It features a 5\/16-inch head diameter and an 82-degree included angle, making it suitable for standard flat-head fastener seating in a variety of workpiece materials. The 1\/4-inch shank diameter provides compatibility with common drill chucks and quick-change holders. Constructed from high speed steel (HSS), this countersink offers adequate hardness and wear resistance for general-purpose countersinking tasks. It is a straightforward, single-flute design used by machinists, fabricators, and maintenance technicians across light manufacturing and trade shop environments.\u003c\/p\u003e\n\u003cp\u003eThis countersink is used in applications where a 82-degree countersink angle is required for standard flat-head machine screws and fasteners. It is appropriate for use in hand drills, drill presses, and milling machines. Typical applications include deburring drilled holes, preparing bolt and screw seating surfaces, and light countersinking in sheet metal and structural components. It is sold individually and suited for both shop and field use where a compact, general-purpose countersink is needed.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-inch head diameter sized for standard flat-head fastener countersinks\u003c\/li\u003e\n  \u003cli\u003e82-degree included angle for compatibility with common flat-head screw specifications\u003c\/li\u003e\n  \u003cli\u003eSingle-flute design for straightforward countersinking operation\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch shank diameter fits standard drill chucks and quick-change systems\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction provides hardness for general-purpose 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 1\/4-inch shank drill chucks and quick-change holders in hand drills, drill presses, and milling machines.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSecure the 1\/4-inch shank firmly in the drill chuck or quick-change holder before operation. Use appropriate speed settings for the workpiece material — lower RPM for harder metals, higher RPM for softer materials and wood. Always wear appropriate eye protection and secure the workpiece before beginning. Inspect the cutting edge for wear or damage before each use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 5\/16 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: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/4 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\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 28602\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51698114724146,"sku":"28602","price":20.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/84288e6dcd9abf68aaec437c29784daa.jpg?v=1788357919","url":"https:\/\/voomisupply.com\/products\/value-collection-28602-countersink-5-16-in-hss-1-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
