It features a 1\/4-inch cutting diameter, a 3\/4-inch length of cut, and a 2.5-inch overall length with a 1\/4-inch straight cylindrical shank. The four-flute, right-hand helical design incorporates a variable helix angle ranging from 35 to 38 degrees, which reduces harmonic vibration and chatter during aggressive cuts. A FIREX coating provides elevated heat resistance and extended tool life compared to uncoated carbide. This end mill is centercutting, allowing plunge entry into the workpiece. It is intended for use by machinists and tooling professionals working in CNC and manual milling operations.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for milling cast iron, stainless steel, carbon steel, and superalloys, corresponding to material codes K, M, P, and S, with secondary capability in hard materials (code H). It fits standard 1\/4-inch collets and tool holders used in vertical machining centers, CNC mills, and manual knee mills. The standard-length geometry makes it a practical choice for general-purpose slotting, profiling, and peripheral milling where reach requirements are moderate. It is part of GUHRING Series 19959.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eVariable helix angles of 35 and 38 degrees reduce chatter and improve surface finish\u003c\/li\u003e\n  \u003cli\u003eFIREX coating enhances wear resistance and performance in hard and exotic materials\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction provides rigidity and thermal stability at high cutting speeds\u003c\/li\u003e\n  \u003cli\u003eCentercutting design permits direct plunge milling without a pre-drilled entry point\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute with helical flute geometry for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eMill diameter tolerance e8 and shank diameter tolerance h6 for precise tool holder fit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with standard 1\/4-inch collet chuck systems and end mill holders.

Ensure the spindle is fully stopped and the machine is locked out before installing or removing the end mill. Seat the shank fully into the collet or tool holder and torque the retaining nut to the tool holder manufacturer's specification. Verify runout with a dial indicator before beginning a production cut, as excessive runout will accelerate wear on a variable-helix carbide tool.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.25 inches (1\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.75 inches (3\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches (1\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Helical\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\u003eVariable Helix\u003c\/strong\u003e: Yes (35 degrees minimum, 38 degrees maximum)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\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\u003eSingle or Double End\u003c\/strong\u003e: Single end\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\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\u003eMill Diameter Tolerance\u003c\/strong\u003e: e8\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 Codes\u003c\/strong\u003e: K, M, P, S\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Hard material (code H)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 19959\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 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: 9199590063500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51730517164338,"sku":"9199590063500","price":52.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/37f44bd991618faeee1f0ce0826503e2_829af766-aea6-4dad-bfe0-9bc4d857c671.jpg?v=1788718838","url":"https:\/\/voomisupply.com\/products\/guhring-9199590063500-square-end-mill-1-4-inch-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
