
• Maximum depth of cut of 0.1575 inches (4.00 mm) suitable for medium stock removal

Compatibility

Designed as an OEM-style replacement turning insert for toolholders accepting DNMG-style inserts with negative rake geometry, M tolerance, and N clearance per ANSI and ISO insert standards.

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 appropriate torque wrench and manufacturer-specified fastener for the toolholder clamping method (clamp, lever lock, pin, or screw) to avoid seat damage or insert rocking. Never use a worn or damaged insert seat, as this will compromise edge repeatability and surface finish.
