It features a 118-degree four-facet point ground to a web-thinned geometry for reduced thrust and cleaner entry. The ALtima and Titanium Nitride (TiN) dual coating improves surface hardness, lubricity, and tool life compared to uncoated carbide. Overall length is 1.75 inches with a 0.875-inch flute length. Right-hand spiral flutes with a regular spiral type handle chip evacuation efficiently. This drill is suited for machinists, tool-and-die technicians, and production drilling operations where tight tolerances and consistent hole quality are required.\u003c\/p\u003e\u003cp\u003eThis drill bit is built for general-purpose production and maintenance drilling in cast iron, non-ferrous metals, stainless steel, and carbon steel. The small diameter and jobber-length format make it well suited for precision hole-making in fixtures, assemblies, and fabricated components. The straight-cylindrical shank seats directly in standard drill chucks and collet holders without adapters. It is part of M.A. FORD. Series 204, a line of small-diameter solid carbide drills engineered for repeatable performance in short-run and high-cycle applications alike.\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 workpiece materials\u003c\/li\u003e\n\u003cli\u003eALtima and TiN dual coating extends tool life and reduces built-up edge on non-ferrous and stainless applications\u003c\/li\u003e\n\u003cli\u003e118-degree four-facet point with web thinning reduces entry thrust and improves centering accuracy\u003c\/li\u003e\n\u003cli\u003eRight-hand regular spiral flutes promote efficient chip evacuation in through and blind holes\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of +0.0000 to -0.0005 inches supports consistent close-tolerance hole sizing\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard drill chucks and collet holders without modification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style general-purpose jobber drill for use in any standard drill press, CNC machining center, or hand-held drill equipped with a chuck or collet capable of accepting a 0.0785-inch straight shank.

Secure the shank fully in the chuck or collet and verify runout before drilling, as carbide is brittle and sensitive to lateral loading. Coolant-through is not supported on this drill; apply cutting fluid externally when drilling stainless steel or cast iron to manage heat and extend tool life. Avoid using this drill in impact drivers or hammer-drill mode, which will fracture the carbide substrate.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 47\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\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\u003eCoating\/Finish\u003c\/strong\u003e: ALtima \/ Titanium Nitride (TiN)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Four Facet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\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\u003eFlute Length\u003c\/strong\u003e: 0.875 inches (7\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.75 inches (1-3\/4 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: +0.0000 to -0.0005 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\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\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\u003eStandards\u003c\/strong\u003e: ISO 9001:2015 Certified\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0033 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: M.A. FORD.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 20407850A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"M.A. FORD","offers":[{"title":"Default Title","offer_id":51743937823026,"sku":"20407850A","price":36.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3443583573f8dad1c3555b01a59849af_3191eb98-2638-465a-8351-fbd778b34cb8.jpg?v=1788851591","url":"https:\/\/voomisupply.com\/products\/m-a-ford-20407850a-jobber-drill-no-47-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
