Built from high speed steel, it delivers consistent cutting performance on a range of workpiece materials. The 1-1\/4 inch head diameter and 60-degree included angle make it suited for creating clean, accurate countersunk seats for flathead fasteners or chamfered edge profiles. The 1\/2 inch straight-cylindrical shank provides secure chuck engagement in standard drill presses, milling machines, and hand drills. Machinists and tool and die professionals are the primary installers and users of this tool.\u003c\/p\u003e\n\u003cp\u003eThis countersink is used in shop and field settings where a precise 60-degree chamfer is required. Typical applications include countersinking pilot holes for flathead machine screws, deburring drilled holes in steel, aluminum, and similar materials, and producing clean chamfered entries on through-holes. Its single-flute geometry reduces chatter during operation, which is especially useful when working with softer metals or when surface finish quality is a priority on the chamfered face.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-1\/4 inch head diameter for wide chamfer coverage\u003c\/li\u003e\n  \u003cli\u003e60-degree included angle for standard flathead fastener seating\u003c\/li\u003e\n  \u003cli\u003eSingle-flute design minimizes chatter and improves surface finish\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction provides durability across common metalworking materials\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch straight-cylindrical shank fits standard drill chuck and collet setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a straight-shank countersink compatible with drill presses, milling machine spindles, and hand drills accepting a 1\/2 inch straight-cylindrical shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tool is installed and operated by machinists and metalworking trades. Secure the shank fully in the chuck or collet before operation and verify runout is within acceptable limits for the application. Use appropriate cutting fluid for the workpiece material to extend tool life and improve finish quality. Always wear appropriate eye protection and secure the workpiece before engaging the spindle.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 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: 0.5 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: 18041\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51749173100850,"sku":"18041","price":190.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f98c6317d63e45796f01ba6e068692ac.jpg?v=1788902910","url":"https:\/\/voomisupply.com\/products\/hertel-18041-countersink-1-1-4-in-60-degree-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
