Built from micrograin carbide with an AlTiN coating, it handles hard materials and elevated cutting temperatures better than uncoated or HSS alternatives. The 1\/64 inch cutting diameter, 30-degree helix, and four spiral flutes make this tool well-suited for fine detail work, micro-slot cutting, and contouring in ferrous and non-ferrous materials. The centercutting geometry allows plunge entry. Right-hand cut and right-hand flute orientation are standard for conventional CNC and manual milling setups. Licensed machinists, tool and die makers, and precision shop technicians are the primary users.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for light-duty, high-precision milling passes where dimensional accuracy is critical. Its 1\/32 inch length of cut and 1\/8 inch shank diameter make it compatible with standard collets and end mill holders found on CNC machining centers, CNC routers, and manual knee mills. It is suited for milling small features in mold cavities, PCB components, medical parts, and aerospace details where small-diameter tooling is required. The regular-length configuration keeps deflection manageable at this diameter.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/64 inch (0.0156 inch) cutting diameter for micro-scale milling operations\u003c\/li\u003e\n\u003cli\u003eAlTiN coating improves heat resistance and tool life in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide construction for rigidity and edge retention at small diameters\u003c\/li\u003e\n\u003cli\u003eFour spiral flutes with 30-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry without a pilot hole\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute — compatible with standard spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 1\/8 inch collets or end mill holders on CNC machining centers, CNC routers, and manual milling machines where small-diameter solid carbide tooling is required.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully powered down and at rest before loading or unloading the tool. Seat the 1\/8 inch shank fully in a matching collet or end mill holder and torque the retention hardware to the machine manufacturer's specification. At this diameter, minimize runout as closely as possible — even small amounts of radial runout significantly reduce tool life and dimensional accuracy.\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: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\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\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\u003eCentercutting\u003c\/strong\u003e: Yes\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\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0002 \/ -0.0008 inches\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\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\u003ePackage Weight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 12178957\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51747066446130,"sku":"12178957","price":43.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3b0505007a983118e980aa37ff05aed8.jpg?v=1788875690","url":"https:\/\/voomisupply.com\/products\/accupro-12178957-square-end-mill-1-64-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
