Built from cobalt steel with a bright, uncoated finish, this tool delivers durability and heat resistance in demanding cutting environments. It features a 1-inch counterbore diameter and a 3\/4-inch straight shank, with an overall length of 6-3\/8 inches. The interchangeable pilot design accepts a 5\/16-inch pilot shank, allowing the cutting tool to be paired with different pilot sizes without replacing the entire body. Right-hand cutting geometry is standard. This counterbore is suited for machinists and tool-and-die professionals working with steel and similar materials.\u003c\/p\u003e\n\u003cp\u003eThis counterbore is intended for use in machine shops, maintenance and repair operations, and production environments where accurate counterbored holes are required for socket head cap screws and similar fasteners. The cobalt construction makes it appropriate for harder workpiece materials where high-speed steel tooling may wear prematurely. It fits standard milling machines, drill presses, and CNC machining centers equipped with a compatible 3\/4-inch straight shank holder. The 4-5\/8-inch shank length provides adequate reach for most standard setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-inch counterbore diameter for precise seat creation\u003c\/li\u003e\n  \u003cli\u003eCobalt steel construction for extended tool life in hard materials\u003c\/li\u003e\n  \u003cli\u003e3 flutes for efficient chip evacuation and smooth cutting action\u003c\/li\u003e\n  \u003cli\u003eInterchangeable pilot accepts 5\/16-inch pilot shank diameter\u003c\/li\u003e\n  \u003cli\u003e3\/4-inch straight shank with 4-5\/8-inch shank length for secure tool holding\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish; right-hand cutting direction\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 3\/4-inch straight shank tool holders on drill presses, milling machines, and CNC machining centers; accepts a 5\/16-inch interchangeable pilot shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by qualified machinists or tool operators. Ensure the machine spindle and tool holder are fully powered down and locked out before mounting or changing the tool. Secure the straight shank firmly in a properly sized collet or drill chuck to prevent runout. Always verify pilot shank fit before beginning the cut, and use appropriate cutting fluid for the workpiece material to reduce heat buildup.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCounterbore Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 4-5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6-3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePilot Shank Diameter Compatibility\u003c\/strong\u003e: 5\/16 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAircraft Style\u003c\/strong\u003e: No\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: GH8815649\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51709174317362,"sku":"GH8815649","price":195.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1e018d5ca2d46d511199fd3c9dbba716.jpg?v=1788452360","url":"https:\/\/voomisupply.com\/products\/value-collection-gh8815649-counterbore-1-in-3-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
