Built from micrograin carbide, it delivers a 1\/4 inch cutting diameter with a 1\/4 inch length of cut and a 45-degree helix angle that promotes chip evacuation and surface finish quality. The three-flute geometry balances chip load and rigidity, making it well suited for slotting, profiling, and side milling at moderate feed rates. With a 4 inch overall length and an extended reach of 2-1\/8 inches, this end mill handles deeper-cavity work without requiring an extended arbor. The bright, uncoated finish suits general-purpose use across a range of ferrous and non-ferrous workpiece materials.\u003c\/p\u003e\u003cp\u003eThis end mill is used in CNC machining centers and manual knee mills for precision part production in job shops, tool rooms, and production environments. The long-length configuration and extended reach make it appropriate for milling pockets, slots, and features where standard-length tools cannot access the full depth. Right-hand cutting and right-hand flute direction are standard for conventional spindle rotation. The single-end design means it is replaced when worn rather than indexed. Machinists and CNC operators in general manufacturing, aerospace component shops, and moldmaking operations commonly use this series for tight-tolerance work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for hardness and wear resistance\u003c\/li\u003e\n\u003cli\u003e45-degree helix angle promotes efficient chip flow and reduced cutting forces\u003c\/li\u003e\n\u003cli\u003eThree flutes for balanced chip load in slotting and profiling cuts\u003c\/li\u003e\n\u003cli\u003eExtended reach of 2-1\/8 inches for deep-cavity and long-reach applications\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand spiral for standard spindle operation\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish compatible with a range of workpiece materials and cutting fluids\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or standard tooling selection for CNC machining centers and manual mills accepting a 1\/4 inch round shank.

The machine spindle must be fully stopped and the tool holder cleaned before seating the shank. Secure the 1\/4 inch shank in an appropriately sized collet or end mill holder to the holding system manufacturer's specified clamping torque. Verify runout with a dial indicator before beginning a cut, as excessive runout accelerates edge wear and degrades surface finish.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide, Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 2-1\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 45 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\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\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\u003eLength Type\u003c\/strong\u003e: Long\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 \/ -0.002 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2048\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: OSG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 20480100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51734611951922,"sku":"20480100","price":127.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c9953e87fbaf73b6e2ca6112e22e7dcf.jpg?v=1788763857","url":"https:\/\/voomisupply.com\/products\/osg-20480100-square-end-mill-1-4-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
