Built from cobalt steel with a bright, uncoated finish, this counterbore delivers strong cutting performance in ferrous and hard materials. It features a 3\/4-inch counterbore diameter and a 21\/32-inch pilot diameter, with a 31\/32-inch straight-cylindrical shank for secure chuck or holder engagement. Forward cutting direction makes it suitable for standard drilling setups. Machinists and toolroom technicians typically specify this tool for production and maintenance drilling operations.\u003c\/p\u003e\n\u003cp\u003eThis counterbore is used in metalworking applications where a precise, flat-bottomed recess is required above a through or blind hole. Common scenarios include socket head cap screw seating, dowel pin spotting, and similar precision machining tasks on mill or drill press setups. The solid pilot design provides accurate hole alignment during cutting, reducing chatter and improving finish quality in both manual and CNC machining environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt steel construction for improved heat and wear resistance compared to standard HSS\u003c\/li\u003e\n  \u003cli\u003e3\/4-inch counterbore diameter for accurate fastener-head recessing\u003c\/li\u003e\n  \u003cli\u003e21\/32-inch solid pilot diameter for positive hole alignment during cutting\u003c\/li\u003e\n  \u003cli\u003e31\/32-inch straight-cylindrical shank for reliable chuck or collet holding\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suitable for use with cutting fluids across a range of materials\u003c\/li\u003e\n  \u003cli\u003eForward cutting direction compatible with standard drill press and milling machine setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a solid pilot counterbore for use in standard drill press, milling machine, or CNC drilling applications requiring a 3\/4-inch counterbore and 21\/32-inch pilot.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and operation should be performed by qualified machinists or toolroom personnel. Secure the 31\/32-inch straight shank firmly in an appropriate chuck or collet before operation, and ensure the machine is fully powered down and locked out before changing or adjusting tooling. Use an appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Follow applicable shop safety standards and machine manufacturer guidelines during all cutting operations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCounterbore Diameter\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePilot Diameter\u003c\/strong\u003e: 21\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 31\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Forward\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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: 0.95 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241603\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: CD60040\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51690569498930,"sku":"CD60040","price":136.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1ad44e53630d9b8b223e0471354038c5.jpg?v=1788271865","url":"https:\/\/voomisupply.com\/products\/value-collection-cd60040-solid-pilot-counterbore-3-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
