Built to Series 204 specifications, it features a 25\/32 inch (0.7812 inch) diameter, a 118-degree faceted point angle, and a 6 inch overall length with a 4 inch spiral flute length. The bright, uncoated carbide construction delivers excellent heat resistance and edge retention. Web thinning reduces thrust load at the point, improving penetration in tough materials. This bit is suited for licensed machinists, tool-and-die professionals, and skilled tradespeople who require consistent hole geometry and tight diameter tolerances.\u003c\/p\u003e\n\u003cp\u003eDesigned as a general-purpose drilling solution, the 20478120 is rated for use in cast iron, non-ferrous metals, stainless steel, and steel. The right-hand, regular spiral flute configuration handles a wide range of workpiece materials across production and job-shop environments. The straight-cylindrical shank is compatible with standard drill chucks found on drill presses, CNC machining centers, and handheld power tools where the chuck capacity allows a 25\/32 inch shank diameter.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for superior hardness and wear resistance versus high-speed steel\u003c\/li\u003e\n  \u003cli\u003e118-degree faceted drill point with web thinning to reduce entry thrust and improve centering\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration with regular spiral flutes for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish compatible with a broad range of workpiece materials without coating buildup concerns\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of -0.0005 to 0.0000 inch for consistent, close-tolerance hole sizing\u003c\/li\u003e\n  \u003cli\u003eManufactured under ISO 9001:2015 certified quality standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for primary workpiece materials including cast iron, non-ferrous metal, stainless steel, and steel (material codes K, M, N, and P).

Secure the workpiece firmly before drilling, and confirm the drill press or machine spindle is fully powered down before inserting or removing the bit. Carbide tooling is brittle compared to high-speed steel and should not be subjected to lateral shock loads or dropped onto hard surfaces. Verify chuck runout and clamping force before use to protect the shank and maintain hole-location accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 25\/32 inch (0.7812 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 4 inches\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\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Bright\/Uncoated\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 25\/32 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0005 to 0.0000 inch\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: 204\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance Grade\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ISO 9001:2015 Certified\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\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: 20478120\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"M.A. FORD","offers":[{"title":"Default Title","offer_id":51739846115634,"sku":"20478120","price":494.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3443583573f8dad1c3555b01a59849af_2c2aca28-d0dd-4f55-acea-7c1abffa2eeb.jpg?v=1788819560","url":"https:\/\/voomisupply.com\/products\/m-a-ford-20478120-carbide-drill-bit-25-32-in-118-deg","provider":"Voomi Supply","version":"1.0","type":"link"}
