Sandvik Coromant 5733671 Indexable Drill Insert LCMX53

Product Description

The SANDVIK COROMANT 5733671 is a solid carbide indexable drill insert designed for use in indexable drill tooling systems. Manufactured in the LCMX insert style with a chipbreaker designation of 53, this insert features a titanium nitride (TiN) coating applied via PVD process for improved wear resistance and surface hardness. It carries a manufacturer grade of 1020 and is suited for drilling operations where edge retention and consistent cutting performance are required. The insert measures 0.25 inches inscribed circle and 0.125 inches thick, with a corner radius of 0.80 mm (0.0315 inches). Licensed machinists and toolroom technicians are the primary installers of this consumable cutting insert.

This insert is intended for use in indexable drilling applications across general machining environments, including metalworking operations in job shops, manufacturing facilities, and production environments. The rectangular shape and 7-degree relief angle make it appropriate for center or peripheral positions in compatible indexable drill bodies. It is sold individually per package, with a minimum order quantity of 10 units, making it suitable for shops maintaining ongoing drill tooling inventory.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the drill body and insert pocket are free of chips and debris before seating the insert. Power down and lock out the machine spindle before removing or indexing inserts. Use the manufacturer-specified torx or hex key at the recommended clamping torque for the insert screw - refer to the drill body documentation for fastener specifications, as no torque value is specified for this insert individually.
