Sandvik Coromant 5756168 Indexable Drill Insert WCMX53

Product Description

The SANDVIK COROMANT 5756168 is a solid carbide indexable drill insert designed for use in indexable insert drills in metal-cutting machining operations. Formed in the WCMX trigon insert style with a 53 chipbreaker geometry, this insert features a Physical Vapor Deposition (PVD) Titanium Nitride (TiN) coating applied over a solid carbide substrate in manufacturer grade 1020. The inscribed circle measures 0.375 inches (9.53 mm), thickness is 0.1563 inches (5/32 inch), and the corner radius is 0.80 mm (0.0315 inches). A 7-degree relief angle supports clean chip evacuation during drilling. Installed by machinists and tooling technicians in production and job-shop environments.

This insert is suited for indexable insert drill bodies that accept WCMX-style trigon inserts in size 6. Typical applications include through-hole and blind-hole drilling in steel, cast iron, and similar ferrous workpieces in both CNC machining centers and manual turning or milling setups. The TiN coating extends tool life in general-purpose cutting conditions. The 53 chipbreaker geometry assists with chip control at moderate feed rates. This insert ships individually but carries a minimum order quantity of 10 units.

Key Features

• Solid carbide substrate in manufacturer grade 1020 for consistent hardness and wear resistance
• PVD Titanium Nitride (TiN) coating for extended tool life in general-purpose drilling
• WCMX trigon insert style with 53 chipbreaker geometry for controlled chip formation
• 0.375-inch (9.53 mm) inscribed circle with 0.80 mm corner radius
• 7-degree relief angle supports clean cutting action and reduced flank wear
• Insert size 6 with 3.70 mm mounting hole diameter for secure seating in compatible drill bodies

Compatibility

Designed for use in indexable insert drill bodies that accept WCMX trigon-style inserts at insert size 6. Confirm drill body manufacturer specifications for insert pocket geometry and screw torque requirements before installation.

Installation Notes

Installation is performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and locked out before changing inserts. Seat the insert firmly in the pocket and tighten the clamping screw to the drill body manufacturer's specified torque using the correct Torx or hex key. Inspect the insert pocket for wear or damage each time inserts are indexed or replaced.
