Built from M42 cobalt high-speed steel with a TiAlN coating, it handles tough ferrous and stainless alloys at elevated cutting temperatures. The 9\/16 inch (0.5625 inch) cutting diameter pairs with a 1\/2 inch shank and a 1-3\/8 inch length of cut, giving machinists a solid reach-to-rigidity ratio for roughing passes. Four right-hand spiral flutes with a fine pitch profile break chips effectively and reduce chatter during high-feed cuts. This tool is installed by machinists and toolroom technicians in manual and CNC milling setups.\u003c\/p\u003e\u003cp\u003eThis roughing end mill is suited for roughing and semi-finishing operations on steel, alloy steel, stainless steel, and similar hard materials where heat resistance and edge retention are priorities. The fine pitch geometry and TiAlN coating make it a practical choice for production milling on vertical machining centers and knee mills where tool life under sustained cutting loads is a concern. The non-centercutting design means plunge entry is not supported; ramp or helical entry is required when cutting into a solid surface.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt HSS construction for heat resistance in tough alloy and stainless applications\u003c\/li\u003e\n\u003cli\u003eTiAlN coating extends tool life at elevated surface speeds and reduces built-up edge\u003c\/li\u003e\n\u003cli\u003e4 right-hand spiral flutes with fine pitch for efficient chip evacuation on roughing cuts\u003c\/li\u003e\n\u003cli\u003e9\/16 inch cutting diameter with 1\/2 inch shank for standard ER and side-lock holders\u003c\/li\u003e\n\u003cli\u003e1-3\/8 inch length of cut (1.3750 inches) suits typical roughing depth requirements\u003c\/li\u003e\n\u003cli\u003eNon-centercutting geometry — ramp or helical entry required, no direct plunge\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct drop-in for 1\/2 inch shank roughing end mill applications in standard milling chucks, ER collet holders, and side-lock tool holders on vertical machining centers and manual mills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a machinist or toolroom technician. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the 1\/2 inch shank fully in the holder and torque the retention mechanism per the tool holder manufacturer specification. Confirm runout with a dial indicator before taking the first cut, and verify that the programmed entry path uses ramp or helical engagement — direct plunge cuts are not supported by this non-centercutting geometry.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter (Fractional)\u003c\/strong\u003e: 9\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter (Decimal)\u003c\/strong\u003e: 0.5625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.3750 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 3-3\/8 inches\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\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Fine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\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: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\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\u003ePackage Dimensions\u003c\/strong\u003e: 3.75 x 0.75 x 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 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: 62913637\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51727153824050,"sku":"62913637","price":76.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c4d337705b92a468705bcd672e59dcc0.jpg?v=1788674086","url":"https:\/\/voomisupply.com\/products\/hertel-62913637-roughing-end-mill-9-16-in-4-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
