With a 0.075 inch cutting diameter and a 0.225 inch length of cut, this tool handles slotting, profiling, and peripheral milling in tight-tolerance applications. The AlTiN coating improves heat resistance and tool life in high-speed dry or near-dry cutting conditions. Four flutes with a 30-degree right-hand helix promote efficient chip evacuation while delivering a fine surface finish. The micrograin carbide substrate provides the edge retention needed for consistent performance across production runs.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for CNC machining centers, vertical mills, and high-speed spindle setups found in job shops, tool rooms, and production machining environments. The extended reach configuration and 0.125 inch shank diameter make it practical for accessing features in recessed or stepped workpieces. It is a single-end centercutting design, so it can be used for plunge entry as well as lateral cutting passes. Machinists working with aluminum, stainless, alloy steels, and hardened materials will find the AlTiN coating and micrograin grade appropriate for demanding cuts.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.075 inch cutting diameter with a mill diameter tolerance of +0.0000 \/ -0.0010 inches for close-tolerance work\u003c\/li\u003e\n\u003cli\u003eAlTiN coating for elevated heat resistance and extended tool life in high-speed applications\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate for superior edge retention and rigidity\u003c\/li\u003e\n\u003cli\u003e30-degree right-hand spiral flutes promote smooth chip flow and reduce cutting forces\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry enables direct plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n\u003cli\u003eExtended reach with a 0.5 inch reach length for accessing recessed features\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use end mill for CNC and manual milling setups accepting a 0.125 inch round shank toolholder or collet.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a machinist or toolroom technician using a compatible collet, end mill holder, or shrink-fit toolholder sized to the 0.125 inch shank diameter. Verify shank runout and holder cleanliness before seating the tool to avoid premature edge wear. Confirm spindle direction is set to right-hand rotation before engaging the cut. Follow machine tool manufacturer guidelines and applicable shop safety procedures when setting cutting parameters.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.075 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.225 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 0.5 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\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 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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: Yes\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\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0000 \/ -0.0010 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0003 inches\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: 14899139\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51738312343858,"sku":"14899139","price":52.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/81e6bd4b004cdc7e54b9edb1b3735d5f.jpg?v=1788798114","url":"https:\/\/voomisupply.com\/products\/accupro-14899139-square-end-mill-0-075-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
