Built from M7 high speed steel, it features a 3\/8 inch cutting diameter, a 3\/4 inch length of cut, and a 30-degree helix angle with three right-hand spiral flutes. The uncoated finish makes it well suited for applications where regrinding or reconditioning is part of the shop workflow. This tool is center-cutting, allowing plunge entry directly into the workpiece without a pre-drilled starting hole. Machinists and tool-and-die professionals are the primary installers and users of this tool.\u003c\/p\u003e\n\u003cp\u003eThis end mill is used in vertical milling machines, knee mills, and CNC machining centers for slotting, profiling, and peripheral milling of ferrous and non-ferrous materials. The 3\/8 inch shank diameter fits standard R8, ER, or side-lock toolholders of the same bore size. With a 2-1\/2 inch overall length and no extended reach, it is best suited for shallow-to-mid-depth features where rigidity and chatter resistance are priorities. The right-hand cut and right-hand flute configuration follows standard convention for the majority of vertical milling setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8 inch cutting diameter with matching 3\/8 inch shank for direct collet or side-lock mounting\u003c\/li\u003e\n  \u003cli\u003eM7 high speed steel construction provides good toughness and wear resistance at moderate cutting speeds\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle promotes smooth chip evacuation and reduces cutting forces\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting geometry allows direct plunge milling without a pilot hole\u003c\/li\u003e\n  \u003cli\u003eThree-flute design balances chip clearance and edge strength for slotting and profiling\u003c\/li\u003e\n  \u003cli\u003eUncoated finish supports easy regrinding and reconditioning in-house\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard tooling selection for vertical mills and CNC machining centers accepting 3\/8 inch shank end mills in R8, ER collet, or side-lock toolholding systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tool is installed and operated by machinists and CNC operators following standard shop safety procedures. Power down and lock out the spindle drive before seating or removing the tool from the holder. Verify runout with a dial indicator after toolholder engagement to minimize premature edge wear. Do not exceed the recommended depth of cut for the material being machined, and ensure the toolholder bore matches the 3\/8 inch shank diameter exactly before tightening.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/4 inch (0.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eEnd Mill Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: E1043024\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51746539733298,"sku":"E1043024","price":35.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b26839bca91be473e1750dfb57e567d7.jpg?v=1788871116","url":"https:\/\/voomisupply.com\/products\/hertel-e1043024-square-end-mill-3-8-in-3-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
