It features a 3\/8 inch cutting diameter, a 7\/8 inch length of cut, and a 3-flute geometry with a 30-degree helix angle. The AlTiN coating improves heat resistance and extends tool life in dry or semi-dry cutting conditions. Micrograin carbide construction provides hardness and edge integrity under demanding cutting loads. This end mill is center-cutting, allowing it to plunge directly into a workpiece. It is suited for use in CNC machining centers and manual milling machines operated by machinists and toolroom technicians.\u003c\/p\u003e\u003cp\u003eThis end mill is appropriate for slotting, profiling, and pocket milling in ferrous and non-ferrous materials where a single-end, right-hand cut tool is required. The 3\/8 inch shank diameter fits standard collets and end mill holders common in both production and job-shop environments. The 2-1\/2 inch overall length provides a compact, rigid setup suitable for shallow to medium-depth features. It is sold individually and is well suited for maintenance machining, prototype work, and production runs where consistent chip evacuation and surface finish are priorities.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/8 inch cutting diameter with matching 3\/8 inch shank for direct collet fitment\u003c\/li\u003e\n\u003cli\u003eSolid micrograin carbide construction for hardness and wear resistance\u003c\/li\u003e\n\u003cli\u003eAlTiN finish for elevated heat resistance in dry and semi-dry cutting\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle promotes smooth chip evacuation and reduced cutting forces\u003c\/li\u003e\n\u003cli\u003eCenter-cutting geometry allows direct plunge entry without pre-drilling\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, single-end design with no chipbreaker or variable helix\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or standard tooling option for any milling setup accepting a 3\/8 inch straight shank end mill in an ER collet, end mill holder, or equivalent toolholder.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following the machine tool manufacturer's toolholder torque and runout specifications. Ensure the spindle is fully stopped and the machine is in a safe state before inserting or removing the tool. Minimum stick-out should be used to maximize rigidity and minimize deflection. Verify collet condition and holder cleanliness before clamping to maintain concentricity.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.375 inches (3\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.875 inches (7\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches (3\/8 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\u003eNumber of Flutes\u003c\/strong\u003e: 3\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\u003eFinish\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3.5 inches L x 0.6 inches W x 0.6 inches H\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: 750417\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51747505668402,"sku":"750417","price":67.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/177b5a8b982c07a2a4625c4ea1ad28ad.jpg?v=1788881515","url":"https:\/\/voomisupply.com\/products\/hertel-750417-square-end-mill-3-8-in-3-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
