Built from high-speed steel with a bright, uncoated finish, this tool features a 19\/32-inch counterbore diameter and a 1\/2-inch straight shank. The overall length is 5-1\/8 inches, with a shank length of 3-7\/8 inches. Right-hand cutting geometry keeps the tool stable and consistent during operation. Machinists and tool-and-die professionals rely on this style of counterbore for clean, flat-bottom recesses sized to accept socket-head cap screws and similar fasteners.\u003c\/p\u003e\u003cp\u003eThis counterbore is suited for use in machine shops, maintenance facilities, and production environments where controlled counterbore depth and diameter accuracy are required. Compatible pilot shank diameter is 3\/16 inch, allowing the use of interchangeable pilots to maintain concentricity with a drilled or existing hole. Rated for use in alloy tool steel, aluminum, cast iron, low-carbon steel, and medium-carbon steel.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e19\/32-inch counterbore diameter with a 3-flute right-hand cutting configuration\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction for durability across ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for general-purpose machining applications\u003c\/li\u003e\n\u003cli\u003e1\/2-inch straight shank for compatibility with standard drill press and milling machine chucks\u003c\/li\u003e\n\u003cli\u003eInterchangeable pilot design accepts 3\/16-inch pilot shank diameter for concentricity control\u003c\/li\u003e\n\u003cli\u003e5-1\/8-inch overall length with 3-7\/8-inch shank length for reach in typical setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eAccepts interchangeable pilots with a 3\/16-inch pilot shank diameter.

Secure the straight shank firmly in a properly sized chuck before operation, and verify that the selected pilot is seated and locked before beginning the cut. Always reduce spindle speed when transitioning between materials of differing hardness, and use appropriate cutting fluid for the workpiece material to extend tool life and maintain bore 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 inch (0.5000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\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\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePilot Shank Diameter Compatibility\u003c\/strong\u003e: 3\/16 inch\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\u003eMaterial Application\u003c\/strong\u003e: Alloy Tool Steel, Aluminum, Cast Iron, Low-Carbon Steel, Medium-Carbon Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAircraft Style\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: C46434\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51699558220082,"sku":"C46434","price":288.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6be40e0c6c85ad69271384dcb27827fb.jpg?v=1788377423","url":"https:\/\/voomisupply.com\/products\/cleveland-c46434-counterbore-19-32-in-3-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
