Constructed from M42 cobalt high-speed steel, it delivers improved heat and wear resistance compared to standard M2 tooling. The cutter measures 0.375 inches in diameter with a 1.5-inch length of cut and a 3.25-inch overall length. A 30-degree helix angle promotes smooth chip evacuation and reduced cutting forces. The uncoated finish makes it easy to resharpen, extending tool life in appropriate applications. Installation is handled by machinists and CNC operators in metalworking shops.\u003c\/p\u003e\n\u003cp\u003eThis end mill fits standard milling machines, machining centers, and CNC mills using 3\/8-inch collets, end mill holders, or set-screw style tool holders. The long-series length of cut range of 1.5 to 2.0 inches suits applications requiring extended reach into pockets, slots, and step features. Right-hand cut and right-hand spiral flute geometry is compatible with conventional spindle rotation. The single-end configuration is typical for indexing and reconditioning workflows. This tool is suited for slotting, peripheral milling, and plunge cuts in ferrous workpieces where cobalt tooling is specified.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt high-speed steel construction for elevated heat resistance and edge retention\u003c\/li\u003e\n  \u003cli\u003e4-flute, spiral flute geometry with 30-degree helix angle for smooth chip flow\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute direction for standard spindle setups\u003c\/li\u003e\n  \u003cli\u003eUncoated finish supports resharpening and regrinding by tool service shops\u003c\/li\u003e\n  \u003cli\u003eLong-series classification with 1.5-inch length of cut for extended-reach applications\u003c\/li\u003e\n  \u003cli\u003eSingle-end design with matched 3\/8-inch shank and cutter diameter for direct collet clamping\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 3\/8-inch end mill holders, collet chucks, and set-screw holders on manual mills and CNC machining centers.

Verify spindle rotation direction is right-hand before starting the cut. Inspect the collet or holder bore for chips and wear before each tool change to maintain runout within acceptable limits. This tool does not include centercutting geometry and should not be used for direct plunge drilling without a pre-drilled entry.\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 inches (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.5 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: 3.25 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: Cobalt (M42 HSS)\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\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Long\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut Range\u003c\/strong\u003e: 1.5 to 2.0 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.504 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: E2034024\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51748647698738,"sku":"E2034024","price":44.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b3d112a63abad2400fe2394d3293d8fc.jpg?v=1788896160","url":"https:\/\/voomisupply.com\/products\/hertel-e2034024-square-end-mill-3-8-in-4-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
