It features a 13\/64 inch (0.2031 inch) cutting diameter, a 5\/8 inch length of cut, and a 1\/4 inch shank diameter for use in standard collet chucks and tool holders. The AlTiN coating provides heat resistance and extended tool life in high-temperature cutting conditions. A 40-degree helix angle and spiral flute geometry promote efficient chip evacuation and reduce cutting forces. This end mill is center-cutting, allowing plunge entry. It is intended for use by machinists and tool-and-die tradespeople in CNC and manual milling applications.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for slot milling, profiling, and contouring operations in ferrous alloys, stainless steel, and hardened materials where a high-performance coated carbide tool is required. The regular-length configuration and 2-1\/2 inch overall length make it appropriate for general-purpose work in vertical machining centers and manual knee mills. Its right-hand cut and right-hand flute configuration are standard for conventional and climb milling.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e13\/64 inch (0.2031 inch) cutting diameter with mill diameter tolerance of +0.000 \/ -0.002 inches\u003c\/li\u003e\n\u003cli\u003eAlTiN finish for elevated heat resistance and longer tool life in demanding cuts\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle with spiral flute geometry for aggressive chip evacuation\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design allows direct plunge entry without pre-drilling\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003e3-flute configuration balances chip clearance and surface finish\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 1\/4 inch shank square end mill compatible with collet chucks, ER collet systems, and end mill holders accepting 1\/4 inch straight shanks on CNC machining centers and manual mills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following standard tooling practices. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before inserting the end mill. Secure the shank to the full recommended engagement depth in the collet or holder and verify runout before cutting. Follow machine manufacturer torque specifications for collet nuts and tool holder retention hardware.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 13\/64 inch (0.2031 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 5\/8 inch (0.6250 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/4 inch (0.2500 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\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\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 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\u003eCentercutting\u003c\/strong\u003e: Yes\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\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0004 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 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: 12181940\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51730461524274,"sku":"12181940","price":42.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/53685c8d57eef538288909d36df4e7d6.jpg?v=1788717864","url":"https:\/\/voomisupply.com\/products\/accupro-12181940-square-end-mill-13-64-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
