Sandvik Coromant 7549931 Indexable Drill Insert DS20L5

Product Description

The SANDVIK COROMANT 7549931 is a solid carbide indexable drill insert designed for use in modular drilling systems where precise hole-making is required. The insert features an irregular shape with the DS20L5 insert style, a manufacturer grade of 1144, and a PVD-applied TiCN and Al2O3 coating that provides wear resistance and thermal stability during cutting operations. The inscribed circle measures 8.88 millimeters with a corner radius of 0.35 millimeters. This insert is installed by machinists and tooling technicians working in metal-cutting, production drilling, and precision machining environments where indexable tooling systems are standard.

This insert is suited for use in right-hand cutting drilling applications on CNC machining centers, turning centers, and drill press setups where DS20-style insert seats are specified. The L5 chipbreaker geometry is designed to manage chip flow effectively during drilling operations. It is appropriate for production environments handling steel, cast iron, and similar ferrous workpiece materials where a coated carbide grade is the standard tool selection.

Key Features

• DS20L5 insert style with irregular shape and L5 chipbreaker geometry for controlled chip evacuation
• Solid carbide substrate with PVD-applied TiCN and Al2O3 dual-layer coating for extended tool life
• 8.88 millimeter inscribed circle with 0.35 millimeter corner radius for consistent cutting geometry
• Right-hand cutting direction for standard CNC and conventional drilling setups
• Manufacturer grade 1144 for balanced hardness and toughness in ferrous material drilling

Compatibility

Designed as an OEM-style replacement indexable drill insert for DS20-seat modular drilling systems that accept an insert size 0306 with an irregular shape profile.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. The machine spindle must be fully de-energized and locked out before inserting or indexing the cutting insert. Use the appropriate torx or insert-clamp wrench specified for the toolholder to secure the insert without over-torquing the clamping screw. Inspect the insert pocket and seating surface for chips or debris before seating the new insert to ensure proper contact and cutting geometry.
