Built from high speed steel, it delivers consistent cutting performance across repeated use in production and maintenance environments. The 100-degree included angle suits a wide range of flat-head fastener applications. The 1\/2-inch head diameter and straight-cylindrical shank make it compatible with standard drill chucks and collet holders. This tool is typically installed and operated by machinists, tool and die technicians, and maintenance professionals working with manual or CNC-assisted drill presses and lathes.\u003c\/p\u003e\u003cp\u003eThis countersink is suited for light to medium-duty deburring, chamfering, and seat preparation in ferrous and non-ferrous metals. The 100-degree angle is a common specification for aerospace and general-purpose flat-head machine screw applications. The straight-cylindrical shank fits standard 1\/2-inch drill chucks without adapters, making it a practical choice for shop floor and field maintenance use where quick setup is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e6 flutes for smooth, chatter-resistant cutting and improved finish quality\u003c\/li\u003e\n\u003cli\u003e100-degree included angle sized for common flat-head fastener seat preparation\u003c\/li\u003e\n\u003cli\u003e1\/2-inch head diameter with matching 1\/2-inch straight-cylindrical shank\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction for durability across repeated cutting cycles\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose countersink for use in standard 1\/2-inch drill chucks, collet holders, and compatible machine spindles accepting straight-cylindrical shanks.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCountersinks are installed and operated by machinists and maintenance technicians using drill presses, lathes, or hand drills. Secure the shank firmly in the chuck before use and confirm the workpiece is properly clamped. Run at appropriate spindle speeds for the material being cut — lower speeds are generally preferred for steel to extend tool life. Inspect the cutting edges before each use and do not force a dull tool.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 100 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 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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 18316\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51731877396786,"sku":"18316","price":111.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1b725c5b9b7782c3acc5a598f450a03e.jpg?v=1788735964","url":"https:\/\/voomisupply.com\/products\/hertel-18316-countersink-1-2-in-100-degree-6-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
