It carries a 3\/4 inch cutting diameter with a 1-5\/8 inch length of cut and a 3-3\/4 inch overall length. The 3\/4 inch shank diameter matches the cutting diameter for straightforward tool-holder setup. The spiral flute geometry runs at a 30-degree helix angle with a right-hand cut and right-hand flute orientation. This tool is uncoated and suited for general-purpose milling in ferrous and non-ferrous materials where HSS tooling is specified. Machinists and tool-room operators working on manual or CNC mills are the primary users.\u003c\/p\u003e\u003cp\u003eThis end mill is appropriate for slotting, profiling, and peripheral milling operations in job-shop, maintenance, and production environments. The 1-5\/8 inch length of cut falls within the 1.5 to 2.0 inch length-of-cut range for this tool class, giving adequate reach for moderate-depth passes. It is not a centercutting design, so plunge cuts are not a recommended application. Best practice is to use it for side milling and conventional slotting where the square end geometry produces a clean, flat-bottomed feature.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/4 inch cutting diameter with matching 3\/4 inch shank diameter for direct collet or end-mill-holder mounting\u003c\/li\u003e\n\u003cli\u003eM7 high speed steel construction for durability in general-purpose milling applications\u003c\/li\u003e\n\u003cli\u003e4-flute configuration balances chip clearance and surface finish in most ferrous materials\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle spiral flute promotes smooth cutting action and efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute — standard orientation for conventional mill spindles\u003c\/li\u003e\n\u003cli\u003eUncoated finish allows easy resharpening by a qualified tool grinder\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 3\/4 inch shank square end mill compatible with collet chucks, side-lock holders, and hydraulic tool holders sized for 3\/4 inch shank tooling on vertical or horizontal milling machines.

Secure the shank fully within the tool holder to the minimum engagement depth recommended by the holder manufacturer before tightening. Confirm spindle rotation direction matches the right-hand cut orientation of this tool before starting the machine. Inspect the tool and holder for runout with a dial indicator after setup to maintain dimensional accuracy and tool life.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/4 inch (0.7500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-5\/8 inch (1.6250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inch (0.7500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: High Speed Steel, Grade M7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single End, Square\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.42 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: E103104801\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51753959850290,"sku":"E103104801","price":75.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/54784bab68a7cba6d35bff09e7899e00.jpg?v=1788942334","url":"https:\/\/voomisupply.com\/products\/hertel-e103104801-square-end-mill-3-4-in-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
