Sandvik Coromant 7549965 Indexable Drill Insert DS20L5

Product Description

The SANDVIK COROMANT 7549965 is a solid carbide indexable drill insert designed for use in indexable insert drills in demanding machining operations. Classified under insert style DS20 with chipbreaker geometry L5, this insert carries manufacturer grade 1144 and features a dual-layer TiCN and Al2O3 coating applied via PVD process. The inscribed circle measures 13.36 mm with a 0.35 mm corner radius and an irregular insert shape. Intended for installation by machinists and tooling technicians in CNC or manual drilling setups, this insert delivers wear resistance and thermal stability across a range of workpiece materials.

This insert is suited for metal-cutting and drilling applications in industrial machining environments, including aerospace, automotive, and general manufacturing production. The DS20 insert style is used in compatible SANDVIK COROMANT indexable drill toolholders. The L5 chipbreaker geometry is suited for cutting conditions that require controlled chip formation. Insert size designation is 0508. This insert is sold individually and is a direct replacement component for worn or damaged inserts in existing drill bodies.

Key Features

• Solid carbide substrate for high hardness and wear resistance in drilling applications
• TiCN and Al2O3 dual-layer PVD coating for thermal protection and extended tool life
• DS20 insert style with L5 chipbreaker geometry for controlled chip evacuation
• 13.36 mm inscribed circle with 0.35 mm corner radius for precise cutting geometry
• Irregular insert shape provides positive indexing and secure seating in the drill body
• Manufacturer grade 1144 for consistent performance and interchangeability

Compatibility

Designed for use in SANDVIK COROMANT indexable insert drill bodies that accept DS20-style inserts with insert size designation 0508. Verify toolholder specifications before installation to confirm correct insert style and geometry match.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician with the machine fully powered down and the spindle locked before servicing the drill body. Use the correct torque wrench and insert screw recommended by the toolholder manufacturer — do not overtighten or cross-thread the clamping screw. Inspect the insert pocket for debris or damage before seating the new insert, and confirm proper indexing before resuming operations.
