It features a 1-inch head diameter and an 82-degree included angle, which corresponds to a 41-degree centerline angle — geometry suited for standard flat-head fastener seating in metal fabrication and machining applications. The 1\/2-inch straight-cylindrical shank fits standard drill chucks and milling machine toolholders. An oxide coating helps reduce friction and provides basic corrosion resistance during cutting. Machinists, tool-and-die workers, and general metal fabricators are the typical users of this tool.\u003c\/p\u003e\n\u003cp\u003eThis countersink is intended for use in machine shop environments and production drilling operations where consistent countersink depth and angle are required. The 82-degree angle matches the head geometry of many metric and imperial flat-head fasteners used in carbon steel and cast iron assemblies. With 3 flutes and no pilot, it is suited for use in drill presses, milling machines, and CNC machining centers where the spindle provides the necessary centering control. It is not designed for wood or composite materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-inch head diameter for large-diameter countersink applications\u003c\/li\u003e\n  \u003cli\u003e82-degree included angle matches standard flat-head fastener geometry\u003c\/li\u003e\n  \u003cli\u003e3-flute design for smooth chip evacuation in ferrous materials\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for durability in carbon steel and cast iron\u003c\/li\u003e\n  \u003cli\u003eOxide coating reduces friction and provides basic surface protection\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch straight-cylindrical shank for compatibility with standard toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for countersinking operations in carbon steel and cast iron.

Secure the shank firmly in the toolholder before operation and verify that workpiece clamping is adequate to prevent movement during cutting. Use appropriate cutting fluid for the material being machined to extend tool life and improve finish quality. Always power down and lock out the machine spindle before changing or inspecting the tool.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 82 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenterline Angle\u003c\/strong\u003e: 41 degrees\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\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch (12.70 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncludes Pilot\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Carbon Steel, Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112812\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: CLEVELAND\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C46181\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51718727008562,"sku":"C46181","price":151.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0bd054a60e8255ddd82a191ee4949ce2.jpg?v=1788555230","url":"https:\/\/voomisupply.com\/products\/cleveland-c46181-countersink-1-in-82-deg-3-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
