The tool features a 90-degree included angle and a 0.75-inch head diameter, making it well suited for preparing holes to accept flat-head fasteners flush with or below the surface. Constructed from high speed steel with an oxide finish for reduced friction, the C46224 uses a straight-cylindrical 0.5-inch shank for secure chuck engagement. Licensed tradespeople and machinists working in fabrication, tool-and-die, and general metalworking shops rely on this tool for consistent countersink geometry.\u003c\/p\u003e\n\u003cp\u003eThe C46224 is intended for countersinking operations in alloy tool steel and cast iron. Its right-hand cutting direction and 4-flute configuration help control chip evacuation and minimize chatter during the cut. The straight-cylindrical shank mounts directly in standard drill press or milling machine chucks without an adapter. Typical applications include pre-drilling fastener seats in structural steel assemblies, machine housings, and fixture plates where flat-head cap screws or machine screws must sit flush.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e90-degree included angle for standard flat-head fastener seating\u003c\/li\u003e\n  \u003cli\u003e0.75-inch head diameter with a 45-degree centerline angle\u003c\/li\u003e\n  \u003cli\u003e4-flute design supports controlled chip evacuation and reduced chatter\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for durability in ferrous materials\u003c\/li\u003e\n  \u003cli\u003eOxide finish reduces friction and surface adhesion during cutting\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical 0.5-inch shank fits standard drill press and mill chucks\u003c\/li\u003e\n  \u003cli\u003eSingle-end, no-pilot configuration for versatile hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for countersinking operations in alloy tool steel and cast iron.

Use appropriate cutting fluid or lubricant when working in cast iron or alloy tool steel to extend tool life and improve finish quality. Run the spindle at a speed appropriate for the workpiece material and head diameter to avoid overheating the cutting edges. Wear proper eye protection and ensure the workpiece is clamped securely before operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenterline Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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: 0.5 inches (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\u003ePilot Included\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Alloy Tool 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: C46224\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51698988253490,"sku":"C46224","price":85.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/10402b75d85d1ed57c403d7363990c43.jpg?v=1788370785","url":"https:\/\/voomisupply.com\/products\/cleveland-c46224-countersink-0-75-in-90-degree-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
