Built from M42 cobalt high-speed steel, this 6-flute tool delivers a stable, high-productivity cut with a 30-degree right-hand spiral flute geometry. It measures 0.75 inches in diameter with a 4-inch length of cut and a 6.25-inch overall length, placing it in the extra-long reach category. The centercutting design allows plunge entry. It ships uncoated and is intended for machinists and tool room operators working in CNC or manual milling environments.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for slot milling, profiling, and peripheral milling in steel, stainless, and other tough alloys where cobalt tooling outperforms standard high-speed steel. The extra-long length of cut makes it well-suited for deep-pocket milling, tall workpieces, and applications where standard-length end mills fall short. It carries a right-hand cut and right-hand flute configuration, compatible with conventional vertical and horizontal milling setups. No chipbreaker or variable helix features are present, keeping the geometry straightforward for general-purpose work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt construction for heat and wear resistance in tough alloys\u003c\/li\u003e\n\u003cli\u003e6-flute design increases feed rates and surface finish quality in finishing passes\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle promotes smooth chip evacuation and reduced chatter\u003c\/li\u003e\n\u003cli\u003eCentercutting capability allows direct plunge milling without pre-drilling\u003c\/li\u003e\n\u003cli\u003eExtra-long 4-inch length of cut for deep pockets and tall part features\u003c\/li\u003e\n\u003cli\u003eUncoated finish — suitable for re-sharpening or use with cutting fluids\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard-shank square end mill with a 0.75-inch shank diameter, compatible with 3\/4-inch collet chucks, end mill holders, and milling machine spindles configured for that shank size.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist. Secure the shank fully within the holder to the recommended engagement depth before tightening — insufficient shank engagement is a leading cause of tool pull-out and breakage. Ensure the spindle and workholding are locked out before changing tooling. Select speeds and feeds appropriate for the workpiece material and cobalt tooling grade; consult published Speeds and Feeds tables for M42 cobalt end mills.\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\u003eNumber of Flutes\u003c\/strong\u003e: 6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt (M42)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 4 inches (4.0000 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: 6.25 inches\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: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Extra Long\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: 0.504 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: E2175048\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51733231862066,"sku":"E2175048","price":170.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d0e03598f6cf55d57e9b878e028208be_38f694ef-000c-4008-8093-9bc5687aa004.jpg?v=1788753087","url":"https:\/\/voomisupply.com\/products\/hertel-e2175048-square-end-mill-3-4-in-6-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
