Sandvik Coromant 5738042 Grooving Insert T-max Q-cut

Product Description

The SANDVIK COROMANT 5738042 is a solid carbide grooving insert designed for precision parting and grooving operations on CNC lathes and turning centers. Part of the T-Max Q-Cut series, this insert carries a TiAlN PVD coating applied via physical vapor deposition, which improves wear resistance and performance across a range of workpiece materials. The insert is neutral-handed with a positive rake geometry and a 5P chip breaker, delivering controlled chip formation during shallow grooving cuts. With a cutting width of 4 mm (0.1575 inches) and a maximum depth of cut of 1.7 mm (0.0669 inches), it suits tight-tolerance groove profiles in production turning environments. CNC machinists and tool crib technicians are the primary installers.

This insert is suited for grooving and parting applications on lathes handling small to medium-diameter workpieces. The T-Max Q-Cut series is common in both job shop and production turning environments where consistent groove geometry is required. The ISO designation is N151.2-400-40-5P 1125, and the insert size is 40. The neutral hand orientation accommodates radial grooving setups on standard tool holders compatible with the N151.2 insert style. This insert is packaged individually with a minimum order quantity of 10 units.

Key Features

• Solid carbide substrate with TiAlN PVD coating for extended tool life
• 4 mm cutting width with a maximum depth of cut of 1.7 mm
• 2 mm corner radius for consistent groove profile and edge strength
• Positive rake and 5P chip breaker geometry for controlled chip evacuation
• Neutral hand orientation compatible with N151.2-style T-Max Q-Cut holders
• Multi-use insert rated for repeated indexing within compatible tooling systems

Compatibility

Designed for use with T-Max Q-Cut toolholders accepting N151.2-style grooving inserts with insert seat size 40. ISO code N151.2-400-40-5P 1125 identifies the holder and seat compatibility. Specific model compatibility should be confirmed against the toolholder manufacturer specifications prior to installation.

Installation Notes

Installation is performed by qualified CNC machinists or toolroom technicians. The machine spindle must be fully stopped and the CNC program halted before indexing or replacing inserts. Use the appropriate Torx or hex key as specified by the toolholder manufacturer to seat the insert clamp; do not overtighten the clamping screw. Confirm insert seating and clearance before resuming cutting operations.
