Built to Series 3366 specifications, it features a 0.3937 inch (10 mm) cutting diameter, a 0.8661 inch (22 mm) length of cut, and a variable helix angle of 40 to 42 degrees. The FIREX coating provides enhanced heat resistance and extended tool life in demanding cutting environments. With four flutes and a right-hand spiral configuration, this single-end mill delivers consistent chip evacuation and surface finish. It is center-cutting capable, allowing plunge entry where required. Installed by machinists and toolroom professionals, this end mill suits CNC machining centers and manual mills alike.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for high-performance milling applications where tool rigidity and coating durability are critical. The solid carbide construction and FIREX finish make it well-suited for harder workpiece materials and higher cutting speeds. The 0.3937 inch shank diameter matches the cutting diameter for straightforward toolholder compatibility. The overall length of 72 mm (approximately 2.835 inches) keeps the tool compact for improved rigidity in standard depth-of-cut applications. Typical use cases include side milling, slotting, and profiling on CNC machining centers in job shop and production environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for high stiffness and wear resistance\u003c\/li\u003e\n  \u003cli\u003eFIREX coating for elevated heat resistance and extended tool life\u003c\/li\u003e\n  \u003cli\u003eVariable helix angle of 40 to 42 degrees reduces chatter and improves surface finish\u003c\/li\u003e\n  \u003cli\u003eFour right-hand spiral flutes with center-cutting capability\u003c\/li\u003e\n  \u003cli\u003eSingle-end design with 0.3937 inch shank diameter for standard ER and hydraulic toolholders\u003c\/li\u003e\n  \u003cli\u003eSeries 3366 regular length type for balanced reach and rigidity\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style solid carbide square end mill suitable for standard 10 mm collet chucks, ER toolholders, and hydraulic chucks used in CNC machining centers and manual knee mills.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and the tool changer or spindle lock is engaged before inserting or removing the end mill. Use a properly sized collet or toolholder matched to the 0.3937 inch shank diameter and torque the retention mechanism according to the toolholder manufacturer specifications. Inspect the cutting edges for chips or damage before each use and replace the tool if edge integrity is compromised.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.3937 inches (10 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.8661 inches (22 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3937 inches (10 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 72 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 to 42 degrees (variable)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: FIREX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 3366\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Proprietary\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.064 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: GUHRING\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9033660100000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51731081167154,"sku":"9033660100000","price":290.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fb1f5c5ba8aee25ef42cd84c4a2fd62e.jpg?v=1788726745","url":"https:\/\/voomisupply.com\/products\/guhring-9033660100000-square-end-mill-0-3937-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
