Accupro 75337071 SNMG433 Carbide Turning Insert

Product Description

The ACCUPRO 75337071 is a carbide turning insert in the SNMG style, designed for use in CNC and manual lathe toolholders on steel and cast iron workpieces. It carries an ANSI insert code of SNMG433 and an ISO insert code of SNMG120412. The insert is CVD-coated in grade ACK10P, which delivers high wear resistance across both P-class steel and K-class cast iron applications. With 8 cutting edges and a neutral hand orientation, it offers a low per-edge cost and flexible toolholder compatibility. The corner radius is 1.20 mm (0.0472 inches) and the inscribed circle diameter is 0.5000 inches (12.70 mm).

This insert is suited for turning operations in production and job-shop environments where steel and cast iron are the primary workpiece materials. The ACK10P grade with CVD coating handles continuous and mildly interrupted cuts at moderate to high cutting speeds. It is compatible with SNMG-style toolholders that accept a square insert with a negative side clearance and a 0.2043-inch hole diameter. Machinists and CNC operators in general machining, automotive, and heavy equipment applications will find this insert a practical choice for high-volume turning passes.

Key Features

• CVD coating in grade ACK10P for high wear resistance on steel (P) and cast iron (K) workpiece materials
• 8 cutting edges per insert for extended tool life and reduced per-edge cost
• Neutral hand orientation for use on either side of the toolholder
• Corner radius of 1.20 mm (0.0472 inches) suits a wide range of finish and semi-finish turning operations
• Maximum depth of cut of 7.50 mm (0.2953 inches) handles both roughing and semi-finishing passes
• 909+ chip breaker geometry promotes effective chip control during turning
• Compatible with clamp, lever lock, pin, and screw insert holding methods

Compatibility

Designed for use in SNMG-style turning toolholders accepting a square negative-rake insert with a 0.5000-inch inscribed circle and a 0.2043-inch center hole. Suitable for P-class steel and K-class cast iron workpiece materials per ISO material classification.

Installation Notes

Insert installation and indexing should be performed by a qualified machinist or CNC setup technician. Power down and lock out the machine spindle before seating or indexing the insert. Confirm the toolholder pocket and clamping mechanism are free of chips and damage before securing the insert. Follow the toolholder manufacturer torque guidelines for the specific clamping method in use.
