Sandvik Coromant 5846606 Grooving Insert TLR4LTLR Solid Carbide

Product Description

The SANDVIK COROMANT 5846606 is a solid carbide grooving insert in the Top Lok series, designed for precision grooving and parting operations on CNC lathes and turning centers. It features a TiAlN coating applied via PVD process, which provides thermal resistance and extended tool life in steel, stainless, and cast iron applications. The insert is left-hand oriented with a 0.25 inch cutting width, a maximum depth of cut of 0.25 inch, and a positive rake geometry that reduces cutting forces and promotes clean chip evacuation. This insert is installed and changed by machinists and CNC lathe operators in production and job-shop environments.

This insert is suited for grooving, recessing, and parting-off operations in both low-volume job-shop and high-volume production turning applications. The TLR chip breaker geometry targets controlled chip formation across a depth-of-cut range of 0.20 inch to 0.30 inch. With an insert seat size of 4 and ISO code TLR-4125L 1125, it indexes into compatible Top Lok toolholders. The multi-use designation means the insert can handle grooving on outer diameters. It is sold individually with a minimum order quantity of 10 units.

Compatibility

Designed for use with SANDVIK COROMANT Top Lok series grooving toolholders accepting insert seat size 4, as identified by ISO code TLR-4125L 1125. Verify toolholder seat size and hand orientation before ordering.

Installation Notes

Installation is performed by a qualified machinist or CNC lathe operator. Power down and lock out the machine before indexing or replacing inserts. Use the appropriate Top Lok clamping key to seat and secure the insert fully before resuming cuts. Do not exceed the rated maximum depth of cut or use the insert in a toolholder it was not designed for, as this can result in insert fracture or workpiece damage.
