It is designed for use in indexable twist drill bodies within the DR-TWIST series. With a 16 mm (0.6299 inches) inscribed circle, a 0.2189-inch thickness, and a 1.2 mm corner radius, this insert delivers consistent cutting geometry across a wide range of workpiece materials. Installation is performed by machinists and toolroom technicians setting up multi-insert drilling operations on CNC or manual machining equipment.\u003c\/p\u003e\n\u003cp\u003eThis insert is rated for universal workpiece material compatibility, covering ISO material groups H, K, M, P, and S, placing it within the P15-P30 material grade range. It is suited for production drilling applications in general machining, aerospace component work, and steel fabrication where consistent hole quality and insert indexability are required. The 90-degree included angle and square shape make it appropriate for flat-bottomed or standard through-hole drilling operations using compatible DR-TWIST series drill bodies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eIC808 PVD-coated solid carbide grade rated for P15-P30 material range\u003c\/li\u003e\n  \u003cli\u003e16 mm inscribed circle (0.6299 inches) with square SOMT geometry\u003c\/li\u003e\n  \u003cli\u003e1.2 mm corner radius for controlled edge engagement\u003c\/li\u003e\n  \u003cli\u003eDT chipbreaker designation for chip management during drilling\u003c\/li\u003e\n  \u003cli\u003eUniversal material compatibility across ISO groups H, K, M, P, and S\u003c\/li\u003e\n  \u003cli\u003eConforms to ISO 13399 insert identification standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in ISCAR DR-TWIST series indexable drill bodies that accept SOMT16 style inserts with insert size code 16.

Use the correct torque wrench and insert screw specified by the drill body manufacturer to seat the insert properly — do not overtighten or use improvised tooling. Inspect the pocket seating surface for debris or wear before placing a new insert. Follow the drill body manufacturer's recommended cutting parameters for feed rate and speed based on workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: SOMT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: IC808\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated (PVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Square\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 16 mm (0.6299 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 16 mm (0.6290 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.6290 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.2189 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1.2 mm (0.0472 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: DT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: DR-TWIST\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade Range\u003c\/strong\u003e: P15-P30\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Universal (H, K, M, P, S)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 16 (160512)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ISO 13399\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ISCAR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5507878\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51730491212082,"sku":"5507878","price":316.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/eff3c04473156526696800ff2c1fac90.jpg?v=1788718412","url":"https:\/\/voomisupply.com\/products\/iscar-5507878-somt16dt-ic808-indexable-drill-insert-square","provider":"Voomi Supply","version":"1.0","type":"link"}
