Sandvik Coromant 5737991 Grooving Insert T-max Q-cut

Product Description

The SANDVIK COROMANT 5737991 is a solid carbide grooving insert in the T-Max Q-Cut series, designed for precision grooving and parting operations on CNC lathes and turning centers. The insert carries a PVD-applied TiAlN and AlCr2O3 coating for wear resistance and extended tool life at elevated cutting temperatures. At 0.094 inches (3/32 inch) cutting width with a neutral hand orientation and a 0.007 inch corner radius, this insert delivers consistent groove geometry in demanding production environments. Grade 1145 makes it well suited for ferrous and difficult-to-machine materials. Machinists and CNC tooling technicians are the primary users in both job shop and high-volume production settings.

This insert is used in external and face grooving applications on CNC turning machines where tight groove-width tolerances and surface finish consistency are required. The neutral rake and 4G chip breaker geometry support stable chip control across a range of depths of cut and feed rates. It is applicable in both roughing and finishing grooving passes in automotive, aerospace, and general metalworking operations. The insert seat size 25 and ISO code N151.3-A094-25-4G 1145 identify the compatible toolholder family for direct selection.

Key Features

• Solid carbide substrate with PVD TiAlN and AlCr2O3 multilayer coating for elevated heat and wear resistance
• 0.094 inch (2.39 mm) cutting width with tight corner radius of 0.007 inch (0.18 mm) for accurate groove profiles
• Neutral hand orientation compatible with standard T-Max Q-Cut right- and left-hand toolholders
• 4G chip breaker geometry promotes reliable chip evacuation during grooving and parting operations
• Grade 1145 carbide designed for consistent performance in ferrous and difficult-to-machine alloy applications
• Multi-use insert suitable for grooving, parting, and profiling in a single toolholder system

Compatibility

This insert is identified by ISO code N151.3-A094-25-4G 1145 and is designed for use with SANDVIK COROMANT T-Max Q-Cut toolholders accepting insert seat size 25 in the N151.3 series.

Installation Notes

Insert installation should be performed by a qualified CNC machinist or tooling technician with the machine in a full stop and lockout-tagout procedures followed before accessing the toolholder. Seat the insert firmly into the toolholder pocket and verify clamping is secure before resuming spindle operation. Inspect the insert seat for chips or debris that could affect seating and groove geometry. Always verify ISO code and seat size compatibility between the insert and toolholder before installation.
