Sandvik Coromant 5733662 LCMX53 Indexable Drill Insert

Product Description

The SANDVIK COROMANT 5733662 is a solid carbide indexable drill insert in the LCMX53 style, manufactured to grade 1020 with a PVD-applied Titanium Nitride (TiN) coating. This insert features a rectangular shape with a 7-degree relief angle, a 1/4-inch (0.2500 inch) inscribed circle, and a 0.80 mm corner radius. It is designed for use in indexable insert drills where consistent hole quality and tool longevity are priorities. Licensed machinists, toolroom technicians, and CNC operators install these inserts as replaceable cutting elements in compatible drill bodies.

This insert is suited for indexable drilling operations in metalworking environments, including general machining shops and production facilities. The LCMX53 chipbreaker geometry is engineered for controlled chip formation during drilling cycles. The TiN coating provides a hard, wear-resistant surface layer that extends cutting life in a range of ferrous and non-ferrous workpiece materials. Insert size 4 with a 2.80 mm hole diameter seats into compatible SANDVIK COROMANT and equivalent drill bodies designed for the LCMX insert family.

Key Features

• Solid carbide substrate with PVD Titanium Nitride coating for extended wear life
• LCMX53 chipbreaker for controlled chip evacuation during drilling
• 1/4-inch inscribed circle (0.2500 inch / 6.35 mm) for precise seat fit
• 0.80 mm corner radius minimizes stress concentration at cutting edges
• 7-degree relief angle supports clean entry and reduced cutting forces
• Insert size 4 with 2.80 mm mounting hole diameter

Compatibility

Designed as an OEM-style replacement indexable drill insert for drill bodies accepting the LCMX insert style with a size 4 seat and 2.80 mm hole diameter.

Installation Notes

Indexable drill inserts should be installed and replaced by qualified machinists or toolroom personnel familiar with the drill body manufacturer's seating and torque procedures. Ensure the machine spindle is fully stopped and locked out before changing inserts. Clean the insert pocket thoroughly before seating the new insert to prevent premature edge failure from debris or contamination. Follow the drill body manufacturer's clamping guidelines for proper insert retention.
