It features a 0.25-inch mill diameter with a 0.02-inch corner radius that reduces stress concentrations at the cutting edge and extends tool life in demanding applications. The 4-flute, right-hand spiral design with a 40-degree helix angle promotes efficient chip evacuation and smooth surface finishes. An AlTiN+ coating adds thermal and oxidation resistance, making this tool well-suited for high-speed dry or near-dry cutting. Licensed machinists and CNC programmers working in job shops, production environments, and toolrooms are the primary users of this tool.\u003c\/p\u003e\u003cp\u003eThis end mill is applicable in milling operations requiring a radiused corner profile on workpiece features such as pockets, slots, and shoulders. Its stub-length classification and 0.375-inch length of cut make it appropriate for short-reach applications where rigidity is a priority. The single-end, centercutting design allows for plunge entries as well as conventional and climb milling passes. It fits standard 0.25-inch straight-bore tool holders and collet chucks commonly used on vertical machining centers and CNC mills.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.02-inch corner radius reduces edge chipping and improves corner strength on milled features\u003c\/li\u003e\n\u003cli\u003eAlTiN+ coating provides high-temperature oxidation resistance for extended tool life in ferrous materials\u003c\/li\u003e\n\u003cli\u003e4-flute right-hand spiral with 40-degree helix angle for efficient chip flow and surface finish quality\u003c\/li\u003e\n\u003cli\u003eCentercutting design enables direct plunge milling without a pre-drilled entry hole\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate delivers hardness and wear resistance for demanding cuts\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard 0.25-inch collets and end mill holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement for 0.25-inch shank corner radius end mills in standard ER, TG, and straight-bore collet systems on CNC vertical machining centers and manual mills.

Ensure the spindle is fully stopped and the machine is in an e-stop or lockout state before tool changes. Seat the shank fully into the collet or holder to the recommended gauge-line depth and torque the retention nut to the tool holder manufacturer specification. Verify runout with a dial indicator before beginning production cuts.\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\u003eCorner Radius\u003c\/strong\u003e: 0.02 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 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\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN+\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000000 \/ -0.002000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: 0.00100 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: +0.0001 \/ -0.0004 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 6\/44\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 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: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 14556372\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51730520998194,"sku":"14556372","price":79.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/34bcf475ebb624e6dee0ad656a82af58.jpg?v=1788718917","url":"https:\/\/voomisupply.com\/products\/accupro-14556372-corner-radius-end-mill-0-25in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
