Built from M42 cobalt high-speed steel, this single-end mill offers improved heat and wear resistance compared to standard HSS tooling. The 0.1875-inch diameter cutting geometry and 30-degree right-hand spiral helix promote smooth chip evacuation and reduced cutting forces. The uncoated finish makes it well suited for materials where coating adhesion or thermal buildup is a concern. Licensed machinists and tooling professionals use this series for tight-tolerance profiling, contouring, and finishing passes where surface finish quality is the priority.\u003c\/p\u003e\n\u003cp\u003eThe C42645 belongs to the HGC-2B series, a regular-length line engineered primarily for finishing cuts in stainless steel and carbon steel. With a 0.5-inch length of cut and a 3\/8-inch shank diameter, it fits standard collet chucks and end mill holders found on vertical machining centers, CNC mills, and manual knee mills. The 2-3\/8-inch overall length keeps deflection low during close-tolerance work. This tool is suited for job shops, maintenance departments, and production environments where consistent finish quality on ferrous materials is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt HSS construction provides elevated heat resistance for stainless steel and alloy steel cutting\u003c\/li\u003e\n  \u003cli\u003e30-degree right-hand spiral helix promotes efficient chip evacuation and smooth cutting action\u003c\/li\u003e\n  \u003cli\u003eBall end geometry enables profiling, contouring, and 3D surface finishing\u003c\/li\u003e\n  \u003cli\u003eUncoated finish suitable for ferrous materials where coating is not required\u003c\/li\u003e\n  \u003cli\u003eSingle-end, regular-length design minimizes deflection in finishing applications\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction compatible with standard spindle rotation on most mill platforms\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard tooling option for use in 3\/8-inch collet chucks, ER collets, and end mill holders on vertical machining centers and manual milling machines.

Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the 3\/8-inch shank fully into the holder and torque the collet nut or set screw to the tool holder manufacturer's specification. Verify runout with a dial indicator before beginning a cut, as excessive runout accelerates wear on small-diameter end mills.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt (M42 HSS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HGC-2B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\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: C42645\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51691328733490,"sku":"C42645","price":52.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1785c29b3a35b054d79fbee546a5f28e.jpg?v=1788283313","url":"https:\/\/voomisupply.com\/products\/cleveland-c42645-ball-end-mill-0-1875-in-2-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
