At 0.025 inches in diameter with a 0.075-inch length of cut and a 1\/8-inch shank diameter, this tool targets micro-milling applications where tight tolerances and fine feature detail are required. The AlTiN (aluminum titanium nitride) coating provides elevated heat resistance and surface hardness, extending tool life in harder workpiece materials. Micrograin carbide construction supports rigidity at small diameters where tool deflection and breakage risk are highest. This end mill is installed and operated by machinists and tool-and-die professionals working on CNC machining centers and precision manual mills.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for fine detail work in mold and die applications, medical component machining, aerospace part features, and electronics fixture fabrication. The extended reach geometry, with a 0.213-inch reach length, allows access to recessed features and stepped pockets without requiring a longer overall tool. The 1.5-inch overall length keeps the tool compact and stable in close-clearance setups. Right-hand cutting and right-hand flute direction are standard for conventional CNC spindle use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.025-inch mill diameter with a tolerance of +0.0000 \/ -0.0010 inches for precise feature sizing\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating for increased heat resistance and extended tool life in hard materials\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide construction provides rigidity and wear resistance at micro diameters\u003c\/li\u003e\n  \u003cli\u003e4 flutes with spiral flute type and 30-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows plunge entry into workpiece material\u003c\/li\u003e\n  \u003cli\u003eExtended reach at 0.213 inches enables access to recessed or stepped features\u003c\/li\u003e\n  \u003cli\u003eSingle-end configuration with right-hand cut and right-hand flute direction\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers and precision mills accepting a 1\/8-inch shank diameter collet or end mill holder.

Ensure the collet or end mill holder is clean and within tolerance for the 1\/8-inch shank before seating the tool. At this diameter, excessive runout or improper clamping force significantly increases breakage risk. Confirm spindle speed and feed rate settings are appropriate for a 0.025-inch carbide tool in the target material before initiating a cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.025 inches\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\u003eLength of Cut\u003c\/strong\u003e: 0.075 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut Range\u003c\/strong\u003e: 0.0000 to 0.1000 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\u003eShank Diameter\u003c\/strong\u003e: 0.125 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\u003eOverall Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 0.213 inches\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\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\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\u003eEnd Type\u003c\/strong\u003e: Single End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 14899852\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51732673003826,"sku":"14899852","price":50.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/503dffbf7dbb46111d5bab16feaee156.jpg?v=1788745592","url":"https:\/\/voomisupply.com\/products\/accupro-14899852-square-end-mill-0-025-in-4-flute-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
