Part of the Series 3189 product line, it features a FIREX finish that improves heat resistance and extends tool life in demanding cutting conditions. The 4-flute, right-hand cut geometry with right-hand flutes and a 20-degree helix angle delivers efficient chip evacuation and a smooth surface finish. The centercutting design allows plunge entry, giving machinists flexibility in toolpath programming. This end mill is installed and operated by CNC machinists, tool-and-die makers, and precision metalworking professionals.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for finish milling, slotting, profiling, and light plunge operations on machining centers and CNC mills. The fine pitch, regular-length configuration makes it appropriate for general-purpose work in shop environments where consistent dimensional accuracy is required. Its 0.25 inch diameter and 0.75 inch length of cut handle tight-tolerance features in mold work, fixture fabrication, and production part machining.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eFIREX coating enhances thermal resistance and extends tool life\u003c\/li\u003e\n\u003cli\u003e4-flute, right-hand cut with right-hand flute orientation\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry\u003c\/li\u003e\n\u003cli\u003e20-degree helix angle promotes efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eFine pitch geometry for smooth surface finish\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard shank end mill for use in ER collet chucks, end mill holders, and shrink-fit toolholders accepting a 0.25 inch shank diameter on CNC machining centers and manual mills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes must be performed with the machine spindle fully stopped and the control in a safe state. Secure the 0.25 inch shank in a clean, properly sized collet or holder, torquing to the toolholder manufacturer's specification. Inspect the cutting edges and coating for chips or wear before each use. Follow shop safety standards and machine-specific operating procedures when setting tool length offsets and running first-article cuts.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut (LOC)\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 20 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Style\u003c\/strong\u003e: Square, Single End\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\u003ePitch\u003c\/strong\u003e: Fine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: FIREX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\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\u003eWeight\u003c\/strong\u003e: 1.45 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: GUHRING\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9031890063500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51748842406194,"sku":"9031890063500","price":120.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4de130c07b78f98d9ba9f17a7ca2d431.jpg?v=1788899393","url":"https:\/\/voomisupply.com\/products\/guhring-9031890063500-square-end-mill-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
