Built from solid carbide, it delivers the rigidity and wear resistance needed for high-speed, short-hole drilling applications. The bit measures 0.1875 inches (3\/16 inch) in diameter with an overall length of 2.1875 inches and a flute length of 0.9375 inches. A bright\/uncoated finish and fast spiral flute geometry promote efficient chip evacuation. The straight-cylindrical shank seats directly in standard drill chucks or collets. This is a Series 207 bit with a web-thinned, parallel web configuration for reduced thrust at entry.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for production and maintenance drilling in non-ferrous metals, plastics, and composite materials where a compact screw machine length provides improved rigidity over jobber-length bits. The 3xD flute-to-diameter ratio keeps the bit stiff in short-hole operations, making it a practical choice for CNC machining centers, drill presses, and manual screw machine setups. Machinists and tool-and-die professionals working in high-precision environments will find the tight diameter tolerance of +0.0000 to -0.0005 inches useful for held-size drilling without reaming.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for extended tool life in non-ferrous metal drilling\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish, right-hand cut with fast spiral flute for efficient chip removal\u003c\/li\u003e\n\u003cli\u003eScrew machine (stub) length at 2.1875 inches overall for improved rigidity\u003c\/li\u003e\n\u003cli\u003eTight diameter tolerance of +0.0000 to -0.0005 inches for precision bore sizing\u003c\/li\u003e\n\u003cli\u003eWeb-thinned parallel web reduces entry thrust and improves centering\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank compatible with standard chucks and collets\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-application solid carbide screw machine drill bit for use in standard drill chucks, collet systems, and CNC toolholders accepting a 0.1875-inch straight-cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use of carbide drill bits should be performed by qualified machinists or tool technicians familiar with proper speeds, feeds, and clamping procedures for the workpiece material. Ensure the machine spindle and toolholder are powered down and locked out before bit changes. Inspect the shank and chuck bore for contamination or damage before seating the bit. Carbide is brittle — avoid side loading, interrupted cuts without proper setup, or dropping the bit on hard surfaces.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.1875 inches (3\/16 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.1875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.9375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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: Fast\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel Web-Thinned\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Non-Ferrous Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 207\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: M.A. FORD.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 20718750\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"M.A. FORD","offers":[{"title":"Default Title","offer_id":51734877831474,"sku":"20718750","price":73.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7c86099f2db78e93537937958f9f2ade.jpg?v=1788767524","url":"https:\/\/voomisupply.com\/products\/m-a-ford-20718750-screw-machine-drill-bit-3-16-in","provider":"Voomi Supply","version":"1.0","type":"link"}
