Sandvik Coromant 5737621 Grooving Insert 0.25 in T-max Q-cut

Product Description

The SANDVIK COROMANT 5737621 is a solid carbide grooving insert from the T-Max Q-Cut series, designed for precision grooving and parting operations on CNC lathes and turning centers. It features a neutral hand orientation, a 0.25 inch (6.35 mm) cutting width, and a maximum depth of cut of 0.095 inch (2.41 mm). The insert is coated via CVD with a TiCN/TiN finish, which improves wear resistance and extends tool life in steel and cast iron applications. Machinists and CNC operators install this insert into compatible T-Max Q-Cut toolholders for external grooving work.

This insert is suited for external grooving and cut-off operations in both production and job-shop turning environments. It is identified by ISO code N151.2-A250-50-4P 235 and carries a 4P chip breaker geometry with a positive rake angle. The insert seat size is 50, and the corner radius is 0.125 inch (3.18 mm). It is applicable across a maximum depth of cut range of 0.075 to 0.100 inch (2.00 to 3.00 mm), making it appropriate for moderate-depth grooving passes on ferrous and non-ferrous workpieces.

Key Features

Compatibility

Designed for use with SANDVIK COROMANT T-Max Q-Cut series toolholders accepting insert seat size 50. ISO code N151.2-A250-50-4P 235 identifies the exact insert geometry and grade for toolholder matching.

Installation Notes

Installation is performed by a qualified CNC machinist or toolroom technician. Shut down and lock out the machine spindle before seating or replacing the insert. Use the manufacturer-specified torx or hex key to secure the insert clamp — do not overtighten by feel alone; follow the toolholder manufacturer's clamping procedure. Inspect the insert pocket and seating surfaces for chips or debris before installing a new insert to ensure accurate seating and prevent premature edge failure.
