It measures 0.316 inches in diameter with a 118-degree faceted point and a standard bright\/uncoated finish. The two-flute, right-hand spiral design runs a regular helix with a web-thinned, parallel-web geometry that reduces entry force and improves chip evacuation. At 2.5 inches overall length with a 1.25-inch straight-cylindrical shank and a 1.25-inch flute length, this bit is sized for screw machine and CNC lathe work where rigidity and short overhang are critical. Licensed machinists and tool-room technicians are the primary users.\u003c\/p\u003e\u003cp\u003eThis Series 206 drill bit is suited for production drilling in cast iron, non-ferrous metals, stainless steel, and carbon steel. The short flute-to-diameter ratio of 3xD makes it a practical choice for high-speed, close-tolerance drilling in automatic screw machines, CNC machining centers, and drill presses where chatter and deflection must be minimized. The solid carbide construction supports higher cutting speeds than high-speed steel alternatives, particularly on abrasive or work-hardening materials such as stainless steel and cast iron.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for elevated cutting speeds and longer tool life on abrasive materials\u003c\/li\u003e\n\u003cli\u003e118-degree faceted point with web-thinned, parallel-web design reduces thrust and improves centering\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, regular spiral flute promotes consistent chip flow in through and blind holes\u003c\/li\u003e\n\u003cli\u003eShort 3xD flute-to-diameter ratio maximizes rigidity and minimizes deflection\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks and collet holders\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish suitable for use with or without cutting fluid on a wide range of workpiece materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in screw machines, CNC lathes, and machining centers with standard drill chucks or collet systems accepting a 0.316-inch straight shank.

Secure the straight-cylindrical shank firmly in a properly sized collet or drill chuck to the depth recommended by the toolholder manufacturer. Verify runout before beginning a production run, as excessive runout accelerates carbide wear and can cause chipping. Follow the machine manufacturer and M.A. FORD recommended speeds and feeds for the specific workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.316 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: O\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.25 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\u003eShank Diameter\u003c\/strong\u003e: 0.316 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Faceted\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel 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\u003eDrill Length Type\u003c\/strong\u003e: Short (Screw Machine)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute-to-Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Cast Iron, Non-Ferrous Metal, Stainless Steel, Steel\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\u003eSeries\u003c\/strong\u003e: 206\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: 20631600\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"M.A. FORD","offers":[{"title":"Default Title","offer_id":51729704026418,"sku":"20631600","price":80.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/01e7b23308cd60a4613f795d9f995e48_42aaf3ae-56a3-4858-ba72-4492d5ad14dd.jpg?v=1788708100","url":"https:\/\/voomisupply.com\/products\/m-a-ford-20631600-screw-machine-drill-bit-0-316-in","provider":"Voomi Supply","version":"1.0","type":"link"}
