With a 0.012-inch cutting diameter and a 0.018-inch length of cut, this micro end mill is built for fine detail work in hard and abrasive materials. The micrograin carbide construction provides the rigidity and edge retention needed at sub-millimeter cutting diameters. Four spiral flutes with a 30-degree helix angle promote efficient chip evacuation and smooth cutting action. The bright uncoated finish makes it well suited for aluminum, copper, and other non-ferrous materials where coating buildup is a concern. Licensed machinists, toolroom operators, and CNC programmers working on precision components rely on this style of tool.\u003c\/p\u003e\u003cp\u003eThis end mill is used in CNC machining centers, vertical mills, and high-speed spindle applications where tight tolerances and small feature sizes are required. Typical applications include micro-slot milling, engraving, circuit board work, medical device components, and fine detail work in mold and die. The 1\/8-inch shank diameter allows it to fit standard collet systems without a reducer. The 1.5-inch overall length keeps runout low and maintains rigidity at the cutting edge. It is a single-end, right-hand cut, right-hand flute configuration with centercutting capability for plunge entry.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.012-inch cutting diameter with 0.018-inch length of cut for micro-detail milling\u003c\/li\u003e\n\u003cli\u003eSolid micrograin carbide construction for superior edge retention and rigidity\u003c\/li\u003e\n\u003cli\u003e4 spiral flutes with 30-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute orientation, single-end configuration\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suited for non-ferrous and abrasive material applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style tooling solution for CNC machining centers and vertical mills using standard 1\/8-inch collet or toolholder systems.

Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Secure the 1\/8-inch shank in a clean, properly sized collet or end mill holder and tighten to the toolholder manufacturer's specification. At micro diameters, runout and tool projection length have a significant effect on tool life and surface finish — minimize overhang and verify runout with a dial indicator before cutting.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.012 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.018 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 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\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (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\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\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\u003eSeries\u003c\/strong\u003e: ASQSC4-CC-30H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 12277021\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51747784589618,"sku":"12277021","price":35.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0ed9f916600e7f9ec3fca2da8f842dce.jpg?v=1788885444","url":"https:\/\/voomisupply.com\/products\/accupro-12277021-square-end-mill-0-012-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
