The bit features a 118-degree faceted point angle with web thinning for improved penetration and reduced thrust force at entry. A regular spiral flute with a 5xD flute-to-diameter ratio clears chips efficiently during through-hole and blind-hole drilling. The straight cylindrical shank and 1.75-inch overall length make it compatible with standard drill chucks and collet holders. This bit ships uncoated (bright finish) and carries ISO 9001:2015 certification.\u003c\/p\u003e\u003cp\u003eThis drill bit is rated for general-purpose drilling in a wide range of workpiece materials including cast iron, non-ferrous metals, stainless steel, and carbon steel. It is well suited for precision production drilling, toolroom work, and MRO applications where tight hole tolerances are required. The diameter tolerance of -0.0005 to 0.0000 inches ensures consistent, close-tolerance holes. Machinists, tool and die makers, and maintenance technicians working with small-diameter fastener clearance holes or tapping operations will find this bit appropriate for CNC or manual drill press use.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003e118-degree faceted drill point with web thinning reduces entry thrust and improves centering\u003c\/li\u003e\n\u003cli\u003eRegular spiral flute, 5xD ratio, promotes efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of -0.0005 to 0.0000 inches for repeatable close-tolerance holes\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank fits standard drill chucks and ER collets\u003c\/li\u003e\n\u003cli\u003eISO 9001:2015 certified manufacturing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose solid carbide jobber drill for use in CNC machining centers, drill presses, and manual machines equipped with standard straight-shank collets or chucks accepting a 0.0785-inch shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eSolid carbide tooling should be installed and removed with the machine fully powered down and spindle locked. Ensure the chuck or collet is clean and free of debris before seating the straight shank to prevent runout. Carbide is brittle compared to high-speed steel  -  avoid side loading, interrupted cuts at excessive feed rates, or re-chucking with worn collets. No coolant-through capability on this bit; apply flood or mist coolant externally when drilling stainless steel or cast iron at sustained speeds.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: No. 47\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0785 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\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: Tapered, Web-Thinned\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: Regular Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0785 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0005 to 0.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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\u003eTool Performance Grade\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 204\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ISO 9001:2015 Certified\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: 20407850\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"M.A. FORD","offers":[{"title":"Default Title","offer_id":51743360155954,"sku":"20407850","price":32.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3443583573f8dad1c3555b01a59849af_e81c9258-60d9-4192-bbe9-9f7b2314103a.jpg?v=1788846138","url":"https:\/\/voomisupply.com\/products\/m-a-ford-20407850-carbide-drill-bit-no-47-0-0785-in","provider":"Voomi Supply","version":"1.0","type":"link"}
