Constructed from M42 cobalt high-speed steel, this tool handles tough ferrous metals and heat-resistant alloys where standard HSS tooling falls short. The 1\/2 inch diameter cutter features 4 flutes with a coarse pitch geometry that breaks chips into smaller segments, reducing heat buildup and cutting forces. A titanium nitride (TiN) coating adds surface hardness and lubricity, extending tool life in production environments. The 1 inch length of cut and 3 inch overall length suit it for typical side-milling and slotting passes on vertical or horizontal machining centers.\u003c\/p\u003e\n\u003cp\u003eThis roughing end mill is suited for job shops, tool rooms, and production machining cells running steel, stainless, and similar materials. The coarse-pitch flute design excels in hogging operations where feed rates and depth of cut are prioritized over surface finish. Right-hand cut and right-hand flute direction make it compatible with standard spindle setups. Because this tool is not center-cutting, it is not intended for direct plunge entry. It is typically used in setups where ramping, helical interpolation, or a pre-drilled entry point is used before lateral engagement.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt steel construction for elevated heat and wear resistance in tough alloys\u003c\/li\u003e\n  \u003cli\u003eTiN coating increases surface hardness and reduces friction during high-feed cuts\u003c\/li\u003e\n  \u003cli\u003eCoarse pitch, 4-flute geometry promotes aggressive chip breaking and material removal\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch shank diameter matches standard collet and end mill holder sizes\u003c\/li\u003e\n  \u003cli\u003eSingle-end design with 1 inch length of cut and 3 inch overall length\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute for use in standard CNC and manual mill spindles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 1\/2 inch collet chucks, end mill holders, and milling arbors on vertical machining centers, horizontal mills, and manual knee mills.

Ensure the spindle is fully stopped and locked before loading or removing the tool from the holder. Verify runout with a dial indicator after seating the shank to minimize vibration and premature edge wear. Follow machine manufacturer guidelines and applicable shop safety standards when setting cutting parameters for cobalt tooling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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: TiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 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\u003ePitch\u003c\/strong\u003e: Coarse\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\u003eCenter Cutting\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 to -0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.00394 to -0.00197 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 4.88 inches L x 0.71 inches W x 0.59 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0185 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 44839124\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51731874644274,"sku":"44839124","price":64.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5e8c64fc705637ab86606148b1b45613.jpg?v=1788735942","url":"https:\/\/voomisupply.com\/products\/hertel-44839124-roughing-end-mill-1-2-in-4-flute-cobalt-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
