Built from solid carbide with a TiAlN coating, it delivers superior wear resistance and heat tolerance compared to high-speed steel tooling. The 140-degree cone relief point geometry promotes accurate entry and reduced thrust force. At 11.00 mm in diameter with an overall length of 102.00 mm (approximately 4.02 inches), this bit fits standard straight-shank tool holders and is suited for CNC machining centers, drill presses, and automated production cells. It is typically installed and operated by machinists and tooling professionals.\u003c\/p\u003e\u003cp\u003eThis drill bit is intended for right-hand cutting in steel and similar primary workpiece materials. The screw machine length format provides added rigidity over jobber-length bits, making it appropriate for close-tolerance through-hole and blind-hole drilling where runout and deflection must be minimized. The SD203A series targets high-volume production applications where consistent hole quality and tool life are priorities. Coolant-through capability supports chip evacuation and thermal management during extended cutting cycles at aggressive feed and speed parameters.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with TiAlN proprietary coating for extended tool life in steel applications\u003c\/li\u003e\n\u003cli\u003e140-degree cone relief point for accurate self-centering and reduced thrust on entry\u003c\/li\u003e\n\u003cli\u003eCoolant-through design aids chip evacuation and controls cutting-zone temperature\u003c\/li\u003e\n\u003cli\u003eWeb-thinned geometry lowers cutting resistance and improves penetration efficiency\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank (12.00 mm diameter) fits standard collets and drill chucks without modification\u003c\/li\u003e\n\u003cli\u003eRegular spiral flute with 3xD flute-to-diameter ratio balances chip flow and rigidity\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style production drill bit in the SECO SD203A series, compatible with straight-shank tool holders and collet chucks accepting a 12.00 mm shank diameter.

Ensure the machine spindle and tool holder are clean and free of chips before seating the shank. Confirm coolant-through passages are clear and coolant pressure is set per machine specifications before initiating a cut. Do not exceed the maximum drilling depth of 40.00 mm per pass without retracting to clear chips.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 11.00 mm (0.4331 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 102.00 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\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 2.00 mm\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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Cone Relief\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\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\u003eCoating\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel\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\u003eStandard\u003c\/strong\u003e: DIN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: SD203A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.243 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: 03046010\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51559018660146,"sku":"03046010","price":338.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2b9771df910979caae79718acfd119dd_c6684b0f-a4d6-4645-b5f6-02d4c2c296d6.jpg?v=1786425890","url":"https:\/\/voomisupply.com\/products\/seco-03046010-drill-bit-11mm-solid-carbide-tialn-sd203a","provider":"Voomi Supply","version":"1.0","type":"link"}
