With a 0.125-inch mill diameter, a 0.25-inch length of cut, and a 1.5-inch overall length, this is a stub-length tool built for tight setups and short-reach work. The 5-flute geometry combined with a 45-degree helix angle improves chip evacuation and surface finish at higher feed rates. The AlTiN coating provides thermal resistance and extended tool life in ferrous and hard materials. Micrograin carbide substrate supports the sharp edge retention required in fine-detail cuts. This tool is installed and used by machinists and CNC operators working in job shop, aerospace, and precision manufacturing environments.\u003c\/p\u003e\u003cp\u003eThis end mill suits applications in vertical machining centers and CNC mills where a small-diameter, high-flute-count tool is needed for finishing passes, slotting, and profiling in steel, stainless, and hardened alloys. The centercutting design allows plunge entry directly into the workpiece. The right-hand cut and right-hand spiral flute configuration is standard for conventional CNC spindle rotation. The double-end design provides two usable cutting ends, extending tool utility between resharpening cycles.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5-flute spiral design supports higher feed rates and improved surface finish in finishing operations\u003c\/li\u003e\n\u003cli\u003e45-degree helix angle promotes efficient chip evacuation and reduces cutting forces\u003c\/li\u003e\n\u003cli\u003eAlTiN finish provides high-temperature resistance for dry or semi-dry cutting in ferrous materials\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate delivers edge retention in hard and abrasive workpiece materials\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge milling without a pre-drilled entry point\u003c\/li\u003e\n\u003cli\u003eDouble-end configuration yields two cutting ends per tool\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard-fitment square end mill for CNC machining centers and manual mills accepting a 0.125-inch shank diameter collet or end mill holder.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Secure the shank in a properly sized collet or end mill holder to the tool holding system torque specification per the machine manufacturer guidelines. Confirm spindle direction matches the right-hand cut orientation before engaging the workpiece. Inspect the cutting edges for chipping or wear before each use and replace if edge integrity is compromised.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 \/ -0.002 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.25 inches (1\/4 inch)\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\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0004 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches (1-1\/2 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003c\/strong\u003e: AlTiN\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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDouble End\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\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\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: 12185255\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51748084318514,"sku":"12185255","price":65.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c4ac6188c0da1c3ad658c34c1f355be5.jpg?v=1788888879","url":"https:\/\/voomisupply.com\/products\/accupro-12185255-square-end-mill-1-8-in-5-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
