This single-end, right-hand cut tool features a 0.25-inch diameter with a 1.625-inch length of cut and a 4-inch overall length, placing it in the extra-long category for extended reach applications. The 30-degree helix angle and three-flute spiral configuration promote efficient chip evacuation and smooth cutting action. Machinists and CNC operators working in job shops, toolrooms, and production environments will find this an accurate, reliable option for profiling, slotting, and side milling operations.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for milling a range of workpiece materials including cast iron, steel, non-ferrous metals, and high-temperature alloys, as indicated by its primary material codes K, M, N, and P, with secondary suitability for S-grade superalloys. The extra-long length of cut makes it appropriate for deep-pocket milling, tall-wall profiling, and applications where standard-length tooling cannot reach. The bright, uncoated finish is typical for general-purpose carbide tooling used across varied material types.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction from Guhring proprietary material grade for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eThree-flute spiral design with 30-degree helix angle for balanced chip flow and surface finish\u003c\/li\u003e\n\u003cli\u003eExtra-long 1.625-inch length of cut for deep-pocket and tall-wall applications\u003c\/li\u003e\n\u003cli\u003eCenter-cutting geometry allows plunge entry in addition to peripheral and slot milling\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank with h6 tolerance for consistent tool holding in standard collets and chucks\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish compatible with a broad range of workpiece materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003ePart of the Guhring Series 3169 extra-long square end mill line.

Designed for use with standard 0.25-inch collet chucks, end mill holders, and shrink-fit tooling with a 0.25-inch bore.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator with the machine powered off and in an e-stop or locked-out state before tool changes. Ensure the straight cylindrical shank is fully seated and properly torqued in the tool holder per the holder manufacturer's specifications. Verify runout with a dial indicator before engaging the cut, as excessive runout accelerates carbide tool wear. Do not exceed the tool's rated depth of cut or feed rates for the target material.\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: 1.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eEnd Type\u003c\/strong\u003e: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eLength Type\u003c\/strong\u003e: Extra Long\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 3169\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.037 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: 9031690063500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51755601690930,"sku":"9031690063500","price":78.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c8f60008e41ed54b1f6313e9bd623934.jpg?v=1788956678","url":"https:\/\/voomisupply.com\/products\/guhring-9031690063500-square-end-mill-3-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
