Sandvik Coromant 5741615 Cutoff Insert Carbide 3 Mm

Product Description

The SANDVIK COROMANT 5741615 is a solid carbide cutoff insert designed for parting and grooving operations on CNC lathes and turning centers. It carries the R151.2-300 05-5E 1125 catalog designation and belongs to the T-Max Q-Cut series. The insert features a 3.00 mm (0.1181 inches) cutting width, a 5-degree right-hand lead angle, and a TiAlN coating applied via PVD process. Grade 1125 provides wear resistance suited to medium-to-high cutting speeds on steel and stainless applications. The overall length is 0.2197 inches (5.58 mm). It is installed by machinists and CNC operators using a clamp-style insert holding method.

This insert is used in T-Max Q-Cut toolholders configured for clamp-style seating with an insert seat size of 30. Typical applications include parting off bar stock, grooving external diameters, and producing narrow slots in production turning environments. The 5E chipbreaker geometry is suited for controlled chip formation in medium-feed grooving operations. The right-hand lead angle directs cutting forces away from the workpiece shoulder. A 0.20 mm corner radius (0.0079 inches) provides a minor edge blend without generating a large radius on the finished part.

Key Features

• Solid carbide construction with TiAlN PVD coating for extended tool life on steel and stainless
• 3.00 mm cutting width with 5-degree right-hand lead angle for directed cutting forces
• 5E chipbreaker geometry for controlled chip evacuation in grooving and parting operations
• Clamp-style insert holding method compatible with T-Max Q-Cut toolholder system
• 0.20 mm corner radius for minimal edge blending on finished part surfaces
• 7-degree relief angle reduces rubbing on groove sidewalls

Compatibility

Designed for use in T-Max Q-Cut series clamp-style toolholders with an insert seat size of 30 and insert style R151.2. Verify toolholder designation matches insert hand (right hand) and seat size before installation.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before changing inserts. Use the correct torx or hex key to the clamping screw as specified by the toolholder manufacturer — do not overtighten or use impact tools on insert clamping hardware. Confirm insert seating and clamp engagement before resuming cutting operations.
