Sandvik Coromant 5735056 Indexable Drill Insert LCMX58

Product Description

The SANDVIK COROMANT 5735056 is a solid carbide indexable drill insert designed for use in indexable insert drills in demanding metal-cutting operations. The insert carries the LCMX58 style designation with a square shape and a 7-degree relief angle, making it suited for stable, positive-engagement drilling in a wide range of workpiece materials. A CVD-applied TiCN/TiN coating provides wear resistance and heat dissipation during high-speed cutting cycles. At 0.1252 inches thick with a 0.40 mm corner radius, this insert delivers consistent edge geometry across its usable cutting edges. Installation and replacement are handled by qualified machinists or tooling technicians as part of routine insert indexing.

This insert is intended for use in compatible LCMX-style indexable drill bodies used in CNC machining centers, lathes with live tooling, and dedicated drill presses in both production and job-shop environments. The right-hand cutting direction suits standard spindle rotation configurations. The chipbreaker designation 58 is matched to the LCMX insert family for chip control during through-hole and blind-hole drilling applications. Consult the drill body manufacturer specifications to confirm insert size 040304 compatibility before installation.

Key Features

• Solid carbide substrate for rigidity and wear resistance in metal-cutting applications
• CVD-applied TiCN/TiN dual-layer coating for thermal and abrasion resistance
• Square LCMX insert style with chipbreaker designation 58
• 7-degree relief angle for positive cutting engagement
• 0.40 mm corner radius (0.0157 inches) for controlled edge transition
• Right-hand cutting direction for standard spindle rotation compatibility

Compatibility

Designed for use with LCMX-style indexable drill bodies that accept insert size 040304 with a 2.80 mm (0.1102 inch) mounting hole diameter. Verify drill body manufacturer specifications for insert grade and chipbreaker compatibility prior to use.

Installation Notes

Insert indexing and replacement should be performed by a qualified machinist or tooling technician with the machine fully powered down and locked out per applicable OSHA lockout/tagout procedures. Use the correct torx or hex key to the drill body manufacturer torque specification for the clamping screw — do not overtighten or undertighten, as improper clamping affects runout and edge life. Inspect the insert pocket and clamping components for debris or wear before seating the new insert. Handle carbide inserts with care to avoid chipping the cutting edges prior to use.
