Built from M42 cobalt high-speed steel, this tool handles tough ferrous and non-ferrous materials where standard HSS tooling falls short. The 1\/2 inch diameter cutter features 3 flutes with a coarse pitch geometry, producing a ripping or wave-form cut that breaks chips efficiently and reduces cutting forces. The bright, uncoated finish suits applications where coating adhesion or heat management from a coating is not required. This end mill is center-cutting, allowing plunge cuts as well as peripheral milling. Machinists and tool-and-die professionals working with manual mills, CNC machining centers, and knee mills are the primary users.\u003c\/p\u003e\u003cp\u003eThis roughing end mill is suited for slotting, profiling, and pocketing operations where high metal removal rate is the priority over finish quality. The coarse pitch flute design is particularly effective on steels, stainless alloys, and cast iron where chip evacuation is critical. With a 1-5\/8 inch length of cut and 3-5\/8 inch overall length, the tool fits standard milling chucks and collet holders sized for 1\/2 inch shank tooling. Right-hand cutting and right-hand flute direction make this a direct fit for conventional spindle rotation setups found in most shop environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt HSS construction for improved hardness and heat resistance over standard M2 tooling\u003c\/li\u003e\n\u003cli\u003e3-flute coarse pitch geometry for aggressive chip breaking and reduced cutting forces\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design allows direct plunge entry without pre-drilling\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for general-purpose roughing without coating buildup concerns\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction for standard spindle setups\u003c\/li\u003e\n\u003cli\u003eMatched 1\/2 inch shank and cutter diameter for straightforward collet or chuck mounting\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit roughing end mill for standard 1\/2 inch collet holders, end mill holders, and milling chucks used in vertical and horizontal milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists familiar with milling tooling and machine setup. Ensure the spindle is fully stopped and the machine is powered down before inserting or removing the end mill. Seat the shank fully in the collet or holder to the recommended engagement depth before tightening. Follow the machine manufacturer torque specifications for the holder type in use, and verify runout with a dial indicator before beginning a production cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\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\u003eMaterial Grade\u003c\/strong\u003e: M42\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-5\/8 inches (1.6250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 3-5\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single End\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\u003eCenter Cutting\u003c\/strong\u003e: Yes\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\u003eWeight\u003c\/strong\u003e: 0.504 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 91192583\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51738857079090,"sku":"91192583","price":64.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4896df4a1194491ce812903a97dd3dd7.jpg?v=1788805629","url":"https:\/\/voomisupply.com\/products\/hertel-91192583-roughing-end-mill-1-2-in-3-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
