Sandvik Coromant 5741826 Cutoff Insert 3 Mm T-max Q-cut

Product Description

The SANDVIK COROMANT 5741826 is a solid carbide cutoff insert designed for parting and grooving operations on CNC lathes and turning centers. It carries a 3.00 mm (0.1181 inches) cutting width and a 5-degree right-hand lead angle, making it suited for precision cutoff work where controlled chip evacuation and dimensional accuracy are critical. The insert uses a TiAlN coating applied via PVD process, which improves wear resistance and extends tool life in steel and stainless applications. The 7E chipbreaker geometry and manufacturer grade 1125 are matched to moderate cutting conditions. Licensed machinists and CNC turning operators are the primary installers of this insert type.

This insert fits within the T-Max Q-Cut system from SANDVIK COROMANT, series R151.2. It is intended for use in compatible T-Max Q-Cut insert holders that accept the R151.2-300 style seat with an insert seat size of 30. The right-hand insert hand and right-hand lead angle direction indicate mounting on standard right-hand toolholder configurations. Typical applications include cutoff, parting, and shallow grooving on bar stock in production turning environments, both high-mix and high-volume.

Key Features

• Solid carbide construction with PVD-applied TiAlN coating for extended wear resistance
• 3.00 mm cutting width (0.1181 inches) for precise parting and grooving
• 5-degree right-hand lead angle improves chip direction and reduces deflection
• 7E chipbreaker geometry for effective chip control in moderate-feed operations
• 0.15 mm (0.0059 inches) corner radius for a clean parting surface finish
• Clamp-style insert holding method for secure, repeatable seating in the holder

Compatibility

Designed for use with SANDVIK COROMANT T-Max Q-Cut toolholders that accept the R151.2 insert style with an insert seat size of 30 and a 3.00 mm seat width. Verify holder compatibility with the R151.2-300 05-7E designation before ordering.

Installation Notes

Insert replacement should be performed by a qualified machinist with the machine spindle fully stopped and the turret in a safe index position. Use the appropriate SANDVIK COROMANT clamping key or wrench specified for the toolholder to seat the insert without over-torquing the clamp screw. Inspect the insert pocket and clamp for wear or debris before seating a new insert. Follow the toolholder manufacturer guidelines and shop safety protocols for carbide insert handling, as edges are sharp and fragile.
