With a 5\/16-inch head diameter and an 82-degree included angle, this tool produces the precise conical profile required for flat-head screws and similar hardware. The straight cylindrical shank measures 1\/4 inch in diameter, making it compatible with standard drill chucks and quick-change holders. Constructed from high speed steel, it delivers the hardness and wear resistance needed for repetitive use in production or maintenance environments. Machinists, tool and die technicians, and maintenance professionals use this countersink for light to medium-duty applications.\u003c\/p\u003e\n\u003cp\u003eThis countersink is suited for use in machine shops, fabrication facilities, and maintenance operations where consistent countersink geometry is required. The 82-degree included angle matches the seating angle of standard flat-head fasteners used widely in North American manufacturing and assembly. The single-flute design allows for clean cutting in softer metals and reduces chatter during the countersinking operation. It is typically run in a drill press, milling machine, or handheld drill at speeds appropriate for the workpiece material.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-inch head diameter for compact countersink profiles\u003c\/li\u003e\n  \u003cli\u003e82-degree included angle matches standard flat-head fastener seating geometry\u003c\/li\u003e\n  \u003cli\u003eSingle-flute design minimizes chatter and promotes clean cutting\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch straight cylindrical shank fits standard drill chucks and quick-change holders\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction provides hardness and wear resistance for repetitive use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use countersink for applications requiring an 82-degree included angle and a 1\/4-inch straight cylindrical shank in standard drill chucks and compatible toolholders.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tool is installed by machinists or maintenance technicians using a drill press, milling machine, or handheld power drill. Secure the 1\/4-inch shank firmly in the chuck before operation and verify the workpiece is clamped or fixtured to prevent movement. Select an appropriate cutting speed for the workpiece material to avoid overheating the high speed steel cutting edge. Do not force the tool or use it at angles outside its intended application.\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\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel\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: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 19202\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51733106524466,"sku":"19202","price":43.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/73250d55d945413d1d2e705c9f6ac6ad.jpg?v=1788751438","url":"https:\/\/voomisupply.com\/products\/hertel-19202-countersink-5-16-in-82-degree-1-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
