Aluminum cutting CNC spiral router bit from Amana Tool is a 1/8 inch x 2 inch up-cut O spiral with a 1-flute design and 1/4 inch shank, which gives CNC operators a compact tool sized for fine aluminum and non-ferrous work where a quarter-inch collet is standard. The bit belongs to the router bits class and is part of Amana Tools aluminum cutting line, so it fits straight into workflows where dedicated non-ferrous geometry is preferred over general-purpose wood bits. The right hand helix with right hand cut pulls chips up and away from the cut, helping clear aluminum and similar materials from the kerf and supporting smoother passes. A maximum RPM rating of 35,000 allows high spindle speeds on many CNC routers, giving flexibility to match feed and chip load settings to material and job requirements.
The bit uses a 1/4 inch shank, so it fits routers and CNC spindles configured for a quarter-inch collet, simplifying setup where that collet size is already standard on the machine. The overall length is 2 inches, giving a compact profile that supports rigid fixturing and reduces leverage at the collet during cutting. The right hand helix and right hand cut orientation match typical clockwise spindle rotation, so chip flow and cutting direction line up with common CNC toolpath strategies. A maximum speed rating of 35,000 RPM allows this router bit to run at high spindle speeds routinely used for small-diameter tools, giving programmers flexibility to balance feed rates, chip load, and finish quality.
This Amana Tool spiral aluminum O bit is specifically designed for a variety of CNC machining applications, so it fits well into router-based workflows where non-ferrous material cutting is part of daily production. It is excellent for cutting Aluminum, Alupanel, Brass, Copper, and other non-ferrous metals, which allows one tool to handle a mix of sheet, plate, or composite panel work within that material group. The bit is also excellent for Plastic, Silver, Solid Surface, Wood and more, so shops handling mixed panels or trim pieces in both metals and non-metals can keep tooling changes down while maintaining geometry tailored to these materials. Using the highest quality sub-micrograin carbide means the cutting edge stands up under these varied materials, supporting repeat jobs across different substrates without frequent tool changes.
The special proprietary edge processing system on this bit produces a super high polished cutting edge with a unique mirror finish, so each flute engages the workpiece smoothly and supports predictable chip formation at the toolpath level. That mirror-finished edge yields clean cuts and a superior surface finish, reducing sanding, scraping, or secondary finishing time on visible edges in aluminum, plastics, and solid surface work. The same edge design gives less chance for chip re-welding in aluminum and other non-ferrous metals, which helps keep flutes clear, preserves edge definition, and supports accurate part dimensions throughout longer runs. Right hand helix and right hand cut geometry lift chips out of the cut and toward dust or chip extraction, helping maintain clear toolpaths and stable cutting forces. For optimal results and extended tool life, the manufacturer states that a mist lubricant system or air cooling should be used, which helps manage heat at the cutting edge and supports consistent cut quality over longer machining cycles.
This Amana Tool bit is excellent for cutting Aluminum, Alupanel, Brass, Copper, Non-Ferrous Metals, Plastic, Silver, Solid Surface, Wood and more, allowing one tool to handle varied CNC shop materials.
The right hand helix with right hand cut pulls chips upward from the cut zone, helping clear aluminum and non-ferrous chips from the kerf and supporting smoother CNC passes.
This spiral router bit has a 1/4 inch shank, so it mounts in routers and CNC spindles set up to hold quarter-inch shank tooling in the collet.
The bit is described as a 1/8 inch x 2 inch up-cut O spiral, which provides a 2 inch overall length while the 1/8 inch cutting size supports fine-detail work.
This router bit has a maximum RPM of 35,000, allowing high spindle speeds commonly used with small-diameter CNC tooling.
The mirror finish cutting edge yields clean cuts, reduces chip re-welding, and delivers a superior surface finish, which cuts down on secondary edge finishing work.
This Amana Tool 1/8 inch x 2 inch up-cut O aluminum cutting CNC spiral router bit pairs sub-micrograin carbide with a mirror-finished cutting edge to deliver clean cuts and longer tool life in non-ferrous and mixed-material work. The 1/4 inch shank and right hand helix, right hand cut geometry align with common CNC router setups, simplifying tool changes and programming. With a maximum speed rating of 35,000 RPM and suitability for Aluminum, Alupanel, Brass, Copper, Non-Ferrous Metals, Plastic, Silver, Solid Surface, Wood and more, it fits directly into production where one dedicated aluminum bit needs to cover a wide range of jobs.
