Sandvik Coromant 5738364 Grooving Insert 4mm T-max Q-cut

Product Description

The SANDVIK COROMANT 5738364 is a solid carbide grooving insert engineered for precision groove turning and parting operations on CNC lathes and turning centers. It carries the ISO designation N151.2-4008-40-5T 4225 and belongs to the T-Max Q-Cut series. The insert delivers a 4.00 mm cutting width with a maximum depth of cut of 1.80 mm and a corner radius of 0.80 mm. The multilayer MT-CVD coating stack — TiCN, Al2O3, and TiN — provides wear resistance and thermal stability during interrupted or continuous grooving cuts. Neutral hand orientation makes it suitable for straight-in grooving without directional toolholder preference. This insert is installed by machinists and CNC operators working in production and job-shop turning environments.

This insert is designed for external and face grooving applications on lathes equipped with T-Max Q-Cut compatible toolholders. The N151.2 insert style seats in size 40 insert seats. A positive rake geometry and the 5T chip breaker promote controlled chip formation, making this insert well suited for medium to finish passes in steel, stainless, and other machinable alloys. The multi-use designation indicates suitability across a range of grooving scenarios where consistent groove width and surface finish are required. It is sold individually with a minimum order quantity of 10 units per order.

Key Features

• 4.00 mm cutting width with 1.80 mm maximum depth of cut for precise groove profiling
• Solid carbide substrate in manufacturer grade 4225 for rigidity and edge stability
• MT-CVD multilayer TiCN, Al2O3, and TiN coating for extended tool life and thermal resistance
• 5T chip breaker geometry with positive rake for controlled chip evacuation
• 0.80 mm corner radius supports clean groove walls and reduces notching risk
• Neutral hand orientation compatible with standard straight-in grooving setups

Compatibility

Designed for use in T-Max Q-Cut series toolholders that accept N151.2 insert style in insert seat size 40. ISO designation N151.2-4008-40-5T 4225 identifies the correct seat and holder pairing.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator with the machine powered down and the spindle locked before changing inserts. Use the appropriate torx or clamp key specified by the toolholder manufacturer to seat the insert securely — do not overtighten by hand estimate alone. Confirm insert seating and clamp engagement before resuming cuts. Follow shop-standard lockout and tagout procedures in accordance with applicable machine safety requirements.
