With a 2-inch head diameter and 6 flutes, this tool delivers smooth cutting action and reduced chatter compared to single- or three-flute designs. The straight-cylindrical shank measures 1 inch in diameter and 2.125 inches in length, making it compatible with standard drill press chucks and milling machine collets. It is built for machinists, tool and die technicians, and metalworking professionals who require consistent, repeatable countersink geometry in production or maintenance environments.\u003c\/p\u003e\u003cp\u003eThis countersink is suited for deburring, chamfering, and seat preparation on drilled holes in ferrous and non-ferrous metals. The 6-flute configuration distributes cutting load evenly, which is particularly useful when working with harder steels or when surface finish quality is critical. It is commonly used in machine shops, fabrication facilities, and maintenance departments where precision fastener seat preparation is a routine operation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e2-inch head diameter for large-diameter countersink applications\u003c\/li\u003e\n\u003cli\u003e90-degree included angle — standard for flat-head fastener seating\u003c\/li\u003e\n\u003cli\u003e6 flutes for smooth cutting and reduced chatter\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction for durability across ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003e1-inch straight-cylindrical shank fits standard drill press and milling machine toolholders\u003c\/li\u003e\n\u003cli\u003eShank length of 2.125 inches provides adequate grip depth in most chucks and collets\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard drill press chucks, milling machine collets, and toolholders accepting a 1-inch straight-cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tool is installed by machinists and metalworking technicians using standard chuck or collet toolholding equipment. Ensure the machine spindle is fully stopped and locked out before mounting or removing the countersink. Secure the shank to the full recommended grip depth in the chuck or collet to prevent slippage under load. Use appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 90 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 Diameter\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\u003eShank Length\u003c\/strong\u003e: 2.125 inches\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: 18126\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51744477675826,"sku":"18126","price":581.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6cfe4cdab51b3fbdbbca0db847d2c8a3.jpg?v=1788857099","url":"https:\/\/voomisupply.com\/products\/hertel-18126-countersink-2-in-90-degree-6-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
