Built from high speed steel and coated with titanium nitride (TiN), it offers improved surface hardness and heat resistance compared to uncoated HSS tooling. The 0.5-inch diameter cutting end features two flutes with a 30-degree right-hand spiral helix, producing smooth chip evacuation and clean finish cuts. With a 0.8125-inch length of cut and 4.125-inch overall length, this end mill fits standard tool holders with a 0.5-inch shank. It is suited for machinists and toolroom operators running milling machines, CNC machining centers, and manual knee mills.\u003c\/p\u003e\u003cp\u003eThis end mill is engineered for finishing cuts on cast iron, non-ferrous metals, and steel. The double-end configuration extends tool life by providing two usable cutting ends per tool, reducing per-edge cost in production or job-shop environments. The regular-length profile makes it compatible with most standard tool holders without requiring extended-reach setups. It is well suited for profiling, contouring, and slotting operations where a ball nose geometry is required to produce radius features or blended surfaces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTiN coating increases surface hardness and reduces friction for longer tool life in steel and cast iron\u003c\/li\u003e\n\u003cli\u003eDouble-end design provides two cutting ends per tool, maximizing value in production use\u003c\/li\u003e\n\u003cli\u003e30-degree right-hand spiral helix promotes efficient chip evacuation during finish milling\u003c\/li\u003e\n\u003cli\u003eTwo-flute geometry balances chip clearance and edge strength for ball-nose finishing passes\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction allows sharpening and regrinding in a toolroom environment\u003c\/li\u003e\n\u003cli\u003eRegular-length profile fits standard collet chucks and end mill holders without extended reach\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 0.5-inch collet chucks, end mill holders, and milling machine spindles.

Ensure the spindle is fully powered down and locked out before loading or unloading the tool. Secure the 0.5-inch shank in a properly sized collet or end mill holder and verify runout before beginning a cut. Inspect both cutting ends for damage or wear before use, particularly when rotating to the second end on a double-end tool.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5 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\u003eShank Diameter\u003c\/strong\u003e: 0.5 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\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\u003eSingle or Double End\u003c\/strong\u003e: Double\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\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Cast Iron, Non-Ferrous Metal, Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HD-2B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Finishing\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: C39153\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51700027261234,"sku":"C39153","price":159.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5b7dff1411786e833267eed9ce6fea2c.jpg?v=1788385128","url":"https:\/\/voomisupply.com\/products\/cleveland-c39153-ball-end-mill-0-5in-2-flute-hss-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
