With a 0.027-inch cutting diameter and a 0.081-inch length of cut, this tool is built for tight-tolerance work in small-feature machining, slotting, and profiling applications. The four-flute, right-hand spiral configuration with a 30-degree helix angle promotes efficient chip evacuation and smooth surface finishes at high feed rates. Micrograin carbide construction delivers hardness and wear resistance in demanding materials. The bright, uncoated finish suits applications where coating interaction with the workpiece material is a concern.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for CNC machining centers and manual mills where small-diameter, precision cutting tools are required. The 0.125-inch shank diameter fits standard 1\/8-inch collets or tool holders commonly found in high-speed spindles and micro-machining setups. It is a single-end tool with an overall length of 1.5 inches, making it appropriate for shallow-reach applications in mold work, die machining, engraving, and fine-detail part production. Machinists and toolroom operators working with tight geometries and small workpieces will find this tool well suited to their requirements.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.027-inch cutting diameter for fine-detail and small-feature milling\u003c\/li\u003e\n\u003cli\u003eFour-flute, right-hand spiral design for improved chip flow and surface finish\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle balances cutting efficiency with tool stability\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide construction for hardness and extended tool life\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows plunge entry into the workpiece\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish suitable for non-ferrous and ferrous applications where coatings are not preferred\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers and manual mills equipped with 1\/8-inch collets or tool holders accepting a 0.125-inch shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom professional. Ensure the spindle is fully stopped and the machine is in a safe, de-energized state before changing tooling. Secure the shank to the full recommended collet engagement depth to prevent tool pullout during operation. Follow the machine manufacturer and tooling manufacturer guidelines for speeds, feeds, and depth-of-cut parameters appropriate for this diameter range.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.027 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.081 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\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\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0000 \/ -0.0010 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0003 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 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: 12276804\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51735220650290,"sku":"12276804","price":29.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f4d35bb23d2d5f9938eb2ccf4584edb3.jpg?v=1788770494","url":"https:\/\/voomisupply.com\/products\/accupro-12276804-square-end-mill-0-027-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
