Sandvik Coromant 5735054 Indexable Drill Insert LCMX53

Product Description

The SANDVIK COROMANT 5735054 is a solid carbide indexable drill insert in the LCMX53 style, manufactured in grade 1020 with a PVD-applied Titanium Nitride (TiN) coating. This rectangle-shaped insert features a 7/32 inch (0.2188 inch) inscribed circle, a 1/8 inch thickness, and a 0.80 mm corner radius. It is designed for use in indexable drilling tools where consistent cutting geometry and wear resistance are required. Licensed machinists and tool-and-die technicians use this insert in production drilling operations across metalworking environments. The relief angle is 7 degrees, the chipbreaker designation is 53, and the hole diameter is 0.0984 inch.

This insert is suited for indexable drill bodies that accept LCMX-style inserts at insert size 3. It is used in CNC machining centers, drill presses, and turning centers performing through-hole and blind-hole drilling operations in steel and similar ferrous workpiece materials. The TiN coating provides surface hardness and lubricity that extends tool life in moderate-speed drilling applications. Machinists in job shops, production facilities, and maintenance environments use this insert as a direct replacement when the cutting edge is worn or chipped.

Key Features

• Solid carbide substrate with PVD Titanium Nitride coating for extended wear resistance
• LCMX53 insert style with 7-degree relief angle and 53 chipbreaker geometry
• Inscribed circle of 7/32 inch (0.2188 inch) for consistent seating in compatible drill bodies
• Corner radius of 0.80 mm (0.0315 inch) for controlled entry and chip formation
• Mounting hole diameter of 0.0984 inch (2.50 mm) for secure screw-down clamping
• Rectangle shape, insert size 3, 1/8 inch thick construction

Compatibility

Designed for indexable drill bodies accepting LCMX-style inserts at insert size 3 with a 0.0984 inch mounting hole. Verify seating geometry and clamping torque specifications against the drill body manufacturer documentation before installation.

Installation Notes

Installation should be performed by a qualified machinist with the machine fully powered down and the spindle locked before insert exchange. Use the correct Torx or hex key specified by the drill body manufacturer for the clamping screw — do not improvise with undersized drivers. Inspect the pocket seat and clamping screw for debris or damage before seating the new insert. Follow the drill body manufacturer guidelines for clamping sequence to ensure proper insert indexing and prevent premature edge failure.
