Built from M42 cobalt high-speed steel, it delivers heat and wear resistance suited to demanding materials. The ball-nose geometry produces contoured and profiled surfaces in a single pass. At 0.1875 inches in diameter with a 0.5-inch length of cut, this tool is sized for fine detail work where precision matters. A 30-degree helix angle promotes smooth chip evacuation and reduces cutting forces. Licensed machinists and tool-and-die professionals are the primary installers of this end mill series.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for finishing passes on stainless steel and steel workpieces in both manual and CNC milling setups. The 4-flute spiral configuration and uncoated M42 cobalt construction make it a practical choice for shops that require consistent surface finish on ferrous alloys. The 3\/8-inch shank diameter fits standard collets and end mill holders found on vertical machining centers and knee mills. The regular-length profile keeps deflection low in confined pockets and contoured geometry work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt construction for elevated heat resistance on stainless steel and alloy steels\u003c\/li\u003e\n\u003cli\u003eBall-nose geometry for contoured surface finishing and profiling\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle promotes smooth chip flow and reduced cutting pressure\u003c\/li\u003e\n\u003cli\u003e4-flute spiral design supports fine surface finish at finishing feed rates\u003c\/li\u003e\n\u003cli\u003eSingle-end configuration with right-hand cut and right-hand flute direction\u003c\/li\u003e\n\u003cli\u003eUncoated finish — compatible with coolant flood applications standard to most shop setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 3\/8-inch collets and end mill holders on CNC vertical machining centers and conventional knee mills.

Secure the shank in a properly sized collet or end mill holder torqued to the machine manufacturer's specification. Confirm runout with a dial indicator before beginning a finishing pass. This tool is intended for finishing operations — avoid using it as a roughing tool, as doing so may accelerate wear on the ball-nose geometry.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.1875 inches\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\u003eNumber of Flutes\u003c\/strong\u003e: 4\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)\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\u003eFlute 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\u003eMaterial Removal Type\u003c\/strong\u003e: Finishing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HGC-4B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: C42780\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51717592449330,"sku":"C42780","price":81.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8b0c519ecd182126e1be8d874934f875.jpg?v=1788543017","url":"https:\/\/voomisupply.com\/products\/cleveland-c42780-ball-end-mill-0-1875-in-4-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
