Sandvik Coromant 5737170 Cutoff Insert 2mm T-max Q-cut

Product Description

The SANDVIK COROMANT 5737170 is a solid carbide cutoff insert for parting and grooving operations on CNC lathes and turning centers. It carries the manufacturer designation N151.2-200-5E 1125 and belongs to the T-Max Q-Cut series. The insert delivers a 2.00 mm (0.0787 inch) cutting width with a neutral lead angle and a 7-degree relief angle, making it suited for straight, on-center parting cuts. A PVD-applied TiAlN coating promotes heat resistance and extended edge life in steel and stainless steel applications. Machinists and CNC setup technicians are the primary installers of this insert.

This insert is designed for use in T-Max Q-Cut parting and grooving toolholders that accept the N151.2 insert style with a size code 20 seat. It fits a broad range of turning center applications where precision parting, recessing, or external grooving is required. The 5E chipbreaker geometry assists with chip control in medium-duty cutting conditions. The 0.20 mm (0.0079 inch) corner radius provides a defined edge without a full-radius profile, keeping dimensional accuracy consistent at the cut-off face.

Key Features

• Solid carbide construction with PVD-applied TiAlN coating for wear and heat resistance
• 2.00 mm cutting width (0.0787 inch) for precise parting and grooving
• Neutral lead angle and neutral hand for straight on-center parting cuts
• 7-degree relief angle reduces rubbing and supports edge clearance
• 5E chipbreaker geometry aids chip evacuation in medium-duty operations
• 0.20 mm corner radius; not a full-radius profile

Compatibility

Designed for T-Max Q-Cut toolholders and insert seats accepting the N151.2 insert style with seat size 20. Verify toolholder seat geometry and clamping method before installation.

Installation Notes

Insert installation and replacement should be performed by a qualified machinist or CNC technician with the machine in a full stop and locked-out state per applicable lockout/tagout procedures. Use the correct insert key or torx wrench specified by the toolholder manufacturer when seating the clamp. Inspect the insert pocket and clamp for wear or debris before installing a new insert. Never exceed the cutting parameters recommended in the T-Max Q-Cut application guide for this insert style and grade.
