Built from high speed steel and coated with titanium nitride (TiN) for extended tool life, this end mill measures 0.4375 inches in diameter with a 0.8125-inch length of cut and a 4.125-inch overall length. The 2-flute, right-hand spiral configuration at a 30-degree helix angle promotes efficient chip evacuation during contouring and profiling passes. Installed by machinists and tool-and-die professionals, the C39152 is a reliable choice for precision finishing on a range of ferrous and non-ferrous workpieces.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for finishing cuts on cast iron, non-ferrous metals, and steel. The double-end design offers two usable cutting ends, extending the service life of each tool before replacement is needed. The 0.5-inch shank diameter fits standard collet and end mill holders commonly found in vertical machining centers and manual knee mills. Its regular length classification makes it appropriate for general-purpose setups where extended reach is not required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTiN coating increases surface hardness and reduces friction for longer cutting life\u003c\/li\u003e\n\u003cli\u003eDouble-end design provides two cutting ends per tool\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle promotes smooth chip flow during finishing passes\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute spiral for standard machining setups\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction suitable for cast iron, non-ferrous metals, and steel\u003c\/li\u003e\n\u003cli\u003eSeries HD-2B designation for consistent tooling library management\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a finishing end mill compatible with standard 0.5-inch collet and end mill holder systems used in vertical machining centers, knee mills, and CNC milling setups.

Verify that the collet or end mill holder is clean and undamaged before seating the shank. Torque the retention mechanism according to the machine tool manufacturer's specifications. Confirm runout with a dial indicator before beginning a finishing pass to avoid dimensional error or premature tool wear.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.4375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.8125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\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\u003eEnd Mill Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN (Titanium Nitride)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Double End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Non-Ferrous Metal, Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Finishing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HD-2B\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: C39152\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51698139595058,"sku":"C39152","price":159.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1266d51edcc50d9d4d951d1a9b9e4eae.jpg?v=1788358335","url":"https:\/\/voomisupply.com\/products\/cleveland-c39152-ball-end-mill-0-4375-in-2-flute-hss-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
