With a 0.02-inch cutting diameter and a 0.06-inch length of cut, this tool is built for fine detail work and tight-tolerance operations in hardened and abrasive materials. The micrograin carbide construction provides the rigidity and wear resistance needed for consistent performance at small diameters. Four flutes and a 30-degree right-hand helix promote efficient chip evacuation while maintaining a smooth, accurate cut. The bright, uncoated finish is suitable for a range of general-purpose milling tasks. Licensed machinists and CNC tooling technicians are the primary installers and operators.\u003c\/p\u003e\u003cp\u003eThis end mill is well suited for finish milling, slotting, and profiling in small-scale or precision CNC machining environments. Its 1\/8-inch shank diameter fits standard collet and end mill holder configurations used on vertical machining centers and CNC mills. The 0.02-inch diameter makes it particularly applicable for micro-milling, engraving, die work, and detailed contouring where larger tooling cannot access the feature geometry. It is centercutting, allowing plunge entry into the workpiece when the operation requires it.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.02-inch cutting diameter with plus 0.0000 \/ minus 0.0010 inch diameter tolerance for tight dimensional accuracy\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide construction for improved hardness and wear resistance compared to standard carbide grades\u003c\/li\u003e\n\u003cli\u003e4-flute spiral design with 30-degree right-hand helix for efficient chip evacuation and smooth surface finish\u003c\/li\u003e\n\u003cli\u003eCentercutting capability allows direct plunge cuts without pre-drilling\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for general-purpose milling across a variety of workpiece materials\u003c\/li\u003e\n\u003cli\u003eSingle-end, regular-length geometry for rigidity in close-tolerance applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard replacement or production end mill for CNC machining centers and manual mills equipped with 1\/8-inch collets or end mill holders.

Always power down and lock out the spindle before changing tooling. Seat the shank fully into the collet or end mill holder to the recommended engagement depth before tightening. Inspect the tool for chipping or runout before initiating a cut, as small-diameter carbide end mills are sensitive to improper seating and excessive overhang.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.02 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: plus 0.0000 \/ minus 0.0010 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.06 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: minus 0.0001 \/ minus 0.0003 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\u003eSingle or Double End\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\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\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: 12276797\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51730413519154,"sku":"12276797","price":29.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/86c414a2d06355b1126dfacb6cdbdbae.jpg?v=1788717022","url":"https:\/\/voomisupply.com\/products\/accupro-12276797-square-end-mill-0-02in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
