Sandvik Coromant 7549964 Indexable Drill Insert DS20L5

Product Description

The SANDVIK COROMANT 7549964 is a solid carbide indexable drill insert designed for use in indexable drill bodies that accept DS20-style inserts. Manufactured to the 1344 grade with a PVD-applied TiAlN coating, this insert delivers wear resistance and thermal stability in demanding drilling operations. The irregular insert shape features a 13.36 mm inscribed circle and a 0.35 mm corner radius, contributing to stable cutting action and controlled chip formation. The L5 chipbreaker geometry is suited to a right-hand cutting orientation. Machinists and tool-and-die professionals install this insert into compatible drill holders for ferrous and non-ferrous metal drilling applications.

This insert is used in production drilling environments where indexable tooling systems are preferred over solid round tools. Typical applications include CNC machining centers and turning centers performing hole-making operations in steel, stainless, and similar workpiece materials. The DS20 insert style and size code 0508 identify the specific seat geometry required in the drill body. Right-hand cutting direction applies to standard spindle rotation. This insert ships individually but carries a minimum order quantity of 10 units.

Key Features

• Solid carbide substrate for rigidity and edge retention in interrupted and continuous cuts
• PVD TiAlN coating for oxidation resistance and extended tool life at elevated cutting temperatures
• 13.36 mm inscribed circle with DS20 insert style and size code 0508
• 0.35 mm corner radius for controlled edge geometry
• L5 chipbreaker designed for right-hand cutting direction
• Irregular insert shape optimized for indexable drill seat geometry

Compatibility

Designed for use in drill bodies and holders that accept DS20-style indexable insert seats with insert size code 0508 and a right-hand cutting configuration. Verify seat geometry and clamping system compatibility with the drill body manufacturer before installation.

Installation Notes

Installation of indexable inserts should be performed by a qualified machinist or toolroom technician. Ensure the drill body, insert seat, and clamping screw are clean and free of chips or debris before seating the insert. Use the correct torque driver and insert screw specified by the drill body manufacturer — do not over-torque the clamping screw. Inspect the insert seat for wear or damage at each index interval.
