Sandvik Coromant 7549930 Indexable Drill Insert DS20L5

Product Description

The SANDVIK COROMANT 7549930 is a solid carbide indexable drill insert designed for precision drilling operations in metalworking applications. Manufactured to the DS20 insert style with an L5 chipbreaker geometry, this insert carries a 1344 manufacturer grade and features a Physical Vapor Deposition (PVD)-applied TiAlN coating for enhanced wear resistance and thermal stability at the cutting edge. The inscribed circle measures 8.88 mm, and the corner radius is 0.35 mm, making it suited for demanding hole-making work where tight tolerances and consistent performance are required. Installation and tool changes are handled by machinists and CNC operators working with compatible SANDVIK COROMANT indexable drill bodies.

This insert is intended for use in indexable drill systems operating in ferrous and non-ferrous machining environments, including production turning centers, CNC machining centers, and drill press setups. The right-hand cutting orientation suits standard rotation spindles. The irregular insert shape and DS20 style are specific to SANDVIK COROMANT indexable drill platforms that accept this insert geometry and size designation (0306). It is sold individually, with a minimum order quantity of 10 pieces per order.

Key Features

• DS20 insert style with L5 chipbreaker for controlled chip evacuation during drilling
• TiAlN coating applied via PVD process for high-temperature wear resistance
• 1344 manufacturer grade solid carbide substrate for rigidity and edge retention
• 8.88 mm inscribed circle with 0.35 mm corner radius for precise fit and finish
• Right-hand cutting orientation for standard spindle rotation
• Irregular insert shape sized at 0306 for compatibility with specific drill body pockets

Compatibility

Designed for use in SANDVIK COROMANT indexable drill bodies that accept DS20-style inserts with a 0306 insert size designation and right-hand cutting geometry. Consult the SANDVIK COROMANT tooling catalog to confirm pocket and clamping compatibility before ordering.

Installation Notes

Insert changes should be performed by qualified machinists with the machine powered down and the spindle fully locked. Use the correct torx or hex key specified by the drill body manufacturer when seating the clamping screw — do not overtighten, as carbide inserts are brittle and can fracture under excessive clamp load. Inspect the insert pocket and clamping components for wear or debris before installing a new insert. Follow the tooling manufacturer's recommended cutting parameters for feed rate and speed to achieve full insert life.
