Ford 61050004 Single Flute Countersink 100 Degree Hss","description":"\u003ch3\u003eProduct Description\u003c\/h3\u003e\u003cp\u003eThe M.A. FORD 61050004 is a single-flute, high-speed steel countersink designed for chamfering, countersinking, and deburring operations in a wide range of materials. It features a 100-degree included angle and a 0.5-inch head diameter, making it well suited for standard fastener seat preparation. The straight cylindrical shank measures 0.25 inches in diameter and the tool runs to an overall length of 2 inches. A bright, uncoated finish keeps the tool ready to use out of the package without additional prep. Machinists and toolroom technicians reach for this type of single-flute countersink when a clean, chatter-free entry is needed on softer and harder metals alike.\u003c\/p\u003e\u003cp\u003eThis countersink is used in machine shops, maintenance facilities, and production environments where precise fastener seating or edge preparation is required. Its single-flute geometry reduces chatter on hand-held and machine-spindle applications. The tool accepts a standard 0.25-inch collet or drill chuck and fits bench-top drill presses, milling machines, and hand drills. It is not piloted, so the operator controls centering. Applications span chamfering screw holes, deburring drilled edges, and preparing countersunk fastener seats on flat and curved workpiece surfaces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e100-degree included angle for standard countersunk fastener seating\u003c\/li\u003e\n\u003cli\u003eSingle flute design minimizes chatter and produces a clean finish\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction supports use across a broad range of workpiece materials\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish — no coating removal needed before use\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank fits standard 0.25-inch collets and drill chucks\u003c\/li\u003e\n\u003cli\u003eNo pilot — allows flexible positioning on the workpiece\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style single-flute countersink compatible with drill presses, CNC mills, and hand-held drills accepting a 0.25-inch straight shank.

Secure the workpiece before engaging the tool; countersinking unsecured parts is a recognized safety hazard. For hand-drill use, start at a low speed to establish the countersink location before increasing RPM. Inspect the cutting edge before each use and replace the tool if chipping or dullness is observed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 100 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenterline Angle\u003c\/strong\u003e: 50 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip\/Nose Diameter\u003c\/strong\u003e: 0.060 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 Material\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes Pilot\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Chamfering, Countersinking, Deburring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Alloy Steel, Aluminum, Brass, Cast Iron, High-Nickel Steel, High-Tensile Steel, Magnesium, Magnesium Alloy, Mild Steel, Monel, Plastic, Stainless Steel\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: 61050004\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"M.A. FORD","offers":[{"title":"Default Title","offer_id":51750280462642,"sku":"61050004","price":34.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b292c87f2cf827489dd02b7ac5b03192.jpg?v=1788914627","url":"https:\/\/voomisupply.com\/products\/m-a-ford-61050004-single-flute-countersink-100-degree-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
