Built on GUHRING Series 3182, it features a FIREX coating and a 55-degree helix angle that promotes efficient chip evacuation and thermal resistance at the cutting edge. The 0.25-inch diameter pairs with a 0.75-inch length of cut, making this a compact but capable tool for finishing and semi-finishing passes. Centercutting geometry allows plunge entry. This end mill is installed and operated by CNC machinists and tool-and-die professionals working on close-tolerance components.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for milling hard steels, hardened tool steels, and cast iron in both production and job-shop environments. The straight cylindrical shank accepts standard collet chucks and hydraulic toolholders sized for a 0.25-inch bore. Its regular-length profile fits most vertical machining center setups where clearance is not a limiting factor. The right-hand cut and right-hand spiral flute configuration is standard for conventional CNC milling spindles.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e6-flute geometry increases feed rate capability and surface finish quality in hard materials\u003c\/li\u003e\n\u003cli\u003eFIREX coating provides heat and wear resistance for extended tool life in ferrous alloys\u003c\/li\u003e\n\u003cli\u003e55-degree helix angle promotes smooth cutting action and chip flow\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge milling without a pilot hole\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction delivers rigidity and dimensional stability under high cutting loads\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute configuration compatible with standard CNC spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers and milling machines accepting a 0.25-inch straight cylindrical shank.

Secure the shank in a collet chuck or hydraulic toolholder to the full recommended grip length before use; do not expose more shank than necessary. Confirm spindle rotation direction matches the right-hand cut specification before starting the program. Follow machine tool manufacturer torque specifications for drawbar and toolholder retention.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.25 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\u003eLength of Cut\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 55 degrees\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\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: h10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Hard Material (Code H)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Cast Iron (Code K)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 3182\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: 9031820063500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51754846454066,"sku":"9031820063500","price":77.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/971607311c53a940cc74431800ce4ec2.jpg?v=1788949162","url":"https:\/\/voomisupply.com\/products\/guhring-9031820063500-square-end-mill-1-4-in-6-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
