Built from high speed steel, it delivers consistent cutting performance across repeated use in production and maintenance environments. The 82-degree included angle matches the standard seating geometry for flat-head fasteners commonly used in aerospace, metalworking, and general fabrication. With six flutes, the tool distributes cutting load evenly, reduces chatter, and produces a smooth finish on the countersunk surface. The 3\/4-inch head diameter and 3\/4-inch straight cylindrical shank allow straightforward mounting in standard drill presses, CNC machining centers, or hand-held power tools with compatible chuck capacity.\u003c\/p\u003e\n\u003cp\u003eThis countersink is suited for use in machine shops, fabrication facilities, and maintenance operations where flat-head fastener seating is required. The 82-degree angle makes it particularly appropriate for aerospace-standard and general-purpose applications where that included angle is specified. Machinists, tool-and-die technicians, and maintenance mechanics typically use this type of tool on steel, aluminum, and other ferrous and non-ferrous workpieces. It is sold individually and is compatible with standard straight-shank toolholders and drill press chucks sized to accept a 3\/4-inch shank.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e82-degree included angle matches flat-head fastener seating standards for general and aerospace applications\u003c\/li\u003e\n  \u003cli\u003eSix flutes distribute cutting forces evenly, minimizing chatter and improving surface finish\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction provides durability and heat resistance for metal cutting\u003c\/li\u003e\n  \u003cli\u003e3\/4-inch straight cylindrical shank fits standard drill press chucks and toolholders\u003c\/li\u003e\n  \u003cli\u003e3\/4-inch head diameter provides adequate coverage for common flat-head fastener sizes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard straight-shank toolholders and drill press chucks that accept a 3\/4-inch diameter shank.

Secure the straight cylindrical shank firmly in a properly sized chuck or toolholder before operation, and verify that the workpiece is clamped or fixtured to prevent movement. Always power down and de-energize the machine before changing or inspecting tooling. Use appropriate cutting fluid or lubricant for the workpiece material to extend tool life and improve cut quality.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/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\u003eIncluded Angle\u003c\/strong\u003e: 82 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\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: 18324\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51744638730546,"sku":"18324","price":223.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fccfb9c461816456ccea02a43872a752.jpg?v=1788859319","url":"https:\/\/voomisupply.com\/products\/hertel-18324-countersink-3-4-in-82-deg-6-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
