Manufactured from high speed steel (HSS) with a bright polished finish, these counterbores deliver clean, precise seating recesses in metal workpieces. Each tool features a standard Morse taper shank for secure mounting in compatible drilling equipment and a 3-flute cutting geometry that promotes chip evacuation and dimensional accuracy. This set is used by machinists, tool and die makers, and maintenance technicians working on machine assemblies and structural fastening applications.\u003c\/p\u003e\n\u003cp\u003eThis counterbore set covers the common socket-head cap screw size range from 1\/4 inch through 1\/2 inch, making it well suited for general machining, fixture building, and machine maintenance in job shop or industrial environments. The solid pilot design provides positive tool guidance during cutting, reducing walk and improving hole concentricity. The Morse taper shank allows use in drill presses and milling machines equipped with a compatible taper socket or adapter.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHigh speed steel construction for hardness and wear resistance in metal cutting applications\u003c\/li\u003e\n  \u003cli\u003eBright polished finish reduces friction and aids chip flow during cutting\u003c\/li\u003e\n  \u003cli\u003e3-flute cutting geometry promotes chip evacuation and smooth bore finish\u003c\/li\u003e\n  \u003cli\u003eStandard solid pilot design guides the tool and maintains concentricity with the pilot hole\u003c\/li\u003e\n  \u003cli\u003eMorse taper shank mounts securely in drill presses and milling machines with compatible taper receivers\u003c\/li\u003e\n  \u003cli\u003e4-piece set covers socket-head cap screw sizes from 1\/4 inch to 1\/2 inch\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with socket-head cap screws in the 1\/4 inch to 1\/2 inch size range.

Secure the Morse taper shank fully in the spindle before operation and verify the pilot diameter matches the existing pilot hole in the workpiece. Power down and lock out the machine before changing tools or inspecting cutting edges. Do not exceed the recommended speed range for the workpiece material and tool diameter.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright (Polished)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePilot Type\u003c\/strong\u003e: Standard Solid Pilot\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Morse Taper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Screw Size Range\u003c\/strong\u003e: 1\/4 inch to 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePieces Included\u003c\/strong\u003e: 4\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: 381-9044\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51699194233138,"sku":"381-9044","price":385.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0860d45ae057c0a2038c3c577e7fa392.jpg?v=1788373352","url":"https:\/\/voomisupply.com\/products\/value-collection-381-9044-counterbore-set-hss-4-piece","provider":"Voomi Supply","version":"1.0","type":"link"}
