Sandvik Coromant 5738068 Grooving Insert Solid Carbide

Product Description

The SANDVIK COROMANT 5738068 is a solid carbide grooving insert designed for precision groove turning and parting operations on CNC lathes and turning centers. It carries the ISO designation N151.2-400-40-5G 1125 and belongs to the T-Max Q-Cut series, a line engineered for stable, repeatable grooving performance. The insert features a TiAlN PVD coating over a 1125-grade carbide substrate, providing wear resistance and thermal stability in demanding cutting environments. With a 0.1575-inch cutting width and a 7-degree rake angle, it delivers controlled chip formation on a range of workpiece materials. Professional machinists and toolroom technicians install this insert in compatible T-Max Q-Cut toolholders for production and maintenance turning work.

This insert is suited for grooving and parting applications on lathes equipped with T-Max Q-Cut compatible holders. The neutral hand orientation allows use on standard right-hand setups without requiring a mirrored holder. The 5G chip breaker geometry supports chip control during light to moderate depth grooving passes. Typical applications include external groove turning on ferrous and non-ferrous materials in job shop and production environments. The multi-use designation indicates the insert is suitable across multiple groove profile applications within its size range.

Compatibility

Designed as an OEM-style replacement insert for T-Max Q-Cut series toolholders accepting insert seat size 40 and ISO code N151.2-400-40-5G 1125. Specific holder compatibility should be verified against the manufacturer toolholder documentation before installation.

Installation Notes

This insert is installed and replaced by a qualified machinist or toolroom technician. Before changing inserts, power down and lock out the machine spindle in accordance with facility lockout/tagout procedures. Use the appropriate Torx or insert-clamping wrench specified for the T-Max Q-Cut toolholder; do not use improvised tools that may damage the insert seat or clamping screw. Inspect the insert pocket and clamping mechanism for wear or debris before seating the new insert.
