Built from high-speed steel with a bright uncoated finish, it features a 60-degree included angle and a straight cylindrical shank measuring 0.25 inches in diameter. The overall length is 2 inches, making it a compact tool suited for benchtop drill presses, CNC machines, and hand drilling setups. Right-hand cutting direction is standard. Machinists, tool and die workers, and general fabricators use this countersink for precise seat preparation and edge cleanup across a wide range of materials.\u003c\/p\u003e\u003cp\u003eThis countersink is well suited for light to medium-duty shop work involving both ferrous and non-ferrous materials. The 60-degree included angle is commonly used for fastener seat preparation in standard machine screw applications. With a head diameter of 0.3125 inches and a tip nose diameter of 0.08 inches, it handles fine countersinking work in confined areas. It does not include a pilot and is sold as a head-only tool, meaning it relies on operator technique or a fixture for center alignment during use.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e60-degree included angle for standard fastener seat and chamfer profiles\u003c\/li\u003e\n\u003cli\u003e6-flute geometry provides smooth cutting action and improved chip evacuation\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction handles a broad range of workpiece materials\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for general-purpose shop use\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical 0.25-inch shank fits standard drill chucks and collets\u003c\/li\u003e\n\u003cli\u003eSingle-end design with no pilot for flexible positioning\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible workpiece materials include alloy steel, aluminum, brass, cast iron, high-nickel steel, high-tensile steel, magnesium, magnesium alloy, mild steel, Monel, plastic, and stainless steel.

Before mounting, ensure the spindle is fully stopped and the chuck key is removed from the chuck. Secure the shank fully in the chuck or collet to the recommended grip depth to prevent runout. Feed rate and spindle speed should be selected according to workpiece material hardness and tool diameter to avoid overheating the cutting edges.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 0.3125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenterline Angle\u003c\/strong\u003e: 30 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: 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: 0.08 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\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\u003eUNSPSC Code\u003c\/strong\u003e: 27112812\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: 79031201\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"M.A. FORD","offers":[{"title":"Default Title","offer_id":51755863638322,"sku":"79031201","price":30.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5d99444e72a70672d5461fdd3b9b1ec4.jpg?v=1788960680","url":"https:\/\/voomisupply.com\/products\/m-a-ford-79031201-60-degree-6-flute-hss-countersink","provider":"Voomi Supply","version":"1.0","type":"link"}
