Measuring 6.00 mm in diameter with a 140-degree conical point, it delivers accurate entry and reduced thrust in demanding production environments. The bit features a web-thinned geometry that improves chip evacuation and reduces cutting force at the point. With an overall length of 66.00 mm and a flute length of 28.00 mm, this stub-length drill provides rigidity and resistance to deflection. Coolant-through capability supports continuous high-speed drilling cycles in CNC machining centers and production drill presses. This tool is intended for use by machinists and tool-room technicians.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for screw machine operations, CNC drilling, and production boring applications where short, rigid tooling is required. The SD203A series targets steel as the primary workpiece material, making it a practical choice for general machining shops, job shops, and manufacturing facilities working with mild steel, alloy steel, and similar ferrous metals. The 3xD flute-to-diameter ratio limits the maximum drilling depth to 20.00 mm, keeping this tool optimized for shorter through-holes and blind holes in production runs.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for wear resistance and dimensional stability in steel drilling\u003c\/li\u003e\n\u003cli\u003e140-degree conical point angle reduces thrust and improves self-centering on entry\u003c\/li\u003e\n\u003cli\u003eWeb-thinned geometry promotes efficient chip evacuation and lowers cutting forces\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports high-speed, continuous drilling cycles\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank at 6.00 mm diameter for standard collet and chuck compatibility\u003c\/li\u003e\n\u003cli\u003eDIN-standard SD203A series with m7 diameter tolerance for consistent fit in toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style screw machine length drill bit in the SECO SD203A series, sized for standard 6.00 mm straight-cylindrical shank collets and drill chucks conforming to DIN specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes should be performed by a qualified machinist with the machine powered down and the spindle fully stopped. Secure the straight-cylindrical shank in a properly sized collet or drill chuck to the torque specified by the toolholder manufacturer. Verify coolant-through passages are clear and coolant supply pressure is set per machine specifications before beginning a drilling cycle. Inspect the drill point for chipping or wear before each production run.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 6.00 mm (0.2362 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Conical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 66.00 mm (2.5984 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 28.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6.00 mm (0.2362 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 36.00 mm (1.4173 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 20.00 mm\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\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: m7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel\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: 0.07 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: 03045961\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51560143716658,"sku":"03045961","price":175.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/137c455a37ac01b3fc29cd42e97c88a2.jpg?v=1786447354","url":"https:\/\/voomisupply.com\/products\/seco-03045961-screw-machine-drill-bit-6mm-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
