Built from high-speed steel (HSS) with a bright\/uncoated finish, it features a 90-degree included angle and a 45-degree centerline angle. The 7\/8-inch head diameter and 1\/2-inch straight-cylindrical shank pair with a 3-inch overall length, making this tool compatible with standard drill presses, milling machines, and handheld power tools. It ships without a pilot. Machinists, tool-and-die workers, and general metalworking trades rely on this countersink for clean, consistent seat angles on fastener holes.\u003c\/p\u003e\u003cp\u003eThis countersink is suited for light to medium machining environments, including job shops, maintenance facilities, and production floors. It is engineered for use on aluminum, brass, magnesium, magnesium alloy, high-nickel steel, Monel, and plastic workpieces. The right-hand cutting direction is standard for conventional machine spindle rotation. The bright\/uncoated finish makes it a cost-effective choice when cutting softer, non-ferrous materials where a specialized coating provides limited additional benefit.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e90-degree included angle with 45-degree centerline angle for standard fastener seat geometry\u003c\/li\u003e\n\u003cli\u003eThree flutes for balanced cutting action and chip clearance\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction provides adequate hardness for non-ferrous metals and plastics\u003c\/li\u003e\n\u003cli\u003e1\/2-inch straight-cylindrical shank fits common drill chucks and collet holders\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish suited for aluminum, brass, Monel, and plastic applications\u003c\/li\u003e\n\u003cli\u003eSingle-end design with no pilot — used where hole pre-alignment is handled separately\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for chamfering and countersinking operations on aluminum, brass, high-nickel steel, magnesium, magnesium alloy, Monel, and plastic.

Secure the 1\/2-inch shank firmly in the chuck or collet before operation and verify runout before cutting. Always power down the machine and lock out the spindle before changing or inspecting the tool. Feed rate and spindle speed should be set according to the workpiece material and machine manufacturer guidelines — consult published speeds-and-feeds charts for HSS tooling on the specific material being machined.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 7\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenterline Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\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: 1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip\/Nose Diameter\u003c\/strong\u003e: 0.2600 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\u003eMaterial Application\u003c\/strong\u003e: Aluminum, Brass, High-Nickel Steel, Magnesium, Magnesium Alloy, Monel, Plastic\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: 92087503\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"M.A. FORD","offers":[{"title":"Default Title","offer_id":51735723802930,"sku":"92087503","price":87.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/973eeffcf56ee255e83e7e5454b275b2.jpg?v=1788773791","url":"https:\/\/voomisupply.com\/products\/m-a-ford-92087503-countersink-90-degree-3-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
