Built from cobalt steel with a bright, uncoated finish, this tool delivers durability and heat resistance suited for drilling harder materials. The straight shank measures 1\/2 inch in diameter and 3-7\/8 inches in length, while the counterbore head diameter is 19\/32 inch. Overall length is 5-1\/8 inches. Right-hand cutting direction is standard. This counterbore is sized and constructed for use by machinists, tool-and-die shops, and maintenance technicians who require consistent, repeatable counterbored holes.\u003c\/p\u003e\u003cp\u003eThis counterbore is well suited for drilling counterbored recesses in ferrous and non-ferrous metals in both production shop and job-site maintenance environments. The interchangeable pilot design allows the pilot to be swapped to match different fastener clearance requirements, making it a flexible option for shops working with varied bolt and screw sizes. Compatible with standard drill presses, milling machines, and CNC machining centers that accept 1\/2-inch straight shank tooling. The 19\/32-inch counterbore diameter accommodates common fastener head recess sizes used in structural and mechanical assembly work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e19\/32 inch counterbore diameter for precision fastener head recessing\u003c\/li\u003e\n\u003cli\u003eCobalt steel construction for improved heat and wear resistance in harder materials\u003c\/li\u003e\n\u003cli\u003e3-flute geometry provides smooth cutting action and efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eInterchangeable pilot accepts 3\/16 inch pilot shank for flexible fastener compatibility\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish for easy visual inspection of cutting edge condition\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction compatible with standard drill press and milling machine spindles\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in drill presses, milling machines, and CNC machining centers equipped with 1\/2-inch straight shank tool holders.

Secure the straight shank firmly in an appropriate 1\/2-inch collet or drill chuck before operation, and verify that the pilot is properly seated before engaging the workpiece. Always power down and lock out the machine before changing pilots or inspecting the cutting edges. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain surface finish quality.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCounterbore Diameter\u003c\/strong\u003e: 19\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 3-7\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5-1\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePilot Shank Diameter Compatibility\u003c\/strong\u003e: 3\/16 inches\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\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\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: GH8815383\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51692759580978,"sku":"GH8815383","price":122.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4ff76ca4347ce82319c6fb82ec46138a.jpg?v=1788302425","url":"https:\/\/voomisupply.com\/products\/value-collection-gh8815383-counterbore-19-32-in-3-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
