Ground from micrograin solid carbide, it carries a 0.0625 inch cutting diameter and a 0.1875 inch length of cut. The AlTiN coating adds thermal resistance and hardness, allowing higher cutting speeds and longer tool life in dry or semi-dry machining environments. With a 30-degree helix angle and 4-flute geometry, this tool produces smooth surface finishes while maintaining chip clearance in tight pockets and contoured features. It is intended for use by machinists and tool-and-die professionals on CNC mills and machining centers.\u003c\/p\u003e\u003cp\u003eThis end mill suits precision work in mold making, die work, and close-tolerance part machining. The 0.0625 inch diameter makes it well suited for fine detail passes, small radii, and finishing cuts in hardened steel, stainless steel, and high-temperature alloys where AlTiN coating performance is most effective. The 0.125 inch shank diameter fits standard ER and end mill collet holders. The 1.5 inch overall length keeps the tool rigid during high-speed operations, reducing deflection in critical finish passes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.0625 inch ball nose cutting diameter for fine detail and small-radius work\u003c\/li\u003e\n\u003cli\u003eAlTiN coating for high thermal resistance in dry and semi-dry cutting of hard materials\u003c\/li\u003e\n\u003cli\u003e4-flute, right-hand cut and right-hand flute geometry for smooth surface finish\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate for rigidity and edge retention\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle balances chip evacuation and cutting load\u003c\/li\u003e\n\u003cli\u003eSingle-end design for standard collet and end mill holder mounting\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use solid carbide ball end mill for CNC machining centers and manual mills accepting a 0.125 inch shank diameter via ER collet or end mill holder.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following standard tooling and machine safety procedures. Ensure the spindle is fully stopped and machine is in a safe state before changing tooling. Secure the 0.125 inch shank in a clean, properly sized collet or tool holder to the appropriate clamping torque per the holder manufacturer's specification. Inspect the cutting edges and coating before use and discard the tool if chipping or coating delamination is observed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.0625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\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\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3 inches L x 0.3 inches W x 0.3 inches H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\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: EM99924513\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51752253784370,"sku":"EM99924513","price":33.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d80bde93d87dfa2075f9055039eecca6.jpg?v=1788926960","url":"https:\/\/voomisupply.com\/products\/hertel-em99924513-ball-end-mill-0-0625-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
