With a 1\/2 inch head diameter and an 82 degree included angle, this tool produces flat-head fastener seats that meet standard aerospace and industrial fastener specifications. The 3\/8 inch straight-cylindrical shank fits standard drill chucks and collet holders, making it compatible with most benchtop drill presses and CNC machining centers. A bright, uncoated finish keeps the carbide substrate exposed for maximum hardness and cutting efficiency. Machinists, tool-and-die technicians, and general fabricators rely on this style of countersink for production and maintenance work where seat geometry must be consistent.\u003c\/p\u003e\n\u003cp\u003eThis countersink is suited for light to medium production environments where 82 degree flat-head screws and fasteners are standard. The 3-flute geometry balances cutting speed with surface finish quality, making it appropriate for both manual drill press operations and CNC-assisted hole finishing. Common applications include deburring pre-drilled holes, preparing fastener seats in sheet metal assemblies, and countersinking structural panels. The single-end, no-pilot design gives the operator direct control over hole centering, which is appropriate when working with pre-spotted or pre-drilled locations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2 inch head diameter with 82 degree included angle for standard flat-head fastener compatibility\u003c\/li\u003e\n  \u003cli\u003e3-flute carbide construction for consistent chip evacuation and seat finish quality\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch straight-cylindrical shank fits standard chucks and collet tool holders\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction for use with conventional clockwise spindle rotation\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish preserves carbide hardness without coating interference\u003c\/li\u003e\n  \u003cli\u003eSingle-end, no-pilot design for use in pre-drilled or pre-spotted hole locations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard countersink for use with 82 degree flat-head fastener applications in metalworking, fabrication, and machining operations where a 3\/8 inch shank toolholder or drill chuck is available.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by a qualified machinist or trained shop technician familiar with proper speeds and feeds for carbide tooling. Secure the shank fully in the chuck or collet before operation and confirm the spindle is stopped completely before making any tool adjustments or workpiece changes. Use appropriate cutting fluid or coolant for the workpiece material to extend tool life and improve surface finish. Do not exceed the recommended RPM range for the workpiece material and tool diameter.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 82 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenterline Angle\u003c\/strong\u003e: 41 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncludes Pilot\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Countersinking\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.07 pounds\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: 333-006560\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51730484625714,"sku":"333-006560","price":65.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9fcc8633987ae2702fa0f134d0ee0225.jpg?v=1788718285","url":"https:\/\/voomisupply.com\/products\/hertel-333-006560-countersink-1-2-in-82-deg-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
