Ford 40431250 Solid Carbide Spotting Drill 5\/16 in","description":"\u003ch3\u003eProduct Description\u003c\/h3\u003e\n\u003cp\u003eThe M.A. FORD 40431250 is a solid carbide spotting drill designed to accurately locate and start holes before a twist or jobber drill follows through. Built to a 90-degree point angle, it produces a clean, precise cone seat that guides subsequent drilling operations and reduces walkout on flat or angled workpiece surfaces. The 5\/16 inch cutting diameter and 2.5 inch overall length suit a wide range of part sizes and machine setups. With two spiral flutes and a 21-degree helix angle, the tool evacuates chips efficiently during the spotting pass. The bright, uncoated finish makes the carbide substrate visible for inspection and suits general-purpose applications where coating is not required.\u003c\/p\u003e\n\u003cp\u003eThis spotting drill is used in machine shops and production environments running CNC machining centers, drill presses, or manual knee mills. It is suited for general-purpose spotting on ferrous and non-ferrous materials where a 90-degree countersink seat is required before through-hole or tapped-hole drilling. The straight cylindrical shank fits standard ER collet chucks and drill chucks without adapters, making tool changes fast on typical spindle setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e90-degree point angle creates an accurate locating cone for standard twist drills\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction provides rigidity and wear resistance over high-cycle use\u003c\/li\u003e\n  \u003cli\u003eTwo spiral flutes with 21-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suitable for general-purpose spotting across common workpiece materials\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank compatible with standard collet and drill chuck toolholding\u003c\/li\u003e\n  \u003cli\u003eSingle-ended design, Series 404\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose spotting drill for use in any machine spindle accepting a 5\/16 inch straight cylindrical shank.

Secure the shank fully in the collet or drill chuck to the manufacturer-recommended engagement depth before running the spindle. Set spindle speed and feed rate per the material and tool diameter being spotted. Inspect the cutting edges for chipping before each use, as carbide is brittle and can micro-chip if dropped or mishandled.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 5\/16 inch (0.3125 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1 inch (1.0000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/16 inch (0.3125 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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 21 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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle\/Double Ended\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 404\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: 40431250\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"M.A. FORD","offers":[{"title":"Default Title","offer_id":51749966151986,"sku":"40431250","price":80.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/265d5d841c4ec9ebc74673e3fe6c5972.jpg?v=1788912725","url":"https:\/\/voomisupply.com\/products\/m-a-ford-40431250-solid-carbide-spotting-drill-5-16-in","provider":"Voomi Supply","version":"1.0","type":"link"}
