With a 3\/8 inch head diameter and an 82-degree included angle, this tool produces clean, consistent countersunk seats for flat-head fasteners. The straight-cylindrical shank measures 3\/8 inch in diameter, making it compatible with standard drill chucks and collet holders. The carbide construction provides superior hardness and wear resistance compared to high-speed steel, extending tool life when working with abrasive or hardened workpiece materials. Machinists, toolroom technicians, and metal fabricators are the primary users of this tool.\u003c\/p\u003e\n\u003cp\u003eThis countersink is suited for use in manual drill presses, CNC machining centers, and hand-held power tools where a 3\/8 inch straight shank can be gripped securely. The 82-degree included angle is the standard angle specified for most imperial flat-head machine screws and is commonly required in aerospace, automotive, and general metalworking applications. The single-flute geometry reduces chatter and produces a smoother finish in the countersunk recess compared to multi-flute designs, making it a practical choice for finish-critical work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCarbide construction for extended wear resistance in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003e82-degree included angle matches standard imperial flat-head fastener geometry\u003c\/li\u003e\n  \u003cli\u003eSingle-flute design minimizes chatter and improves surface finish quality\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch straight-cylindrical shank fits standard drill chucks and collet holders\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch head diameter suitable for common fastener countersink sizes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use countersink for applications requiring an 82-degree, single-flute carbide tool with a 3\/8 inch straight-cylindrical shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tool is installed and operated by machinists or toolroom technicians in machine shop environments. Secure the straight shank firmly in a drill chuck or collet before use and verify runout is within acceptable tolerance to prevent premature tool wear. Always power down and de-energize the machine spindle before installing or removing the tool. Use appropriate cutting fluid or coolant for the workpiece material to maximize tool life and surface finish 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\/8 inches\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: 1\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: Carbide\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: 331-205060\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51728185655602,"sku":"331-205060","price":127.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/56af099f96cda1b78a90364e53f79a95.jpg?v=1788689162","url":"https:\/\/voomisupply.com\/products\/hertel-331-205060-countersink-3-8-in-carbide-1-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
