Built to DIN standards, it features a 140-degree conical point angle with web thinning for improved centering and reduced thrust on entry. The two-flute spiral design promotes efficient chip evacuation during through and blind-hole operations. At 11.50 mm in diameter with an overall length of 102 mm (approximately 4.02 inches), this bit fits standard straight-cylindrical shank toolholders. Coolant-through capability supports extended tool life in production environments. Licensed machinists and CNC operators are the primary installers and users of this tool.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for screw machine, CNC turning, and general machining applications where short, rigid cutting tools are required. The screw machine length format reduces deflection and improves hole accuracy in close-tolerance work. A maximum drilling depth of 40 mm and a flute-to-diameter ratio of 3xD make it well matched to production drilling of steel components in both job shop and high-volume manufacturing settings. The SD203A series designation indicates SECO high-performance geometry optimized for steel cutting.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in steel drilling\u003c\/li\u003e\n\u003cli\u003e140-degree conical point with web thinning for fast, accurate entry\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports heat management in high-cycle applications\u003c\/li\u003e\n\u003cli\u003eScrew machine length format minimizes deflection and maximizes hole accuracy\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eDIN standard compliance for dimensional consistency\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a replacement-style screw machine drill bit for straight-cylindrical shank toolholders accommodating a 12.00 mm shank diameter, suitable for CNC machining centers, drill presses, and screw machine setups configured for the SD203A series geometry.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis drill bit is installed and operated by machinists and CNC technicians following standard tooling change procedures. Ensure the machine spindle is fully stopped and locked out before inserting or removing the bit from the toolholder. Verify collet or chuck bore size is compatible with the 12.00 mm straight-cylindrical shank before clamping. Follow machine manufacturer guidelines and applicable shop safety standards for toolholder torque and coolant pressure settings.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 11.50 mm (0.4528 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 102 mm (4.02 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 55.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 12.00 mm (0.4724 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 45.00 mm (1.77 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 40.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 2.10 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Conical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral (Regular)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: m7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: SD203A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: DIN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.251 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SECO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 03046015\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51558874939698,"sku":"03046015","price":338.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3f272acf10e704a07fb4cf8c86653616.jpg?v=1786421533","url":"https:\/\/voomisupply.com\/products\/seco-03046015-carbide-screw-machine-drill-bit-11-50mm","provider":"Voomi Supply","version":"1.0","type":"link"}
