Built from high speed steel with an oxide finish, it delivers consistent cutting performance on carbon steel and cast iron workpieces. The tool features a 3\/4 inch head diameter, a 100-degree included angle, and a 1\/2 inch straight-cylindrical shank with an overall length of 2.625 inches. The right-hand cutting direction suits standard drill press, milling machine, and hand-drill setups. Licensed machinists, toolroom technicians, and metalworking tradespeople are the primary users of this countersink.\u003c\/p\u003e\n\u003cp\u003eThe C46177 is suited for countersinking flat-head fastener seats, chamfering drilled holes, and light deburring on carbon steel and cast iron parts. The 100-degree included angle is commonly specified for aerospace and industrial flat-head screw applications where a wider seat angle is required. Its compact 2.625-inch overall length fits standard drill chucks without extension. This countersink is appropriate for both bench-top drill press use and handheld power tool operation in production or maintenance environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/4 inch head diameter with 100-degree included angle for wide-seat countersinking\u003c\/li\u003e\n  \u003cli\u003eThree-flute geometry provides smooth cutting action and good chip clearance\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction handles carbon steel and cast iron workpieces\u003c\/li\u003e\n  \u003cli\u003eOxide coating provides corrosion resistance and reduces built-up edge during cutting\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch straight-cylindrical shank fits standard drill chucks and collet holders\u003c\/li\u003e\n  \u003cli\u003eSingle-end, no-pilot design for versatile use across hole sizes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for countersinking operations on carbon steel and cast iron materials.

Secure the 1\/2 inch shank firmly in the chuck or collet before operation and verify the workpiece is clamped to prevent movement. Use appropriate cutting fluid for carbon steel applications to extend tool life and improve finish quality. Follow all shop safety protocols and machine guarding requirements when operating rotary cutting tools.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 3\/4 inch (0.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 100 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenterline Angle\u003c\/strong\u003e: 50 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: 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\u003eOverall Length\u003c\/strong\u003e: 2.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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: C46177\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51720397357362,"sku":"C46177","price":93.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a4d9a0b51b5987488b126048e9278c4b.jpg?v=1788563374","url":"https:\/\/voomisupply.com\/products\/cleveland-c46177-countersink-3-4-in-100-deg-3-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
