Sandvik Coromant 7549910 Indexable Drill Insert DS20H5W

Product Description

The SANDVIK COROMANT 7549910 is a solid carbide indexable drill insert designed for precision drilling operations in metalworking and machining applications. Built to the DS20 insert style with an H5W chipbreaker geometry, this insert carries a 4334 manufacturer grade and features a multi-layer CVD coating of TiCN, Al2O3, and TiN for enhanced wear resistance and thermal stability. The 0.5 mm corner radius suits applications where controlled edge geometry is critical. Measuring 3.74 inches in length, 1.58 inches in height, and 0.53 inches in width, it is sized for standard indexable drill tooling systems. Machinists and toolroom technicians working in production or job-shop environments are the primary installers of this insert.

This insert is suited for indexable drill bodies that accept DS20-style inserts in industrial machining settings, including CNC turning centers, machining centers, and drill press applications targeting metal stock removal. The irregular shape designation indicates this insert is engineered for a specific seating pocket geometry within compatible toolholders. The H5W chipbreaker promotes chip control across a range of feed rates typical in steel and cast-iron drilling. This insert ships in individual unit packaging with a minimum order quantity of 10 units.

Key Features

• Weighs 0.085 pounds per unit; compact form factor for high-density tooling magazines

Compatibility

Designed as an OEM-style replacement or direct-fit insert for indexable drill toolholders accepting DS20 insert style geometry with an irregular seating pocket.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician with the spindle or machine fully powered down and locked out before servicing the toolholder. Use the correct Torx or hex key as specified by the toolholder manufacturer to seat the insert clamp screw — do not overtighten or force the insert into the pocket. Verify insert orientation and chipbreaker position match the toolholder pocket before resuming operation. Follow the machine manufacturer and toolholder OEM documentation for clamping sequence and runout inspection.
