It is manufactured from high speed steel (HSS) with a bright, uncoated finish and a 30-degree helix angle. The 7\/32-inch cutting diameter and 1-1\/4-inch length of cut make it well-suited for slotting, profiling, and peripheral milling operations on manual mills and CNC machining centers. The right-hand cutting and right-hand flute direction are standard for conventional milling applications. Machinists and toolroom technicians working in job shops, maintenance facilities, and production environments are the primary users of this tool.\u003c\/p\u003e\u003cp\u003eThis end mill fits applications requiring a 3\/8-inch shank diameter collet or end mill holder. With a 3-1\/16-inch overall length, it provides adequate reach for most standard workholding setups. The non-centercutting geometry means this tool is intended for peripheral and side milling rather than direct plunge cutting. It is appropriate for use on ferrous metals, alloys, and plastics where HSS tooling is specified over carbide, particularly in lower-speed or interrupted-cut conditions.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e7\/32-inch (0.2188-inch) cutting diameter with 1-1\/4-inch length of cut\u003c\/li\u003e\n\u003cli\u003e4-flute spiral flute design for improved surface finish and chip evacuation\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle for balanced cutting forces on common work materials\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction suitable for low-to-moderate speed milling\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish — no coating to account for in speeds and feeds calculations\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute — compatible with standard spindle rotation\u003c\/li\u003e\n\u003cli\u003eNon-centercutting geometry; designed for side milling and profiling, not plunge entry\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in any 3\/8-inch collet, end mill holder, or milling chuck on manual knee mills, CNC vertical machining centers, and toolroom mills that accept standard straight-shank end mills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a clean, properly sized 3\/8-inch collet or end mill holder — inspect for wear or runout before seating the tool. Power down the machine and lock out the spindle drive before inserting or removing the end mill. Torque the collet nut or set screw to the toolholder manufacturer's specification. Confirm runout with a dial indicator after clamping, as excessive runout will accelerate tool wear and degrade surface finish.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 7\/32 inches (0.2188 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-1\/4 inches (1.2500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-1\/16 inches (3.0625 inches)\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\u003eFinish\u003c\/strong\u003e: Bright, Uncoated\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\u003eCentercutting\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 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: E199921260\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51738881851698,"sku":"E199921260","price":44.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ef422124d9be6e7cdef2f0dc1b6a523c.jpg?v=1788806106","url":"https:\/\/voomisupply.com\/products\/hertel-e199921260-square-end-mill-7-32-in-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
