Built from high speed steel, this tool delivers consistent cutting performance across a range of materials. It features a 29\/32-inch counterbore diameter, a 1\/4-inch straight shank, and four flutes configured for right-hand cutting. The 3.125-inch overall length suits standard machining setups. The bright, uncoated and polished finish allows operators to visually inspect cutting edge condition at a glance. Machinists and maintenance technicians working in aircraft-style applications will find this tool sized and configured to meet those specific workflow requirements.\u003c\/p\u003e\u003cp\u003eThis counterbore is suited for use in machine shop, aerospace, and general metalworking environments where a counterbore of 29\/32-inch diameter is required. The interchangeable pilot design supports flexible setups by allowing pilot replacement without replacing the full tool body. A 3\/16-inch pilot shank diameter compatibility makes it appropriate for applications where that pilot size is standard. The aircraft-style designation indicates compliance with tooling configurations common in aerospace fabrication and MRO work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e29\/32-inch counterbore diameter for precise seat cutting\u003c\/li\u003e\n\u003cli\u003e1\/4-inch straight shank for compatibility with standard tool holders\u003c\/li\u003e\n\u003cli\u003eFour flutes for efficient chip evacuation during right-hand cutting\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction for durability across common workpiece materials\u003c\/li\u003e\n\u003cli\u003eInterchangeable pilot design allows pilot swaps without replacing the counterbore body\u003c\/li\u003e\n\u003cli\u003eBright, polished finish for easy visual inspection of cutting edges\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use tool for applications requiring a 29\/32-inch interchangeable pilot counterbore with a 3\/16-inch pilot shank diameter compatibility and a 1\/4-inch straight shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use of this counterbore should be performed by qualified machinists or tool and die personnel familiar with rotating cutting tools. Secure the straight shank firmly in a drill press, milling machine, or hand-held power tool chuck before operation. Ensure the workpiece is clamped or fixtured to prevent movement during cutting. Always disconnect power or lock out the machine before changing pilots or inspecting the cutting edges.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCounterbore Diameter\u003c\/strong\u003e: 29\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\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: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.125 inches\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: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright, Uncoated, Polished\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAircraft Style\u003c\/strong\u003e: Yes\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: GH8840589\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51699269665074,"sku":"GH8840589","price":141.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7bc4f2da254115c5a1a0383c7eead50f.jpg?v=1788374383","url":"https:\/\/voomisupply.com\/products\/value-collection-gh8840589-counterbore-29-32-in-4-fl-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
