With a 13\/64 inch (0.2031 inch) cutting diameter, a 4-flute spiral design, and a 40-degree helix angle, this tool delivers efficient chip evacuation and a smooth finish in ferrous and non-ferrous materials. The AlTiN coating provides heat resistance and extended tool life at elevated cutting speeds. A 1\/4 inch shank diameter and 2-1\/2 inch overall length make it compatible with standard collet and end mill holders used in CNC mills and manual knee mills alike. Micrograin carbide construction gives the tool dimensional stability and edge retention in demanding cuts.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for slot milling, peripheral milling, and plunge operations in tool rooms, production shops, and maintenance environments. Its centercutting geometry allows direct plunge entry into the workpiece without a pre-drilled hole. The right-hand cut and right-hand flute configuration is the standard orientation for conventional vertical milling setups. Regular length classification makes it a straightforward drop-in for general-purpose work where extended reach is not required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for edge retention and rigidity\u003c\/li\u003e\n\u003cli\u003eAlTiN finish for heat resistance and extended tool life at high cutting speeds\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle promotes efficient chip evacuation and reduced chatter\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge milling without pre-drilling\u003c\/li\u003e\n\u003cli\u003e4-flute spiral configuration balances material removal rate with surface finish\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute for standard CNC and manual milling setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard tooling selection for CNC and manual vertical milling machines accepting a 1\/4 inch shank end mill holder or collet.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or tooling technician. Ensure the milling machine spindle is fully stopped and locked before changing tooling. Secure the shank to the full depth recommended by the collet or holder manufacturer to minimize runout. Verify that cutting parameters such as spindle speed and feed rate are appropriate for the workpiece material and the 13\/64 inch diameter before beginning the cut.\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 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 5\/8 inch (0.6250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\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: 4\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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\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: +0.000 \/ -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\u003eLength Type\u003c\/strong\u003e: Regular\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: 12182441\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51740620259634,"sku":"12182441","price":42.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/37d4b601ae9bcdedd8a3c16032a9ce24.jpg?v=1788826257","url":"https:\/\/voomisupply.com\/products\/accupro-12182441-square-end-mill-13-64-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
