Ford 20505110 Carbide Screw Machine Drill Bit","description":"\u003ch3\u003eProduct Description\u003c\/h3\u003e\u003cp\u003eThe M.A. FORD 20505110 is a solid carbide screw machine length drill bit with a 0.0511 inch (1.30 mm) diameter and a 135-degree split point. Screw machine length drills are shorter than jobber-length bits, which improves rigidity and reduces deflection in close-tolerance drilling applications. The bright, uncoated carbide construction delivers excellent hardness and heat resistance without a coating that could alter the cutting edge geometry. Web thinning reduces thrust force at the cutting tip. This bit is suited for machinists, toolroom technicians, and CNC operators working with small-diameter holes in hard materials.\u003c\/p\u003e\u003cp\u003eThis drill bit is designed for use on cast iron, non-ferrous metals, stainless steel, and steel. The slow spiral flute design and right-hand cut make it well suited for drilling tough, stringy, or work-hardening materials where chip evacuation and heat control are critical. Its short overall length of 1.6142 inches and straight-cylindrical shank allow use in standard drill chucks, collets, and CNC toolholders. Typical applications include production drilling, precision machining, and toolroom work where hole location accuracy and drill longevity are priorities.\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\u003e135-degree split point reduces walking and lowers required thrust force at entry\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tip for reduced cutting resistance in hard materials\u003c\/li\u003e\n\u003cli\u003eSlow spiral flute geometry improves chip control in stainless steel and cast iron\u003c\/li\u003e\n\u003cli\u003eScrew machine (stub) length increases rigidity and minimizes deflection\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish preserves as-ground cutting edge geometry\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard drill chucks, ER collets, and CNC toolholders accepting a 0.0511 inch straight-cylindrical shank.

Ensure the spindle is powered down and locked out before mounting or removing the drill bit from any holder. Verify collet or chuck runout before use, as excessive runout will accelerate wear on small-diameter carbide tooling. Carbide is brittle  -  avoid impact or side-loading, and store individually to prevent chipping the cutting edges.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.0511 inches (1.30 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.6142 inches (41.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0511 inches (1.30 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 0.9843 inches (25.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.6299 inches (16.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\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, Slow\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute-to-Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.000 to -0.013 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\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: 0.0014 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 20505110\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"M.A. FORD","offers":[{"title":"Default Title","offer_id":51743002132786,"sku":"20505110","price":32.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f08e4cc86bc9f13b401ef4fe0fdfc632_a0715295-8180-4020-b275-9ecc1762f169.jpg?v=1788841430","url":"https:\/\/voomisupply.com\/products\/m-a-ford-20505110-carbide-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
