Sandvik Coromant 5753844 TNMG322-QM 235 Turning Insert

Product Description

The SANDVIK COROMANT 5753844 is a TNMG322-QM 235 grade solid carbide turning insert from the T-Max P series, designed for precision metal cutting on CNC lathes and turning centers. The insert features a CVD-applied dual-layer TiCN and TiN coating that resists wear and extends tool life in demanding cutting applications. With a 60-degree triangular shape, a 3/8-inch inscribed circle, and a 1/32-inch corner radius, it delivers consistent chip control through the QM chip breaker geometry. It is intended for installation by machinists and tooling technicians working in production turning environments.

This insert is suited for turning steel as its primary workpiece material and stainless steel as a secondary application. The neutral hand orientation makes it compatible with standard right-hand toolholders using clamp or pin holding methods. The QM chip breaker geometry is optimized for medium cutting conditions where controlled chip evacuation is critical. The ISO designation for this insert is TNMG 16 03 08-QM 235, which can be used to cross-reference compatible toolholder systems and confirm fitment in existing setups.

Key Features

• CVD-coated with TiCN and TiN layers for improved wear resistance and thermal stability
• QM chip breaker geometry designed for controlled chip evacuation in medium turning applications
• 6 cutting edges per insert for extended service life and lower cost per edge
• Neutral hand orientation compatible with standard right-hand turning toolholders
• 60-degree triangular insert shape with N clearance and M tolerance classification
• Clamp and pin holding method provides secure seating in T-Max P series toolholders

Compatibility

Designed for use with T-Max P series toolholders accepting TNMG-style inserts. ISO designation TNMG 16 03 08-QM 235 can be used to verify toolholder compatibility. Rated for primary use on steel workpieces and secondary use on stainless steel.

Installation Notes

Installation is performed by a qualified machinist or tooling technician. Power down and lock out the machine spindle before seating or removing the insert. Use the appropriate torque wrench and clamp screw specified by the toolholder manufacturer - do not overtighten, as this can crack the carbide substrate. Inspect the insert pocket for chips or debris before seating to ensure proper contact and avoid premature edge failure.
