Manufactured in Series 204, it features a bright\/uncoated finish, a straight cylindrical shank, and a regular spiral flute configuration. The 4-facet point reduces walking at entry and improves chip evacuation compared to standard conical geometry. With an overall length of 4.5 inches and a flute length of 2.875 inches, this drill is sized for general-purpose production and maintenance drilling in metal fabrication, machining, and mechanical assembly environments.\u003c\/p\u003e\u003cp\u003eThis bit is engineered for drilling steel, aluminum, and non-ferrous materials. Its 5xD flute-to-diameter ratio and web-thinned construction make it well suited for through-hole drilling on drill presses, CNC machining centers, and hand-held power tools where consistent hole quality in ferrous and non-ferrous stock is required. Right-hand cutting direction is standard. Coolant-through capability is not available on this model.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and extended tool life in metal drilling applications\u003c\/li\u003e\n\u003cli\u003e118-degree 4-facet point for reduced walking and improved self-centering at entry\u003c\/li\u003e\n\u003cli\u003eWeb-thinned design reduces thrust force and aids chip evacuation\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish suitable for use with cutting fluids on steel and non-ferrous alloys\u003c\/li\u003e\n\u003cli\u003eRegular spiral flute with 5xD ratio provides efficient chip flow in through-hole drilling\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of +0.0000 to -0.0005 inches for consistent, accurate hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose jobber drill for use in drill presses, CNC machining centers, and power hand tools where a Letter X straight-shank carbide bit is required for drilling steel, aluminum, and non-ferrous materials.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by machinists or qualified mechanical trades familiar with carbide tooling. Secure the straight shank fully in a compatible chuck or collet before operation to prevent runout that can chip carbide. Always verify spindle speed and feed rate are appropriate for the workpiece material and drill diameter before engaging the cut. Carbide drill bits are brittle and should not be used in applications involving significant lateral loading or interrupted cuts without engineering review.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: X\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.3970 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: 4 Facet\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\u003eFlute Type\u003c\/strong\u003e: Regular Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.875 inches (2-7\/8 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.5 inches (4-1\/2 inches)\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: 0.3970 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: 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: +0.0000 to -0.0005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Aluminum, Non-Ferrous\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 204\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO 9001:2015 Certified\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1998 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: 20439700\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"M.A. FORD","offers":[{"title":"Default Title","offer_id":51743270666546,"sku":"20439700","price":177.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3443583573f8dad1c3555b01a59849af_1afb5231-9892-4dee-be1f-a9dc1f40e7d2.jpg?v=1788844824","url":"https:\/\/voomisupply.com\/products\/m-a-ford-20439700-solid-carbide-jobber-drill-letter-x","provider":"Voomi Supply","version":"1.0","type":"link"}
