Sandvik Coromant 5737372 Cutoff Insert Carbide 4mm

Product Description

The SANDVIK COROMANT 5737372 is a solid carbide cutoff insert designed for parting and grooving operations on CNC lathes and turning centers. It carries the manufacturer designation N151.2-400-5F 1125 and belongs to the T-Max Q-Cut series. The insert features a 4.00 mm cutting width, a TiAlN coating applied via PVD process, and a 5F chipbreaker geometry. The 1125 grade is suited for a range of workpiece materials where wear resistance and edge stability are priorities. A neutral lead angle and 7-degree relief angle support consistent chip formation and tool life in production turning environments. Licensed machinists and CNC operators are the primary installers of this consumable tooling item.

This insert is applied in parting-off and grooving operations on turning machines where the T-Max Q-Cut clamping system is in use. The 4.00 mm cutting width and 0.20 mm corner radius make it appropriate for moderate-depth grooving and cutoff work on bar stock and tubular workpieces. The neutral hand orientation allows use in standard right-hand toolholders configured for the N151.2 insert style. It is a single-edge insert sold individually with a minimum order quantity of 10 units per order.

Compatibility

Designed as a direct-fit replacement insert for T-Max Q-Cut series toolholders using the N151.2 insert style with a seat size of 40. Specific toolholder compatibility should be verified against the N151.2-400-5F 1125 designation in the SANDVIK COROMANT T-Max Q-Cut product line documentation.

Installation Notes

Insert seating and clamping should be performed by a qualified machinist following the toolholder manufacturer torque and clamping specifications. Power down and lock out the machine spindle before changing inserts. Inspect the insert pocket and clamping screw for wear or debris before seating the new insert. Do not exceed the recommended depth of cut or feed rate for the 1125 grade as specified in the applicable cutting data tables.
