Built from high-speed steel with a bright, uncoated finish, this tool delivers reliable performance in alloy tool steel, carbon steel, and cast iron. It features a 0.242-inch counterbore diameter, a 0.150-inch standard pilot diameter, and three flutes for efficient chip evacuation. The straight-cylindrical shank measures 7\/32 inches in diameter and the overall length is 3 inches. Cutting direction is forward. This tool is suited for machinists, tool-and-die makers, and maintenance technicians working in production or job-shop environments.\u003c\/p\u003e\u003cp\u003eThis counterbore is sized specifically for No. 6 socket-head cap screws, making it a practical choice for general fabrication, fixture building, and mechanical assembly operations where fastener head clearance is required. It performs well in manual drill press setups and CNC machining center applications where a solid-pilot counterbore is preferred over interchangeable-pilot designs. The high-speed steel construction handles moderate cutting speeds across the listed material applications without requiring specialized coolant or coatings for typical shop use.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.242-inch counterbore diameter sized for No. 6 socket-head cap screws\u003c\/li\u003e\n\u003cli\u003e0.150-inch standard pilot diameter for accurate bore alignment\u003c\/li\u003e\n\u003cli\u003eThree-flute geometry promotes chip clearance during cutting\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction for use in alloy tool steel, carbon steel, and cast iron\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical 7\/32-inch shank for compatibility with standard drill chucks and collets\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish — forward cutting direction\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with No. 6 socket-head cap screws.

Secure the straight-cylindrical shank firmly in a drill chuck or collet before operation and verify the pilot is properly seated in the existing pilot hole before engaging the cut. Power down all equipment and lock out energy sources before changing tooling. Do not exceed the recommended cutting speed for the workpiece material to avoid premature tool wear.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCounterbore Diameter\u003c\/strong\u003e: 0.242 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePilot Diameter\u003c\/strong\u003e: 0.150 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePilot Type\u003c\/strong\u003e: Standard\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-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 7\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Forward\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFastener Size Compatibility\u003c\/strong\u003e: No. 6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFastener Type Compatibility\u003c\/strong\u003e: Socket-Head Cap Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Alloy Tool Steel, Carbon Steel, Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: CLEVELAND\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C91696\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51720723104050,"sku":"C91696","price":182.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5b8f8c81a04c23f7f432d365a5010c0e.jpg?v=1788568239","url":"https:\/\/voomisupply.com\/products\/cleveland-c91696-solid-pilot-counterbore-0-242-in-3-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
