With a 1 inch cutting diameter and a 3 inch length of cut, this tool handles deep slotting, profiling, and peripheral milling operations where reach and rigidity are critical. The micrograin carbide substrate provides wear resistance across a range of workpiece materials. An AlTiN coating improves heat resistance and extends tool life at elevated cutting speeds. Four spiral flutes with a 30-degree helix angle promote efficient chip evacuation and reduce cutting forces, making this end mill well suited for production environments where tool longevity and surface finish consistency matter.\u003c\/p\u003e\n\u003cp\u003eThis end mill is intended for use in vertical and horizontal machining centers as well as CNC milling machines equipped with an ER or CAT toolholder accepting a 1 inch shank. The extra-long overall length of 5.5 inches makes it appropriate for cavities, molds, and fixtures requiring extended reach that standard-length end mills cannot access. Right-hand cut and right-hand flute geometry follows conventional milling machine spindle orientation. The centercutting design allows plunge milling in addition to peripheral and slot cuts, adding versatility to the tool's application range. This tool is typically specified by CNC machinists and tool-and-die professionals in job shop and production environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1 inch cutting diameter with a matching 1 inch shank for a rigid, low-runout setup\u003c\/li\u003e\n  \u003cli\u003e3 inch length of cut supports deep cavity and slot milling without tool change\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating provides thermal resistance and extended tool life at high surface footage\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide substrate delivers hardness and edge retention superior to HSS tooling\u003c\/li\u003e\n  \u003cli\u003e30-degree spiral flute helix angle balances cutting force reduction with chip clearance\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry enables direct plunge entry without pre-drilling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers and manual mills with spindle toolholding systems that accept a 1 inch straight shank, such as ER collet chucks, end mill holders, and Weldon-style holders.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a qualified CNC machinist or toolroom professional. Secure the shank fully within the toolholder to the minimum insertion depth recommended by the holder manufacturer, and verify runout with a dial indicator before cutting. Power down and lock out the spindle before changing tooling. Confirm spindle direction is set to right-hand rotation before engaging the cut, as this is a right-hand tool.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.5 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: Solid Carbide (Micrograin)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\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\u003eWeight\u003c\/strong\u003e: 1.8 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: 750327\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51750571442482,"sku":"750327","price":829.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b4c6dc4382c26dfee4598eb33569a41d.jpg?v=1788916842","url":"https:\/\/voomisupply.com\/products\/hertel-750327-square-end-mill-1-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
