It carries a 0.375 inch cutting diameter, a 2.25 inch length of cut, and a 4 inch overall length, placing it in the extra-long category for reach-critical operations. The variable helix design, alternating between 36 and 38 degrees, reduces harmonic chatter and improves surface finish at higher feed rates. A nano-A coating provides wear resistance and heat management during continuous cuts. This tool is intended for machinists and CNC operators working with production-grade milling equipment.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for vertical machining centers and CNC knee mills running stainless steel and carbon steel workpieces. The extra-long length of cut makes it appropriate for deep-pocket milling, slotting, and profiling where standard-length tools cannot reach. The straight-cylindrical shank with h6 tolerance provides accurate tool holder seating in ER collets, Weldon holders, and shrink-fit systems. Secondary application extends to cast iron. It is a single-end, center-cutting tool, enabling both plunge entry and conventional peripheral cuts without a pre-drilled pilot.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eVariable helix at 36 and 38 degrees reduces chatter and improves chip evacuation\u003c\/li\u003e\n  \u003cli\u003enano-A coating enhances wear resistance for stainless steel and steel cutting\u003c\/li\u003e\n  \u003cli\u003eExtra-long length of cut at 2.25 inches suits deep-pocket and reach-critical operations\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting geometry allows direct plunge entry without a starter hole\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction maintains rigidity and edge integrity at elevated cutting speeds\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flutes with right-hand cut orientation for standard CNC spindle use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard straight-bore tool holders accepting a 0.375 inch cylindrical shank; primary workpiece materials are stainless steel and steel, with secondary compatibility for cast iron per GUHRING Series 4259 application data.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and setup should be performed by a qualified machinist or CNC tooling technician. Ensure the spindle is fully stopped and the machine is in an e-stop or lockout state before loading the tool. Verify runout at the tool holder with a dial indicator before cutting; excessive runout will accelerate edge wear on carbide tooling. Do not exceed the manufacturer-recommended depth of cut or feed rate for the workpiece material being machined.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.375 inches (h10 tolerance)\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: 2.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches (h6 tolerance)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 36 and 38 degrees (variable)\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\u003eEnd Type\u003c\/strong\u003e: Single End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Extra Long\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003c\/strong\u003e: nano-A\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 4259\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.039 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: GUHRING\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9042590095200\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51730248106290,"sku":"9042590095200","price":218.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9bbd8f3ddf5ab910cd204277ed7895f9.jpg?v=1788714052","url":"https:\/\/voomisupply.com\/products\/guhring-9042590095200-square-end-mill-0-375in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
