Countersinks of this type are used to create the angled seat at the mouth of a drilled hole, allowing flat-head fasteners to sit flush with or below the workpiece surface. The 82-degree angle is the standard for inch-series flat-head screws. The HSS construction handles a wide range of materials, including mild steel, aluminum, brass, and plastic. At 0.75 pounds, this is a solid, hand-held or machine-mounted tool suited for production and maintenance work.\u003c\/p\u003e\n\u003cp\u003eThis countersink is appropriate for metalworking, fabrication, and general machining applications where a clean, consistent countersink profile is required. The 4-flute design provides a smooth finish and improved chatter resistance compared to single-flute designs, making it well suited for drill press, milling machine, or hand-drill use. Typical users include machinists, pipefitters, millwrights, and maintenance technicians working with fastener-mounted assemblies in industrial or commercial settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7\/8-inch cutting diameter for standard fastener seat preparation\u003c\/li\u003e\n  \u003cli\u003e82-degree included angle matches inch-series flat-head screw standards\u003c\/li\u003e\n  \u003cli\u003e4-flute geometry reduces chatter and improves surface finish\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction compatible with mild steel, aluminum, brass, and plastics\u003c\/li\u003e\n  \u003cli\u003eImport-grade tooling suitable for general-purpose and production use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose countersink for use with standard inch-series 82-degree flat-head screws and machine screws.

Always secure the workpiece firmly before beginning a countersink operation, and set spindle speed appropriate for the workpiece material and tool diameter. Use cutting fluid when countersinking ferrous metals to extend tool life and improve finish quality. Inspect the cutting edges before use and do not operate with a chipped or worn flute.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 7\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 82 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel (HSS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.75 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 1\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: EAGLE CUTTING TOOL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: MCS-8750-82-4-I\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EAGLE CUTTING TOOL","offers":[{"title":"Default Title","offer_id":51233705820466,"sku":"MCS-8750-82-4-I","price":42.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307623316.png?v=1780107221","url":"https:\/\/voomisupply.com\/products\/eagle-cutting-tool-mcs-8750-82-4-i-7-8-in-82-deg-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
