With a 0.054-inch cutting diameter and a 0.162-inch length of cut, this tool is built for small-feature work requiring tight tolerances and consistent chip evacuation. The micrograin carbide construction delivers hardness and wear resistance suited for ferrous and non-ferrous materials. A 30-degree helix angle promotes smooth cutting action and reduces deflection at this diameter. The bright, uncoated finish makes it well suited for non-ferrous metals, plastics, and other materials where coating adhesion is not required. Machinists and CNC operators handling fine-detail work will find this tool a reliable fit for high-precision applications.\u003c\/p\u003e\u003cp\u003eThis end mill is used in CNC machining centers, knee mills, and toolroom setups where small-diameter, tight-tolerance cuts are required. It is a single-end tool with right-hand cutting and right-hand flute direction, standard for most vertical milling setups. The 1\/8-inch shank diameter allows it to seat in standard collets and end mill holders commonly found in toolroom and production environments. The 1.5-inch overall length keeps the tool rigid, helping minimize runout in delicate profiling and slotting operations. This is a trade tool for skilled machinists and CNC programmers working in job shops, aerospace, medical device, or general precision manufacturing.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.054-inch cutting diameter with mill diameter tolerance of +0.0000 \/ -0.0010 inches for precise fitment\u003c\/li\u003e\n\u003cli\u003e4 spiral flutes with 30-degree helix angle for efficient chip evacuation and smooth cut finish\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide construction for hardness and extended tool life\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows plunge entry directly into workpiece material\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suited for non-ferrous metals, plastics, and composites\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction, compatible with standard CNC and manual mill setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 1\/8-inch collets and end mill holders on CNC machining centers and manual vertical mills.

Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the 1\/8-inch shank fully into the collet or holder and torque the retention hardware according to the toolholder manufacturer specifications. Inspect the tool for runout with a dial indicator before beginning a cut, particularly given the small diameter, which amplifies the effects of runout on tool life and part accuracy.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.054 inches\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\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.162 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut Range\u003c\/strong\u003e: 0.100 to 0.200 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 (1\/8 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\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 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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\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\u003eVariable Index\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\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: 12276831\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51748679811378,"sku":"12276831","price":26.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c049f4815dc5287329bafa5e20521864_de25d889-2e39-49c4-abe0-c4546af51f1b.jpg?v=1788896583","url":"https:\/\/voomisupply.com\/products\/accupro-12276831-square-end-mill-0-054-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
