Sandvik Coromant 5753356 TLGP3125 Grooving Insert Left Hand

Product Description

The SANDVIK COROMANT 5753356 is a solid carbide grooving insert in the Top Lok series, designed for precision grooving and parting operations on CNC lathes and turning centers. The insert carries ISO code TLGP3125L2135 and is manufactured to grade 2135 with a multi-layer MT-CVD coating of TiCN, Al2O3, and TiN applied in sequence for wear resistance and thermal stability. The cutting width is 0.125 inches with a maximum depth of cut of 0.15 inches and a corner radius of 0.0075 inches. Left-hand orientation and a 10-degree rake angle suit specific toolholder configurations. Licensed machinists and CNC operators install this insert on production turning equipment.

This insert is suited for grooving, undercutting, and light parting operations on ferrous and non-ferrous workpieces in both production and job-shop environments. The Top Lok series designation means it is matched to compatible Top Lok toolholders and blade systems. The insert size designation 3125 identifies the shank and pocket interface, and the grade 2135 is formulated for general-purpose steel and stainless steel cutting at moderate to high speeds. The multi-use rating confirms it can be applied across varied material classes within its depth-of-cut range of 0.15 to 0.20 inches.

Installation Notes

Insert seating and clamping should be performed by a qualified CNC machinist following the toolholder manufacturer torque guidelines for the Top Lok clamping screw. Power down and lock out the machine spindle before changing inserts. Inspect the insert pocket for chips or debris that could affect seating and lead to premature edge failure. Follow shop safety protocols and applicable OSHA machine-guarding requirements during tooling changes.
