Sandvik Coromant 7549967 Indexable Drill Insert DS20M7

Product Description

The SANDVIK COROMANT 7549967 is a solid carbide indexable drill insert engineered for high-performance drilling applications. Carrying the DS20M7 insert style with a manufacturer grade of 1344, this insert features a TiAlN coating applied via PVD process, delivering excellent heat resistance and wear protection at the cutting edge. The inscribed circle measures 13.36 mm with a corner radius of 0.35 mm and an irregular shape geometry. It is designed for right-hand cutting direction and incorporates an M7 chipbreaker to promote controlled chip evacuation during through-hole and blind-hole drilling operations. Machinists and CNC operators in precision machining environments are the primary installers of this insert.

This insert is suited for indexable drill bodies that accept DS20-style inserts in the 0508 insert size designation. It performs in both production-level and job-shop drilling of steel, alloy steel, and similar ferrous materials where TiAlN-coated carbide provides reliable tool life. The irregular shape geometry is specific to drill insert applications rather than general turning or milling, making proper body-to-insert matching essential before installation.

Key Features

• Solid carbide substrate with PVD-applied TiAlN coating for elevated heat and wear resistance
• DS20M7 insert style with M7 chipbreaker geometry for controlled chip formation
• 13.36 mm inscribed circle and 0.35 mm corner radius for precise cutting edge geometry
• Right-hand cutting direction for standard spindle rotation applications
• Irregular shape specific to indexable drill insert body compatibility
• Manufacturer grade 1344 for defined hardness and toughness balance

Compatibility

Designed for indexable drill bodies that accept DS20-style inserts at the 0508 insert size. Verify insert style, inscribed circle, and body seat specifications against the drill body manufacturer documentation before ordering.

Installation Notes

Insert indexing and replacement should be performed by a qualified machinist or tooling technician with the spindle fully stopped and machine locked out per OSHA lockout-tagout procedures. Use the correct torque wrench and insert clamp screw specified by the drill body manufacturer — do not substitute fasteners. Inspect the insert pocket seat for damage, chips, or debris before seating the new insert, as contamination in the seat can cause premature insert failure or dimensional inaccuracy. Handle solid carbide inserts with care to avoid chipping the cutting edges during installation.
