Sandvik Coromant 5753421 Grooving Insert Solid Carbide Top Lok

Product Description

The SANDVIK COROMANT 5753421 is a solid carbide grooving insert designed for precision grooving operations on CNC lathes and turning centers. Carrying the TLR chip breaker style with a positive rake geometry, this left-hand insert delivers clean, controlled chip formation during external and internal grooving applications. The cutting width measures 0.124 inches (3.15 mm) with a maximum depth of cut of 0.150 inches (3.81 mm). The uncoated bright finish makes it well suited for non-ferrous materials and applications where coating buildup or adhesion is a concern. Machinists and tooling specialists working in production turning environments will find this insert fits directly into compatible Top Lok grooving toolholders.

This insert is intended for grooving applications in both production and job-shop turning environments. The left-hand orientation suits specific toolholder configurations where the cut is made from the left side of the workpiece. With a positive rake and the TLR chip breaker, it performs consistently in shallow to moderate-depth grooving passes. The insert size is 3L, fitting Top Lok Series 3 seat toolholders. The ISO code for this insert is TLR-3062L H13A, also referenced as the manufacturer catalog number TLR-3062L H13A. It is sold individually but subject to a minimum order quantity of 10 pieces.

Installation Notes

Insert replacement should be performed by a qualified machinist or tooling technician with the machine fully powered down and the spindle locked. Use the appropriate torx or clamping key specified by the toolholder manufacturer to secure the insert without overtightening. Inspect the insert seat for debris or damage before seating the new insert. Follow the toolholder manufacturer guidelines for clamping torque and insert orientation before returning the machine to service.
