With a 7\/8 inch head diameter and an 82-degree included angle, this tool produces the precise conical recess needed for flat-head fasteners to sit flush with or below a workpiece surface. The 1\/2 inch shank diameter provides secure grip in standard drill chucks and milling machine collets. High speed steel construction delivers the hardness and heat resistance required for production drilling and general fabrication work.\u003c\/p\u003e\n\u003cp\u003eThis countersink is suited for use in machine shops, fabrication facilities, and maintenance operations where consistent, accurate countersinking is required. The 82-degree included angle matches the seating angle of standard flat-head machine screws and bolts commonly used in metalworking and sheet metal applications. It is appropriate for use in drill presses, milling machines, and hand-held power drills with a 1\/2 inch chuck capacity.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7\/8 inch head diameter for a wide chamfer footprint on standard and oversized fastener heads\u003c\/li\u003e\n  \u003cli\u003e82-degree included angle matches flat-head fastener seating geometry\u003c\/li\u003e\n  \u003cli\u003e6 flutes for smooth cutting action and reduced chatter\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for durability in metal and composite materials\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch shank diameter fits standard drill chucks and collets\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 1\/2 inch drill chucks, drill presses, and milling machine setups requiring an 82-degree countersink profile.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tool is installed and operated by machinists, fabricators, and maintenance technicians. Secure the shank firmly in the chuck or collet before use and confirm the workpiece is clamped to prevent movement. Run at appropriate spindle speeds for the material being cut — lower speeds are recommended for harder metals to extend tool life. Wear appropriate eye protection during operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 82 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 28631\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51700534444338,"sku":"28631","price":54.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e5d7ef7328e0eb1a5d6a1483baaf7c4b.jpg?v=1788391615","url":"https:\/\/voomisupply.com\/products\/value-collection-28631-countersink-7-8in-82-deg-6-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
