Built from high speed steel with an oxide coating, it features a 60-degree included angle and a 5\/8-inch head diameter, making it a standard choice for machine screws and fastener seat preparation. The straight cylindrical shank measures 3\/8 inch in diameter for secure chuck or holder engagement. Machinists and toolroom professionals install this countersink in drill presses, CNC machining centers, and manual lathes as part of standard hole-finishing operations.\u003c\/p\u003e\n\u003cp\u003eThis countersink is suited for production and maintenance machining environments where consistent angular seat geometry is required. With a right-hand cutting direction and a single-end configuration, it is appropriate for countersinking fastener holes in ferrous materials including carbon steel and cast iron. The oxide finish helps reduce friction and provides moderate resistance to heat buildup during cutting operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e60-degree included angle for standard fastener seat profiles\u003c\/li\u003e\n  \u003cli\u003eThree flutes for smooth chip evacuation and stable cutting action\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for durability in ferrous material applications\u003c\/li\u003e\n  \u003cli\u003eOxide coating reduces friction and extends tool life in carbon steel and cast iron\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical 3\/8-inch shank fits standard drill chucks and holders\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, single-end design for conventional machine tool setups\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 fully in the chuck or collet and verify runout before beginning a cut. Reduce spindle speed relative to standard twist drill recommendations when countersinking to prevent chatter and maintain seat geometry. Always power down the machine and confirm the spindle has stopped before changing or adjusting tooling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 5\/8 inch (0.6250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenterline Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single\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\u003eMaterial Application\u003c\/strong\u003e: Carbon Steel, Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncludes Pilot\u003c\/strong\u003e: No\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: C46168\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51690880074034,"sku":"C46168","price":77.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e5aacb79e45b805bd72d5f2e25b98be5.jpg?v=1788276851","url":"https:\/\/voomisupply.com\/products\/cleveland-c46168-countersink-5-8-in-60-degree-3-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
