Designed for short-reach drilling applications where rigidity and precision matter, it features a 118-degree faceted point angle with web thinning for reduced thrust at entry. The two-flute spiral design in a right-hand cut configuration delivers efficient chip evacuation. With a bright\/uncoated finish and a parallel web construction, this bit is built for shops and machinists running high-precision production or maintenance drilling on hard and abrasive workpiece materials.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for drilling cast iron, non-ferrous metals, stainless steel, and steel. The screw machine length format keeps the tool short and stiff, making it a preferred choice for CNC machining centers, drill presses, and manual machines where chatter and deflection must be minimized. The straight-cylindrical shank fits standard drill chucks without an adapter. It is appropriate for toolroom use, production machining, and maintenance repair operations requiring tight diameter tolerances.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for superior hardness and wear resistance in ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003e118-degree faceted drill point with web thinning for reduced entry thrust and self-centering performance\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish suitable for use with or without coolant on a wide range of materials\u003c\/li\u003e\n\u003cli\u003eShort stub length at 2.75 inches overall reduces deflection and improves hole accuracy\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of +0.0000 to -0.0005 inches for precision bore sizing\u003c\/li\u003e\n\u003cli\u003eTwo spiral flutes with regular helix for consistent chip clearance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a Series 206 screw machine length solid carbide drill bit for use in applications requiring Letter Y (0.4040-inch) diameter holes in cast iron, non-ferrous metal, stainless steel, and steel workpieces.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified machinists or tool and die professionals familiar with carbide tooling. Secure the straight-cylindrical shank firmly in a compatible drill chuck or collet before operation. Solid carbide tooling is brittle — avoid side loading, interrupted cuts without proper setup, or dropping the tool. Verify spindle speed and feed rate are appropriate for the workpiece material and machine before starting.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: Y\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.404 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\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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\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: 0.404 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.75 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: 1.5 inches\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: Short (Screw Machine Length)\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\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Cast Iron, Non-Ferrous Metal, Stainless Steel, Steel\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: 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: 20640400\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"M.A. FORD","offers":[{"title":"Default Title","offer_id":51747642212658,"sku":"20640400","price":115.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/01e7b23308cd60a4613f795d9f995e48_bd2f24c6-e48a-4866-9803-4cee07bf4de5.jpg?v=1788883968","url":"https:\/\/voomisupply.com\/products\/m-a-ford-20640400-screw-machine-drill-bit-0-404-in","provider":"Voomi Supply","version":"1.0","type":"link"}
