Sandvik Coromant 5735052 LCMX53 Indexable Drill Insert Grade 3040

Product Description

The SANDVIK COROMANT 5735052 is a solid carbide indexable drill insert in the LCMX style with chipbreaker designation 53 and manufacturer grade 3040. It features a multi-layer MTCVD-applied coating of TiCN and Al2O3 for improved wear resistance and heat management during drilling operations. The insert measures 7/32 inch (0.2188 inches) inscribed circle and 1/8 inch (0.1250 inches) thick, with a 0.80 mm corner radius. Right-hand cutting direction. Designed for use in indexable drill bodies that accept LCMX-style inserts, this part is installed by machinists and tooling technicians in production and job-shop environments.

This insert is suited for indexable drilling applications in metal-cutting operations across manufacturing environments. The LCMX style fits standard drill bodies designed for that insert geometry. The grade 3040 carbide substrate combined with the TiCVD TiCN and Al2O3 coating makes it appropriate for moderate to demanding drilling conditions in ferrous and similar materials. Typical applications include through-hole and blind-hole drilling on CNC machining centers and lathes with live tooling. The insert size designation is 3, with a rectangle shape and a 7-degree relief angle.

Installation Notes

Installation is performed by a qualified machinist or tooling technician. Power down and lock out the machine spindle before replacing inserts. Use the appropriate torx or hex key to the drill body manufacturer's specified seating procedure — do not overtighten the clamping screw. Inspect the insert pocket and clamping seat for damage or debris before seating the new insert.
