Built to DIN 6539 specification, this short-length bit measures 0.2559 inches (6.50 mm) in diameter with an overall length of 2.7559 inches (70.00 mm). The 118-degree faceted drill point paired with a web-thinned, parallel web configuration reduces entry thrust and improves chip clearing on hard materials. The bright\/uncoated finish makes it well-suited for non-ferrous metals where coating adhesion or heat are not concerns. Two spiral flutes with a 3xD flute-to-diameter ratio evacuate chips efficiently during short, high-precision drilling operations. This bit is installed by machinists, toolmakers, and maintenance technicians.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is intended for use in CNC machining centers, drill presses, and manual mills where screw machine length geometry provides added rigidity and reduced runout. Primary workpiece materials include cast iron, non-ferrous metal, stainless steel, and steel. The straight-cylindrical shank measures 0.2559 inches in diameter and 1.5354 inches in length, making it compatible with standard collet chucks and drill chucks in that bore range. The right-hand cut and regular spiral flute type suit general-purpose production drilling and maintenance applications where tight tolerances and consistent hole quality are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\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 reduces thrust and improves self-centering\u003c\/li\u003e\n  \u003cli\u003eScrew machine (short) length geometry provides increased rigidity and minimizes deflection\u003c\/li\u003e\n  \u003cli\u003eDIN 6539 specification for consistent dimensional conformance\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of +0.0000 to -0.0005 inches ensures precise hole sizing\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through design simplifies setup in standard spindle configurations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard straight-shank drill chucks and collet systems accepting a 0.2559-inch shank diameter.

Ensure the spindle and workpiece are fully secured before engaging the drill. Solid carbide tooling is brittle and should not be subjected to side loads, interrupted cuts without appropriate feed rates, or improper chuck grip. Inspect the shank seating and runout before production use to avoid premature tool failure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.2559 inches (6.50 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.7559 inches (70.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 31.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2559 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.5354 inches (39.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute-to-Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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: Parallel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0005 inches\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\u003eSeries\u003c\/strong\u003e: 226\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: DIN 6539\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 22625590\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"M.A. FORD","offers":[{"title":"Default Title","offer_id":51729037492530,"sku":"22625590","price":73.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2f50e45c19c859b24d81a857040eea28.jpg?v=1788699132","url":"https:\/\/voomisupply.com\/products\/m-a-ford-22625590-screw-machine-drill-bit-0-2559-in","provider":"Voomi Supply","version":"1.0","type":"link"}
