Sandvik Coromant 5737674 Grooving Insert Solid Carbide

Product Description

The SANDVIK COROMANT 5737674 is a solid carbide grooving insert in the T-Max Q-Cut series, designed for precision parting and grooving operations on CNC lathes and turning centers. The insert carries an ISO code of N151.2-A250-50-5P 4225 and features a multilayer MT-CVD coating of TiCN, Al2O3, and TiN that extends tool life in demanding cut conditions. It delivers a 0.25 inch (6.35 mm) cutting width, a maximum depth of cut of 0.1142 inch (2.90 mm), and a 1/8 inch (3.18 mm) corner radius. Neutral hand orientation makes it suitable for straight-in grooving. Machinists and CNC operators working in precision machining environments install this insert as a direct replacement in compatible T-Max Q-Cut toolholders.

This insert is suited for grooving and parting applications in general machining, including ferrous and non-ferrous workpiece materials where a positive rake geometry and a 5P chip breaker improve chip control and surface finish. The insert size designation is 50, with a cutting height of 0.3191 inch (8.11 mm). The depth-of-cut operating range is 0.1000 to 0.1500 inch (2.00 to 3.00 mm), giving operators a defined working envelope for consistent, repeatable groove dimensions. It is sold individually but carries a minimum order quantity of 10 units.

Key Features

• Solid carbide substrate with MT-CVD multilayer TiCN, Al2O3, and TiN coating for extended wear resistance
• 0.25 inch (6.35 mm) cutting width with a maximum depth of cut of 0.1142 inch (2.90 mm)
• 1/8 inch (3.18 mm) corner radius and positive rake geometry for reduced cutting forces
• 5P chip breaker promotes controlled chip evacuation during grooving and parting
• Neutral hand orientation supports straight-in grooving without tool-path bias
• Multi-use tool designation allows use across a range of compatible groove widths within the insert seat size 50 system

Compatibility

Designed for use in SANDVIK COROMANT T-Max Q-Cut toolholders and blade systems accepting insert seat size 50. ISO code N151.2-A250-50-5P 4225 identifies the exact toolholder and seat interface required. Verify toolholder seat size and insert pocket dimensions before installation.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Power down and lock out the machine spindle before seating or removing inserts. Use the correct torx or hex key specified by the toolholder manufacturer to reach the recommended clamping torque range for the holder type — do not estimate clamping by feel alone. Inspect the insert pocket and clamping screw for wear or debris before seating a new insert to ensure proper contact and runout control.
