Built from micrograin solid carbide and coated with AlTiN (aluminum titanium nitride), it handles high-heat applications where tool life and surface finish are critical. The 0.375-inch cutting diameter and 4-flute geometry deliver efficient chip evacuation and smooth finishes in profiling, contouring, and slotting work. The 30-degree helix angle balances cutting force and chip flow across a 1-inch length of cut. This tool is suited for use in CNC machining centers and manual mills operated by machinists and tool-and-die professionals.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use in shop environments requiring tight-tolerance milled profiles in hardened steels, stainless, titanium, and similar materials where AlTiN coating provides thermal resistance. The 3\/8-inch shank diameter fits standard collets and end mill holders. The 2.5-inch overall length provides adequate reach for most standard workpiece setups without excessive overhang. Right-hand cut and right-hand flute direction make this a conventional configuration compatible with standard CNC spindle setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eAlTiN coating provides thermal barrier for high-speed dry or semi-dry cutting\u003c\/li\u003e\n\u003cli\u003e4-flute design improves surface finish and feed rate capacity over 2-flute options\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle balances cutting forces and promotes chip evacuation\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute, single-end configuration\u003c\/li\u003e\n\u003cli\u003eBall nose profile suited for 3D contour milling and radius floor features\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or standard selection for CNC machining centers and manual mills accepting a 3\/8-inch straight shank end mill holder or collet.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following standard toolholding procedures. Ensure the spindle is fully stopped and the machine is in an e-stop or locked-out state before inserting or removing the tool. Seat the shank fully in the collet or holder to the recommended engagement depth per the toolholder manufacturer guidelines. Minimize overhang beyond what the job requires to reduce vibration and deflection.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.375 inches\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: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\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: 3.5 x 0.6 x 0.6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: EM250024\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51747622617394,"sku":"EM250024","price":74.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f74925e893d57820acd39e7c0dd05b35.jpg?v=1788883611","url":"https:\/\/voomisupply.com\/products\/hertel-em250024-ball-end-mill-0-375-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
