Sandvik Coromant 5741581 Cutoff Insert 3mm T-max Q-cut

Product Description

The SANDVIK COROMANT 5741581 is a solid carbide cutoff and grooving insert designed for parting and shallow grooving operations on CNC lathes and turning centers. Built to Insert Style R151.2 with a 3.00 mm (0.1181 inch) cutting width, this insert uses an MTCVD-applied TiCN/Al2O3/TiN multilayer coating for extended tool life in steel and cast iron applications. The 5E chipbreaker geometry controls chip flow in moderate-feed cutoff work. The Manufacturer Grade 4225 substrate balances wear resistance and toughness. Machinists and CNC operators install this insert as a direct replacement or scheduled consumable in T-Max Q-Cut toolholders.

This insert is suited for production turning environments where consistent part-off quality and predictable insert life are required. The right-hand lead angle orientation and 5-degree lead angle direct cutting forces into the workpiece for stable grooving. A 0.20 mm corner radius (0.0079 inch) reduces stress concentration at the groove corner. The 7-degree relief angle provides clearance in standard cutoff applications. This insert fits T-Max Q-Cut series clamping systems using Insert Seat Size 30 holders, typical in both light industrial and high-production turning cells.

Key Features

• Solid carbide construction with MTCVD TiCN/Al2O3/TiN multilayer coating for wear resistance
• 3.00 mm cutting width with right-hand lead angle for directional cutting force control
• 5E chipbreaker geometry for effective chip control at moderate feed rates
• Manufacturer Grade 4225 substrate balances toughness and crater resistance
• 0.20 mm corner radius reduces notch stress at groove bottom
• Clamp-style insert holding method compatible with T-Max Q-Cut Seat Size 30 toolholders

Compatibility

Designed for use with T-Max Q-Cut series clamping toolholders accepting Insert Seat Size 30 and Insert Style R151.2. No additional specific model compatibility data was provided in the product input.

Installation Notes

Installation of cutoff inserts should be performed by a qualified machinist or CNC technician with the machine in a locked-out, zero-energy state before any insert change. Seat the insert fully into the clamp pocket and verify the clamping screw torque using the toolholder manufacturer's guidelines. Inspect the insert seat for chips or contamination before seating the new insert, as debris will affect runout and cutting performance. Confirm correct coolant flow direction before resuming production.
