Accupro 75356568 TNMG333 Carbide Turning Insert

Product Description

The ACCUPRO 75356568 is a TNMG-style carbide turning insert designed for general-purpose external and internal turning operations on CNC and manual lathes. It carries an ANSI code of TNMG333 and an ISO code of TNMG160412. The insert is manufactured from carbide substrate in the ACP25M grade and features a CVD coating for enhanced wear resistance across a broad range of cutting conditions. The triangular shape provides six usable cutting edges, and the neutral hand orientation suits a wide range of tool holders. Corner radius measures 0.0472 inches (1.20 mm), and maximum depth of cut reaches 0.1575 inches (4.00 mm).

This insert is suited for turning steel, stainless steel, and cast iron workpieces in both roughing and finishing passes. The WR+ chip breaker geometry is optimized for controlled chip formation during moderate to heavy material removal. Typical applications include shaft turning, facing, and contour work in job shop, production machining, and maintenance environments. The insert is installed by licensed machinists and CNC operators in metalworking facilities. It is sold individually but subject to a minimum order quantity of 10 units.

Key Features

• CVD coating on ACP25M carbide grade for high wear resistance across steel, stainless steel, and cast iron
• TNMG triangular shape delivers 6 cutting edges per insert, reducing per-edge tooling cost
• WR+ chip breaker geometry supports controlled chip evacuation during moderate to heavy cuts
• Neutral hand orientation is compatible with a wide range of TNMG-style tool holders
• Corner radius of 0.0472 inches (1.20 mm) balances surface finish quality with edge strength
• Compatible insert holding methods include clamp, lever lock, pin, and screw systems

Compatibility

Designed as an OEM-style replacement turning insert for TNMG333 (ISO TNMG160412) compatible tool holders accepting triangular negative-rake inserts with a 0.1512-inch hole diameter and 0.1874-inch insert thickness.

Installation Notes

Installation is performed by a qualified machinist or CNC operator. Power down and lock out the machine spindle before seating or indexing the insert. Ensure the tool holder pocket and clamping surfaces are clean and free of chips before installation. Verify that the selected holding method, whether clamp, lever lock, pin, or screw, is fully engaged and torqued per the tool holder manufacturer specifications before resuming cuts.
