Sandvik Coromant 5736866 Grooving Insert T-max Q-cut

Product Description

The SANDVIK COROMANT 5736866 is a solid carbide grooving insert designed for precision grooving and parting operations on CNC lathes and turning centers. Part of the T-Max Q-Cut series, this insert features a multilayer MT-CVD coating of TiCN, Al2O3, and TiN, which provides wear resistance and thermal stability during continuous or interrupted cuts. The insert has a neutral hand orientation, a cutting width of 4.75 mm (0.187 inches), and a maximum depth of cut of 2.10 mm (0.083 inches). It carries ISO code N151.2-A187-40-5P 4225 and uses a 5P chip breaker geometry. Machinist and toolroom professionals install this insert in compatible T-Max Q-Cut toolholders for grooving steel and other materials requiring controlled chip formation.

This insert is suited for external grooving, parting, and face grooving applications on general-purpose turning machines in both job shop and production environments. The positive rake geometry and 5P chip breaker make it well matched to applications where consistent chip evacuation and dimensional accuracy are required. The insert size designation is 40, with an insert seat size of 40, fitting the corresponding T-Max Q-Cut toolholder bodies. The MT-CVD coating process delivers a harder, more adhesion-resistant surface than standard CVD, supporting longer tool life in steel and cast iron grooving applications.

Key Features

• Solid carbide substrate with MT-CVD multilayer TiCN, Al2O3, and TiN coating for extended wear resistance
• Cutting width of 4.75 mm (0.187 inches) for consistent groove sizing
• Maximum depth of cut of 2.10 mm (0.083 inches); effective range 2.00 to 3.00 mm (0.075 to 0.100 inches)
• Positive rake angle with 5P chip breaker geometry for controlled chip formation
• Neutral hand orientation for flexible setup in right- or left-hand toolholder configurations
• Corner radius of 2.37 mm (0.094 inches) for smooth groove floor finish

Compatibility

Designed for use in SANDVIK COROMANT T-Max Q-Cut toolholders accepting insert size 40 and seat size 40. ISO code N151.2-A187-40-5P 4225 identifies the exact toolholder interface and seating requirements. Verify toolholder compatibility against the manufacturer catalog number N151.2-A187-40-5P 4225 before ordering.

Installation Notes

This insert is installed by a machinist or toolroom technician following standard CNC lathe insert-change procedures. Power down and lock out the machine spindle before seating or removing any insert. Use the correct torx or hex key as specified by the toolholder manufacturer to achieve proper clamping torque — do not overtighten or substitute fasteners. Inspect the insert pocket and clamping screw for wear or debris before seating the new insert to ensure full surface contact and accurate positioning.
