It features a 0.5 inch cutting diameter, a 0.625 inch length of cut, and a 2.5 inch overall length with a 0.5 inch shank diameter. The four-flute geometry with a 30-degree helix angle and AlTiN coating supports aggressive material removal while maintaining tool life in ferrous and hardened materials. This is a centercutting, right-hand cut, right-hand flute configuration in a stub length profile. It is sold and installed by machinists and CNC operators in job shop and production environments.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for slotting, profiling, and contouring operations on machining centers and manual mills. The stub length format provides added rigidity and reduced deflection, making it appropriate for applications where tool overhang must be minimized. The AlTiN finish improves performance in dry or high-speed cutting conditions, particularly on alloy steels, stainless steels, and cast iron. It is a single-end tool with coarse pitch flute spacing.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eAlTiN coating for extended tool life in high-temperature cutting conditions\u003c\/li\u003e\n\u003cli\u003e4-flute, coarse pitch design for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle balances cutting force and surface finish\u003c\/li\u003e\n\u003cli\u003eCentercutting capability allows plunge entry into workpiece\u003c\/li\u003e\n\u003cli\u003eStub length profile minimizes deflection in tight-clearance setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard shank square end mill compatible with 0.5 inch collets, end mill holders, and milling chucks used on vertical and horizontal machining centers or manual knee mills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and the tool holder is clean and free of chips before seating the shank. Verify runout with a dial indicator after tightening to confirm proper seating in the holder. Follow the machine tool manufacturer guidelines for speeds and feeds based on workpiece material and depth of cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 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 Pitch\u003c\/strong\u003e: Coarse\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\u003eEnd Type\u003c\/strong\u003e: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: 12179539\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51728519233842,"sku":"12179539","price":124.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/06dec51a7a9a22eb1704e4a197b16784.jpg?v=1788692604","url":"https:\/\/voomisupply.com\/products\/accupro-12179539-square-end-mill-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
