The tool is ground from micrograin solid carbide, which provides higher hardness and edge retention compared to high-speed steel. It features an AlTiN (aluminum titanium nitride) coating that improves heat resistance and tool life in dry or semi-dry cutting conditions. With a 0.25-inch cutting diameter, a 0.25-inch length of cut, and a 4-inch overall length, this end mill suits applications where reach and precision in contoured surfaces are priorities. It is installed and operated by machinists and tool-and-die professionals in CNC and manual milling environments.\u003c\/p\u003e\u003cp\u003eThis end mill is well suited for finish profiling passes, die cavities, mold work, and curved-surface interpolation in steel, stainless, cast iron, and hardened alloys. The 30-degree right-hand helix promotes efficient chip evacuation and smooth cutting action. The 0.25-inch shank diameter is compatible with standard ER and straight-bore collet systems found on vertical and horizontal machining centers. The 2-flute geometry provides adequate chip clearance for slotting and light ramping operations. This tool is sold as a single unit and is intended for professional machining applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for superior hardness and edge retention\u003c\/li\u003e\n\u003cli\u003eAlTiN coating improves thermal resistance and extends tool life in dry cutting\u003c\/li\u003e\n\u003cli\u003e30-degree right-hand helix promotes efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eBall end profile enables contour milling, profiling, and 3D surface interpolation\u003c\/li\u003e\n\u003cli\u003e2-flute design provides chip clearance for slotting and light ramping\u003c\/li\u003e\n\u003cli\u003eSingle-end configuration with right-hand cutting direction\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or standard tooling option for CNC and manual milling machines accepting a 0.25-inch straight shank via ER collet, end mill holder, or equivalent workholding.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following the machine tool manufacturer's guidelines. Ensure the spindle is fully powered down and locked out before changing tooling. Verify collet size, runout, and holder cleanliness before seating the shank. Do not exceed the manufacturer's recommended depth-of-cut or feed rate for the workpiece material and machine rigidity.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\u003eCoating\u003c\/strong\u003e: AlTiN\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\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\u003eWeight\u003c\/strong\u003e: 0.12 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 12180925\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51732211237170,"sku":"12180925","price":112.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/88f99ff9203e78a746f6673376203d62.jpg?v=1788740466","url":"https:\/\/voomisupply.com\/products\/accupro-12180925-ball-end-mill-1-4-in-2-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
