With a 0.03 inch cutting diameter and a 4-flute, right-hand spiral geometry at a 30-degree helix angle, this tool delivers clean, accurate cuts in tight-tolerance applications. The bright, uncoated finish makes it well-suited for use in materials where coated tools may cause adhesion issues. It is a single-end, centercutting design, meaning it can plunge as well as profile. Machinists and tool-and-die professionals specify this tool for micro-milling, engraving, and detail work on CNC machining centers and manual mills.\u003c\/p\u003e\u003cp\u003eThis end mill is a regular-length tool with a 3\/32 inch length of cut and a 1-1\/2 inch overall length. The 1\/8 inch shank diameter fits standard collet and end mill holders used on benchtop and production CNC platforms. Its micrograin carbide grade supports high RPM operation and holds an edge longer than conventional carbide in fine-detail cutting scenarios. Typical applications include slotting, profiling, and plunge milling in aluminum, brass, mild steel, and plastics where fine feature resolution is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.03 inch cutting diameter with mill diameter tolerance of +0.0000 \/ -0.0010 inches\u003c\/li\u003e\n\u003cli\u003e4-flute, right-hand cut and right-hand flute spiral geometry\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle for balanced chip evacuation and surface finish\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows plunge and ramp entry\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide construction for extended edge life at high RPM\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish — suitable for non-ferrous metals and plastics without coating adhesion concerns\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, manual knee mills, and high-speed spindles requiring a regular-length, square-profile micro end mill.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following the machine manufacturer's runout and torque specifications for the collet system in use. Ensure the spindle is fully powered down and at rest before changing tooling. Verify collet size matches the 1\/8 inch shank diameter before seating the tool. Inspect the cutting edges under magnification prior to use, as micro-diameter carbide tools are susceptible to chipping during handling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.03 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/32 inches (0.09 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-1\/2 inches (1.5 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inches (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\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\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\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle\/Double End\u003c\/strong\u003e: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: 12276807\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51731890536754,"sku":"12276807","price":27.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1109602bf56a971c54d2c3dc1f2a2e4c.jpg?v=1788736124","url":"https:\/\/voomisupply.com\/products\/accupro-12276807-square-end-mill-0-03in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
