With a 1\/64 inch (0.0156 inch) cutting diameter and a 1\/32 inch length of cut, this tool is built for micro-machining work where accuracy and edge integrity are critical. The micrograin carbide substrate supports the TiCN coating, delivering improved wear resistance and surface finish on a wide range of workpiece materials. A 30-degree helix angle with spiral fluting promotes efficient chip evacuation and reduces cutting forces. Centercutting geometry allows plunge entry, adding versatility in milling routines. Installed by machinists and tool-and-die professionals, this end mill is suited for CNC machining centers and manual milling operations requiring fine detail work.\u003c\/p\u003e\u003cp\u003eThis end mill is designed for applications involving fine-feature milling, engraving, and slot cutting where a very small cutting diameter is required. The 1\/8 inch shank diameter allows it to seat in standard collets and tool holders commonly found in CNC machining centers, engraving machines, and precision milling setups. Right-hand cut and right-hand flute configuration make it compatible with standard spindle rotation. The regular-length profile and 1-1\/2 inch overall length keep deflection minimal at this diameter, supporting repeatable cuts in ferrous and non-ferrous materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide micrograin construction for rigidity and edge retention at micro diameters\u003c\/li\u003e\n\u003cli\u003eTiCN finish increases surface hardness and reduces friction during cutting\u003c\/li\u003e\n\u003cli\u003e30-degree helix spiral flute promotes chip flow and reduces heat buildup\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge milling without a pre-drilled entry point\u003c\/li\u003e\n\u003cli\u003e4-flute configuration balances chip load and finish quality in fine-detail cuts\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute for use with standard CNC spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-application solid carbide square end mill for use in CNC machining centers and precision milling setups requiring a 1\/8 inch shank and 1\/64 inch cutting diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following standard tooling procedures. Seat the shank fully into the collet or tool holder and torque to the machine manufacturer's specification before operation. Verify runout with a dial indicator before engaging the workpiece, as runout is especially critical at sub-1\/8 inch diameters. Inspect the cutting edge under magnification before each use — carbide end mills at this diameter are brittle and should not be used if any chipping is visible.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/64 inch (0.0156 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1\/32 inch (0.0312 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inch (0.1250 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-1\/2 inches (1.5000 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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\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\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\u003eFinish\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0002 \/ -0.0008 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0004 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\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: 0.01 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: 12178956\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51744931414322,"sku":"12178956","price":43.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cdcef8607fc2a7fe41067076527666e1.jpg?v=1788862377","url":"https:\/\/voomisupply.com\/products\/accupro-12178956-square-end-mill-1-64-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
