Built with four spiral flutes and a 0.0450-inch corner radius, it produces smooth, radiused edges while maintaining tight tolerances on ferrous and non-ferrous workpieces. The AlTiN+ coating improves heat resistance and tool life in high-speed and dry-cutting environments. At 1\/4 inch in diameter with a 3\/8-inch length of cut, this end mill is suited for detail work, slot milling, and profiling passes where a small-diameter, rigid tool is required. Installation and use are handled by CNC machinists and tool-and-die professionals.\u003c\/p\u003e\n\u003cp\u003eThis end mill is used in vertical and horizontal machining centers as well as manual milling machines where a 1\/4-inch shank toolholder is available. Wait — the shank diameter on this tool is 1 inch, while the cutting diameter is 1\/4 inch, making it a reduced-neck or stub-reach configuration appropriate for setups requiring added rigidity at the spindle interface. The 2-inch overall length keeps the tool compact and minimizes deflection. It is a single-end, centercutting design, allowing plunge cuts and ramp entries without a pre-drilled pilot hole. Typical applications include die and mold work, fixture machining, and contour milling in steel, stainless, cast iron, and high-temp alloys.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard materials\u003c\/li\u003e\n  \u003cli\u003eAlTiN+ coating enhances heat resistance and extends tool life in dry or high-speed cutting\u003c\/li\u003e\n  \u003cli\u003e0.0450-inch corner radius reduces stress concentration and improves surface finish at part edges\u003c\/li\u003e\n  \u003cli\u003eFour spiral flutes provide efficient chip evacuation and a smooth cutting action\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge and ramp entry without a starter hole\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction compatible with standard CNC and manual mill spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in milling machines and machining centers accepting a 1-inch shank diameter toolholder.

Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the 1-inch shank fully into the collet or toolholder and torque the retention mechanism per the toolholder manufacturer's specification. Verify runout with a dial indicator before beginning a cut, and confirm cutting direction matches the right-hand spindle rotation of the machine.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.2500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0450 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.3750 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1.0000 inches\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: Spiral\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: AlTiN+\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: ACCUPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 14788520\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51732381008178,"sku":"14788520","price":44.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4b1c2f1100335af9d5e430b9d35bab06.jpg?v=1788742262","url":"https:\/\/voomisupply.com\/products\/accupro-14788520-corner-radius-end-mill-1-4-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
