Sandvik Coromant 5741620 Cutoff Insert 4mm Right Hand

Product Description

The SANDVIK COROMANT 5741620 is a solid carbide cutoff insert designed for parting and grooving operations on CNC lathes and turning centers. It carries insert style R151.2 with a 4.00 mm (0.1575 inches) cutting width and a TiAlN coating applied via PVD process, which supports extended tool life in steel and stainless applications. The 5E chipbreaker geometry and 5-degree right-hand lead angle promote controlled chip flow during deep parting cuts. Licensed HVAC and machining professionals, toolroom technicians, and production machinists specify this insert for precision cutoff work where consistent width and surface finish are critical.

This insert is suited for right-hand parting and grooving setups in medium to high production turning environments. It fits T-Max Q-Cut toolholders and blade systems that accept size-40 insert seats. The R151.2-400 05-5E 1125 designation identifies the insert style, seat size, chipbreaker, and manufacturer grade, making cross-referencing to compatible holders straightforward. Typical applications include bar stock cutoff, groove profiling, and face grooving on ferrous and non-ferrous workpieces where dimensional repeatability is required.

Key Features

• Solid carbide construction with grade 1125 for balanced toughness and wear resistance
• TiAlN coating via PVD process for elevated heat resistance and extended edge life
• 4.00 mm cutting width (0.1575 inches) with 0.20 mm corner radius for consistent groove geometry
• 5E chipbreaker controls chip formation during parting and grooving passes
• Right-hand, 5-degree lead angle reduces cutting forces and promotes smooth entry
• 7-degree relief angle minimizes workpiece contact and reduces flank wear

Compatibility

Designed for use with T-Max Q-Cut toolholders and blades that accept R151.2-style, size-40 insert seats in right-hand configurations.

Installation Notes

Insert installation should be performed by a qualified machinist or toolroom technician with the machine in a full stop and lockout-tagout procedures followed per applicable safety standards. Seat the insert fully in the clamp-style holder and verify clamp torque per the toolholder manufacturer specification before resuming operation. Inspect the insert seat and clamping screw for wear or debris before each insert change. Do not exceed the cutting parameters recommended for grade 1125 in the relevant material group.
