Ford 79050006 Countersink 120 Deg 6 Flute Hss 1\/2 in","description":"\u003ch3\u003eProduct Description\u003c\/h3\u003e\n\u003cp\u003eThe M.A. FORD 79050006 is a 6-flute, single-end countersink designed for chamfering, countersinking, and deburring operations in metal fabrication and machining environments. Built from high-speed steel (HSS) with a bright\/uncoated finish, it features a 120-degree included angle (60-degree centerline angle) and a 1\/2-inch head diameter. The straight-cylindrical shank measures 3\/8 inches in diameter, and the tool runs 2 inches in overall length. Right-hand cutting direction suits standard spindle rotation on mills, drill presses, and lathes. Licensed machinists, tool and die makers, and fabrication shops are the primary users of this tool.\u003c\/p\u003e\n\u003cp\u003eThis countersink is suited for production and maintenance applications across a wide range of workpiece materials. The 120-degree geometry is commonly used when a shallower chamfer angle is required on fastener seats or edge breaks. Typical applications include countersinking clearance holes in sheet metal, structural steel, aluminum plate, and plastic components prior to fastener installation. The 6-flute configuration reduces chatter and produces a smoother finish compared to single- or double-flute designs at similar feed rates.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e120-degree included angle for shallow-seat countersinking and chamfering\u003c\/li\u003e\n  \u003cli\u003e6 flutes for reduced chatter and improved surface finish\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction handles alloy steel, stainless steel, cast iron, brass, aluminum, magnesium alloy, Monel, and plastic\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish  -  no coating buildup concerns when running cutting fluid\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical 3\/8-inch shank fits standard drill chuck and collet holders\u003c\/li\u003e\n  \u003cli\u003eSingle-end design, no pilot  -  requires center-punched or pre-drilled pilot hole\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for use on alloy steel, aluminum, brass, cast iron, high-nickel steel, high-tensile steel, magnesium, magnesium alloy, mild steel, Monel, plastic, and stainless steel workpieces.

Always secure the workpiece firmly before operation and confirm spindle speed matches the material and head diameter per standard HSS cutting data tables. Because this countersink includes no pilot, a pre-drilled or center-punched pilot hole is required to locate the tool accurately. Apply cutting fluid appropriate to the workpiece material when machining ferrous metals to extend tool life.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 120 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenterline Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\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: 3\/8 inch\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: 0.150 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\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\u003eUNSPSC Code\u003c\/strong\u003e: 27112812\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: 79050006\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"M.A. FORD","offers":[{"title":"Default Title","offer_id":51742745100594,"sku":"79050006","price":36.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0b3820ef0bc7c921398be4b6b3eafe86.jpg?v=1788839239","url":"https:\/\/voomisupply.com\/products\/m-a-ford-79050006-countersink-120-deg-6-flute-hss-1-2-in","provider":"Voomi Supply","version":"1.0","type":"link"}
