Built from solid carbide, it features a 140-degree point angle with web thinning for reduced thrust and cleaner entry. The bit measures 12.9 mm in diameter with an overall length of 107 mm (4.21 inches) and a flute length of 60 mm. A straight-cylindrical shank with a 14 mm diameter ensures secure chuck engagement. Coolant-through capability makes this bit well-suited for high-speed or deep-hole drilling operations where heat management is critical. It is part of the SD1103A series and conforms to DIN standards.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is intended for use in CNC machining centers, drill presses, and screw machine setups where shorter flute-to-diameter ratios improve rigidity and hole quality. The 3xD flute-by-diameter ratio and universal tool performance rating make it appropriate across a range of workpiece materials. Right-hand cut with a spiral flute geometry supports efficient chip evacuation. Machinists and tool-and-die professionals working in production environments will find the web-thinned point reduces walking and improves concentricity on entry. Maximum drilling depth is 43 mm.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in demanding machining environments\u003c\/li\u003e\n  \u003cli\u003e140-degree point angle with web thinning reduces entry thrust and minimizes bit walking\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports effective heat dissipation during high-feed or deep drilling\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank at 14 mm diameter for reliable chuck or collet holding\u003c\/li\u003e\n  \u003cli\u003eScrew machine length (3xD flute ratio) provides added rigidity over jobber-length alternatives\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN standards; UNSPSC Code 23241635\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit tooling option for screw machine and CNC drilling setups requiring a 12.9 mm solid carbide drill bit with a straight-cylindrical shank in the SD1103A series.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or toolroom technicians. Ensure the machine spindle is fully stopped and locked out before changing tooling. Confirm chuck or collet bore matches the 14 mm shank diameter to prevent runout. When using the coolant-through feature, verify that the machine's internal coolant system is properly pressurized and connected before beginning the drilling cycle.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 12.9 mm (0.5079 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 107 mm (4.21 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 60 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 43 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 14 mm (0.5512 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 45 mm (1.77 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 2.30 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 140 degrees\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\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\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\u003eTool Performance\u003c\/strong\u003e: Universal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: m7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: DIN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: SD1103A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.35 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: SECO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 02898371\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51557928698162,"sku":"02898371","price":338.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b21d2d7552bd462a2063d7fb306aa31e_d6e73542-a19d-48d3-90fc-9b7bf086de06.jpg?v=1786398653","url":"https:\/\/voomisupply.com\/products\/seco-02898371-screw-machine-drill-bit-12-9mm-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
