Accupro 75356964 TNMG332 Carbide Turning Insert

Product Description

The ACCUPRO 75356964 is a TNMG332 (ISO: TNMG160408) indexable carbide turning insert designed for general-purpose external and internal turning operations on CNC and manual lathes. Manufactured in the CI Series under grade ACP25M, it features a CVD coating that delivers high wear resistance across a range of cutting conditions. The triangular insert geometry provides 6 usable cutting edges, maximizing tooling value per insert. With a neutral hand orientation and a 0-degree relief angle (negative side clearance), this insert is suited for medium to heavy-duty cuts where edge stability is critical.

This insert is applicable across three primary workpiece material categories: steel (P), stainless steel (M), and cast iron (K), covering high wear-resistance to moderate toughness ranges in each category. It is intended for use by machinists and CNC operators in job shop, production, and maintenance machining environments. The WR+ chip breaker geometry supports controlled chip flow during turning, facing, and profiling passes. Maximum depth of cut is 4.00 mm (0.1575 inches), making it appropriate for medium-depth finishing and semi-finishing passes.

Key Features

• Grade ACP25M CVD-coated carbide for high wear resistance on steel, stainless steel, and cast iron
• TNMG triangular insert shape with 6 cutting edges for extended insert life
• Neutral hand orientation compatible with standard TNMG toolholders
• WR+ chip breaker for controlled chip management during turning and profiling
• 0-degree relief angle with negative side clearance for rigid, stable cutting
• Corner radius of 0.80 mm (0.0315 inches) suitable for semi-finishing and finishing operations

Compatibility

Compatible with TNMG332 toolholders accepting clamp, lever lock, pin, or screw insert holding methods. Fits any standard TNMG-style toolholder with a 0.1512-inch hole diameter and negative rake seat geometry.

Installation Notes

Installation should be performed by a qualified machinist with the machine powered off and the spindle fully locked before seating or indexing the insert. Use the appropriate torx or hex key for the specific toolholder clamping method — clamp, lever lock, pin, or screw — and ensure the insert seats flush against the pocket without rocking. Inspect the insert pocket for chips or debris before seating a new edge. Follow the machine tool manufacturer guidelines for recommended cutting parameters for the specific workpiece material and operation.
