Built from high-speed steel (HSS) with a bright\/uncoated finish, it features a 60-degree included angle and a 5\/8-inch head diameter. The straight-cylindrical shank measures 3\/8 inch in diameter with a 1-inch shank length, making it compatible with standard drill chucks and countersink holders. This tool is suited for deburring holes and creating chamfered seat profiles for flat-head fasteners in production and maintenance environments. No pilot is included.\u003c\/p\u003e\n\u003cp\u003eThis countersink is used in metal shop, manufacturing, and maintenance-repair-operations (MRO) settings where precise chamfer angles are required before fastener seating. It is appropriate for use in steel, aluminum, and similar workpiece materials typical of light-to-medium machining work. The 60-degree included angle matches standard flat-head machine screw seat geometry commonly encountered in precision assemblies. Machinists, tool-and-die technicians, and maintenance mechanics are the typical end users for this style of countersink.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e60-degree included angle for standard flat-head fastener seating\u003c\/li\u003e\n  \u003cli\u003e3 flutes for improved chip evacuation and surface finish\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction for durability across common workpiece materials\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish — suitable for general-purpose countersinking\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical 3\/8-inch shank fits standard drill chucks and holders\u003c\/li\u003e\n  \u003cli\u003eSingle-end design with no pilot — maximizes flexibility across hole sizes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose countersink for use in standard drill presses, milling machines, and hand-drill applications that accept a 3\/8-inch straight-cylindrical shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eCountersinks are installed and operated by machinists and maintenance technicians using standard drill chucks or dedicated countersink holders. Secure the workpiece fully before operation to prevent rotation or movement. Run at appropriate spindle speeds for the workpiece material — higher speeds for aluminum, reduced speeds for steel — following the tool manufacturer's general speed-and-feed guidelines. Inspect the cutting edges for wear before each use and replace when the chamfer finish degrades.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 5\/8 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: 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: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1 inch\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\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Countersinking\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.11 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: SC4060040\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51720474984754,"sku":"SC4060040","price":27.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c07b6e042a0b8fdb81c950d4428a7f56.jpg?v=1788564601","url":"https:\/\/voomisupply.com\/products\/value-collection-sc4060040-countersink-60-degree-3-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
