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.\u003c\/p\u003e\u003cp\u003eThis 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.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide substrate for high hardness and wear resistance in drilling applications\u003c\/li\u003e\n\u003cli\u003eTiCN and Al2O3 dual-layer PVD coating for thermal protection and extended tool life\u003c\/li\u003e\n\u003cli\u003eDS20 insert style with L5 chipbreaker geometry for controlled chip evacuation\u003c\/li\u003e\n\u003cli\u003e13.36 mm inscribed circle with 0.35 mm corner radius for precise cutting geometry\u003c\/li\u003e\n\u003cli\u003eIrregular insert shape provides positive indexing and secure seating in the drill body\u003c\/li\u003e\n\u003cli\u003eManufacturer grade 1144 for consistent performance and interchangeability\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in SANDVIK COROMANT indexable insert drill bodies that accept DS20-style inserts with insert size designation 0508.
