Built from high speed steel, it features a 5\/8 inch head diameter and a 100-degree included angle, making it suitable for creating flat-bottomed chamfers and countersunk fastener seats. The 3\/8 inch straight cylindrical shank provides a secure hold in standard drill chucks and collet holders. Six flutes deliver smooth, chatter-resistant cutting action and help clear chips efficiently during operation. This tool is appropriate for use in manual drill presses, CNC machining centers, and handheld power tools where precision chamfering is required.\u003c\/p\u003e\n\u003cp\u003eThe HERTEL 18534 countersink is used across general metalworking, fabrication, and maintenance applications. It is well suited for countersinking screw and bolt holes in steel, aluminum, and similar materials prior to fastener installation. The 100-degree angle accommodates a range of flat-head fastener standards. Machinists, tool-and-die technicians, and maintenance professionals working in production or job-shop environments will find this tool appropriate for both light production runs and one-off tasks.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/8 inch head diameter for countersinking standard fastener hole sizes\u003c\/li\u003e\n  \u003cli\u003e100-degree included angle suits a wide range of flat-head fastener seat profiles\u003c\/li\u003e\n  \u003cli\u003e6 flutes provide smooth cutting action and efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction offers good hardness and wear resistance for general-purpose cutting\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch straight cylindrical shank fits standard drill chucks and collet holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose countersink for use in standard drill chucks and collet-style toolholders accepting a 3\/8 inch straight cylindrical shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or maintenance technicians using a drill press, milling machine, or handheld power drill. Secure the shank firmly in the chuck or collet before use and confirm the workpiece is clamped or fixtured to prevent movement. Apply appropriate cutting fluid for ferrous materials to extend tool life and improve surface finish. Inspect the cutting edges before use and replace the tool if chipping or excessive wear is observed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 5\/8 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 Diameter\u003c\/strong\u003e: 3\/8 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: 18534\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51727870558514,"sku":"18534","price":80.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8afe920f8d05a4e7ec2437b877364973.jpg?v=1788683762","url":"https:\/\/voomisupply.com\/products\/hertel-18534-countersink-5-8-in-100-deg-6-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
