Built from cobalt steel for heat and wear resistance, this tool features a 6 mm cutting diameter, a 3.4 mm pilot diameter, and three flutes for clean, efficient material removal. The straight-cylindrical shank measures 0.219 inches in diameter, providing consistent tool holding in standard drill press and milling machine chucks. With an overall length of approximately 2.99 inches (76 mm), it handles typical countersinking tasks in production and job-shop environments. Machinists, toolmakers, and maintenance technicians use this tool when fastener seat accuracy is required.\u003c\/p\u003e\n\u003cp\u003eThis counterbore is suited for forward-cutting operations in ferrous and other hard materials where cobalt steel provides an advantage over standard high-speed steel tooling. It is sized for use with 3 mm fasteners, making it appropriate for light machine assembly, fixture work, and precision part fabrication in both manual and CNC-assisted setups. The three-flute geometry balances chip evacuation with surface finish quality, reducing chatter at the cutting seat.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e6 mm counterbore diameter sized for 3 mm fastener compatibility\u003c\/li\u003e\n  \u003cli\u003e3.4 mm pilot diameter for accurate seat alignment during cutting\u003c\/li\u003e\n  \u003cli\u003eThree-flute design improves chip evacuation and reduces chatter\u003c\/li\u003e\n  \u003cli\u003eCobalt steel construction resists heat buildup in hard-material applications\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank at 0.219 inches fits standard toolholders\u003c\/li\u003e\n  \u003cli\u003eForward cutting direction compatible with conventional drill press and milling setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard solid pilot counterbore for use with 3 mm fasteners in metalworking, machining, and fabrication applications requiring a piloted cutting seat.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by qualified machinists or toolroom technicians familiar with rotating cutting tool safety. Secure the straight shank firmly in a compatible toolholder or chuck before operation and confirm runout is within acceptable limits. Power down the machine and release all stored energy before changing or inspecting the tool. Always use appropriate cutting fluid for the workpiece material to extend tool life and maintain cutting geometry.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCounterbore Diameter\u003c\/strong\u003e: 6 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePilot Diameter\u003c\/strong\u003e: 3.4 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Size Compatibility\u003c\/strong\u003e: 3 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.219 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 76 mm (approximately 2.99 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Forward\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.035 pounds\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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: E1419003\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51714394915122,"sku":"E1419003","price":37.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/367dc7ee8ae20ed1025a72fe55ece2cb.jpg?v=1788500871","url":"https:\/\/voomisupply.com\/products\/value-collection-e1419003-solid-pilot-counterbore-6mm","provider":"Voomi Supply","version":"1.0","type":"link"}
