Aluminum cutting cnc spiral router bit describes this Amana Tool spiral router bit built for aluminum and plastic work on CNC machines. The 1/4 inch x 2 inch x 5/8 inch sizing defines the cutting profile so paths and depths can be planned confidently for repeat jobs. Its up-cut spiral pulls chips away from the cut, helping keep the tool engaged in material rather than riding on debris. The O flute geometry is designed for aluminum cutting, shaping the chip as it exits to help maintain a consistent cutting edge engagement. A 1/4 inch shank matches common CNC collets, simplifying tool changes within existing 1/4 inch setups. As a router bit in the aluminum cutting class, it fits workflows where non-ferrous material routing is part of cabinet, fixture, or component production.
This Amana Tool spiral O flute router bit uses a 1/4 inch shank, so it fits CNC routers configured for that collet size, simplifying installation in typical small-diameter tool positions. The up-cut orientation is designed to eject chips Up through the flute, so routing programs can be oriented with that chip flow direction in mind on vertical or horizontal setups. The 5/8 inch cutting height defines the maximum cutting depth per pass for full flute engagement, guiding step-down choices to keep cutting forces within what the single flute can handle. As a plastic cutting spiral router bit that also falls in an aluminum cutting class, it fits into tool libraries where non-ferrous and plastic routing share similar mounting and spindle setups.
This Amana Tool 1/4 inch x 2 inch x 5/8 inch spiral O flute bit sits in the router bits class for aluminum cutting, so it suits CNC workflows that regularly machine aluminum components or panels. The web description also identifies it as a plastic cutting spiral router bit, which places it in jobs where plastic sheet, parts, or fixtures are routed on the same CNC. Its up-cut design is described as ejecting chips Up, aligning well with through-cuts or pocketing where chips can be lifted out of the cut zone toward dust collection. With a 1/4 inch cutting diameter, it fits operations that need smaller slots, contours, or detail routing rather than broad surfacing, supporting fixture making, panel cutouts, or part trimming in aluminum and plastic.
The O flute geometry on this Amana Tool bit is described as aluminum cutting, so its flute form is tuned to the way aluminum and similar materials chip during routing, which supports repeatable surface results when toolpaths are reused across batches. The single 1-flute design means each revolution presents one cutting edge to the work, which helps the flute stay open for chip removal in softer or gummier material. The specified up-cut motion, stated as ejecting chips Up, pulls chips along the flute and away from the cut, which helps maintain consistent engagement when running continuous toolpaths on CNC equipment. The 1/4 inch shank keeps the tool compatible with many CNC collets, letting shops standardize holders and maintain predictable runout characteristics from one bit change to the next.
The Amana Tool 51402 spiral O flute bit is described as an aluminum cutting and plastic cutting spiral router bit, so it targets non-ferrous aluminum and various plastic materials in CNC routing work.
The spiral up-cut design is stated to eject chips Up during cutting, pulling waste along the flute and away from the cutting edge, which supports smoother, more consistent tool engagement in aluminum and plastic.
The 1/4 inch shank on this spiral router bit matches common CNC collets, allowing the tool to be mounted in standard 1/4 inch tool holders used in many routing setups.
The 1/4 inch diameter, 2 inch overall length, and 5/8 inch cutting height define slot width and maximum cut depth, helping toolpaths and step-downs stay within the bit's working envelope.
The web description states that this plastic cutting spiral router bit fits most CNC machines, so it is intended for broad CNC router use where 1/4 inch shanks are supported.
The O flute geometry is described as aluminum cutting, shaping chips for these materials so the cutting edge engages predictably, supporting repeatable finish quality on aluminum and plastic parts.
The aluminum cutting cnc spiral router bit from Amana Tool, with its O flute geometry and up-cut chip ejection, serves CNC shops handling aluminum and plastic in the same workflow. The 1/4 inch shank and defined 1/4 inch x 2 inch x 5/8 inch dimensions let toolpaths be set around known limits. For routing aluminum panels, plastic fixtures, or mixed-material components on CNC equipment, this spiral router bit offers a focused option built for non-ferrous and plastic routing tasks.
