Built from solid carbide, this bit delivers superior wear resistance and heat tolerance compared to high-speed steel alternatives. It features a 140-degree standard point angle with web thinning for reduced thrust and cleaner entry, and a straight-cylindrical shank measuring 0.3937 inches in diameter. The overall length is 3.50 inches (89 mm), making it well suited for short-reach, high-rigidity setups on CNC machining centers, drill presses, and screw machines. Coolant-through construction supports extended tool life in production environments.\u003c\/p\u003e\u003cp\u003eThis drill bit is intended for use in production machining operations where tight tolerances and consistent hole quality are required. The SD1103A series is a universal-performance tool appropriate for a wide range of workpiece materials. Its screw machine length profile keeps the tool compact and rigid, reducing deflection in close-clearance fixtures and multi-spindle setups. Machinists and tool-and-die professionals working in job shops, production lines, or maintenance environments will find this bit suitable for standard drilling cycles at moderate to high feed rates.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for extended tool life and heat resistance\u003c\/li\u003e\n\u003cli\u003e140-degree standard point angle with web thinning for reduced entry thrust\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports high-feed production drilling\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute with 2-flute geometry for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eScrew machine length (3.50 inches OAL) provides maximum rigidity in short-reach applications\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks and collet holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use screw machine length drill bit suitable for CNC machining centers, drill presses, and multi-spindle screw machines accepting a straight-cylindrical shank of 0.3937 inches diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified machinists familiar with cutting tool setup and machine operation. Secure the shank fully within the collet or chuck before initiating a cut, and verify spindle runout is within acceptable tolerance for the application. Ensure coolant flow is confirmed before starting coolant-through drilling cycles to prevent premature tool failure. Follow machine manufacturer guidelines and applicable shop safety standards when changing or setting tooling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.50 inches (89 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 47 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3937 inches (10 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.57 inches (40 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\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\u003eMaximum Drilling Depth\u003c\/strong\u003e: 35 mm\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\u003eSeries\u003c\/strong\u003e: SD1103A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter 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\u003eWeight\u003c\/strong\u003e: 0.16 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: 02898331\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51558936510770,"sku":"02898331","price":173.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b21d2d7552bd462a2063d7fb306aa31e_41a24070-3a6d-4a6a-9aeb-0ec48c3e94d7.jpg?v=1786423400","url":"https:\/\/voomisupply.com\/products\/seco-02898331-screw-machine-drill-bit-3-8-in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
