It measures 0.2210 inches in diameter (Wire Size 2) with a 145-degree drill point angle and an AlTiN coating for extended tool life and heat resistance. The overall length is 2.625 inches, making it a compact, stub-length tool suited for applications where reach is limited and rigidity is critical. Licensed machinists and tooling technicians rely on this bit when drilling tight-tolerance holes in hard alloys, titanium, and similar high-strength materials where tool deflection and heat buildup are primary concerns.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is intended for use in CNC machining centers, drill presses, and manual machine tools where screw machine length geometry provides added stability. It is well-suited for production environments drilling alloy steels and titanium alloys. The web-thinned, tapered web configuration reduces thrust load at entry, improving hole quality and reducing the risk of workpiece deformation. It is a practical choice for job shops and aerospace or industrial manufacturing operations requiring consistent, repeatable results in difficult-to-machine materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard-material drilling\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating provides heat and oxidation resistance, extending tool life in dry or semi-dry cutting conditions\u003c\/li\u003e\n  \u003cli\u003e145-degree split point angle reduces walking and improves penetration without a center punch\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web lowers thrust requirements and improves chip evacuation\u003c\/li\u003e\n  \u003cli\u003eScrew machine length (2.625 inches OAL) delivers greater rigidity compared to jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of +0.0002 to +0.0006 inches supports tight-tolerance hole sizing\u003c\/li\u003e\n  \u003cli\u003eMaximum drilling depth of 0.8281 inches with a flute-to-diameter ratio of 3xD\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard production drill bit for use in straight-shank chuck systems on CNC machining centers, drill presses, and manual mills requiring a 0.2210-inch diameter screw machine length bit.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis bit is installed and operated by qualified machinists or tooling technicians. Secure the straight cylindrical shank firmly in a drill chuck or collet rated for the spindle speed appropriate to the workpiece material and bit diameter. Ensure the machine is fully powered down and spindle is locked before changing tooling. Do not exceed the recommended maximum drilling depth of 0.8281 inches per pass without retracting to clear chips.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.2210 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.4375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.8281 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 145 degrees\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\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: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Margins\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\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\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0002 to +0.0006 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Alloy, Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 135\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: SGS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 51781\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51730955632946,"sku":"51781","price":194.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1f76b44f7e34536204d68c01d9f26669_ed57af61-9c91-49cd-9498-f99b5182f12f.jpg?v=1788725265","url":"https:\/\/voomisupply.com\/products\/sgs-51781-carbide-screw-machine-drill-bit-0-2210-in","provider":"Voomi Supply","version":"1.0","type":"link"}
