Built from high-speed steel with a bright uncoated finish, it cuts a 60-degree included angle with three flutes in a right-hand direction. The 1\/4-inch head diameter and 3\/16-inch straight cylindrical shank make it compatible with standard drill chucks and collet holders. This tool is suited for machinists, tool-and-die workers, and general metalworking shops that need consistent, clean countersunk holes for flat-head fastener seating.\u003c\/p\u003e\n\u003cp\u003eThis countersink is used in drill press, CNC, and hand-drill applications where a 60-degree countersink profile is required. The 3-flute geometry provides a balance between chip clearance and surface finish quality. It does not include a pilot, making it versatile for use across varying hole diameters within its head size range. Typical applications include deburring, chamfering, and fastener-seat preparation in steel, aluminum, and similar metals.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e60-degree included angle for standard countersink fastener profiles\u003c\/li\u003e\n  \u003cli\u003eThree-flute design for balanced chip evacuation and smooth finish\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction for durability in general metalworking\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for dry or lightly lubricated cutting\u003c\/li\u003e\n  \u003cli\u003e3\/16-inch straight cylindrical shank fits standard chucks and collets\u003c\/li\u003e\n  \u003cli\u003eNo pilot required, allowing use across a range of hole diameters\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style single-end countersink for use in standard drill press, CNC, or hand-drill setups requiring a 60-degree countersink profile with a 3\/16-inch straight cylindrical shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tool is installed and operated by machinists or skilled tradespeople familiar with rotating cutting tools. Secure the shank firmly in the chuck or collet before operation and confirm the workpiece is clamped to prevent movement. Use appropriate cutting fluid or lubricant for the workpiece material to extend tool life. Follow standard shop safety practices including eye protection and proper spindle speed selection for the material being cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 1\/4 inch\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\/16 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePilot Included\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\u003eWeight\u003c\/strong\u003e: 0.06 pounds\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: SC4060016\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51709123920178,"sku":"SC4060016","price":20.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8a4049094d5f00aa4bdd9f485c9a6604.jpg?v=1788451629","url":"https:\/\/voomisupply.com\/products\/value-collection-sc4060016-countersink-60-deg-3-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
