Built from solid carbide, it delivers superior hardness and wear resistance compared to high-speed steel alternatives. The drill features a 135-degree split point with web thinning, which reduces thrust force and improves centering on entry without a pilot hole. At 1.8125 inches overall length and 0.0980 inches in diameter (Wire Size 40), this stub-length bit fits compact drilling setups and short-stroke machines. Two spiral flutes with a slow helix control chip evacuation in the materials this bit is engineered for.\u003c\/p\u003e\u003cp\u003eThis drill bit is intended for use in metalworking and machining applications involving cast iron, non-ferrous metals, stainless steel, and carbon steel. The screw machine length format makes it well suited for CNC machining centers, drill presses, and manual screw machines where rigidity and minimal deflection are critical. The straight cylindrical shank seats directly in standard drill chucks and collets. It is a single-margin design with a 3xD flute-to-diameter ratio, providing clearance in shallow-to-moderate depth holes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for hardness and wear resistance in ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003e135-degree web-thinned split point reduces entry thrust and improves self-centering\u003c\/li\u003e\n\u003cli\u003eSlow spiral flute geometry optimized for chip control in cast iron and stainless steel\u003c\/li\u003e\n\u003cli\u003eScrew machine length (1.8125 inches OAL) provides added rigidity over jobber-length bits\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank compatible with standard chucks and collets\u003c\/li\u003e\n\u003cli\u003eTight diameter tolerance of +0.0000 to -0.0005 inches for precision bore sizing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use solid carbide drill bit for metalworking applications requiring Wire Size 40 (0.0980 inch diameter) screw machine length tooling in compatible drill chucks and collets.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and the chuck or collet is clean and undamaged before seating the shank. Solid carbide tooling is brittle  -  avoid side-loading or interrupted cuts that exceed the bit design parameters. Confirm spindle speed and feed rate are appropriate for the workpiece material before beginning the drilling operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 40\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.0980 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.8125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.8125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0980 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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: Slow\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Margins\u003c\/strong\u003e: 1\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\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: 205\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0056 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: 20509800A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"M.A. FORD","offers":[{"title":"Default Title","offer_id":51741649862962,"sku":"20509800A","price":40.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f08e4cc86bc9f13b401ef4fe0fdfc632_10c24ad4-fdb7-463c-8bc9-4993de40e320.jpg?v=1788832725","url":"https:\/\/voomisupply.com\/products\/m-a-ford-20509800a-drill-bit-size-40-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
