About 8000 rpm and never run a depth of more than half the diameter..That being said I usually run a roughing of about 1/16 to 1/8 inch per pass...You can also google feed and speed rate charts...But a lot will depend on your router.

Can this be used on a CNC machine to cut aluminum sheets?

Asked by wslymsgrv May 10, 2019

Answers

It could be used in a wood cutting CNC machine for sure. I would use an endmill in my Bridgeport Mill for metal cutting. No doubt it would cut aluminum sheets, but this shape of bit wuold have a tendency to catch or snag thin sheets. I would use a different shape/style bit with a rounded nose. Also, an "up Spiral" will tend to lift the metal sheet, increasing the possibility of snagging. A piece of sheet metal caught on a rotating machine is a very dangerous thing. If you have no other choice, use clamps and heavy gloves.

An up spiral indicates the waste is pulled toward the router. If you were using the bit in a hand held router the waste would go up ward. If you were using the bit in a router table the waste would go downward toward the router.

What exactly is the purpose of this bit?

Asked by SB March 1, 2018

Answers

The 'up-spiral' or perhaps it could be called an 'out-spiral' bit, produces a smooth cut which lifts and removes debris out from the channel being cut, instead of leaving it full of shavings, with all the advantages others have mentioned. HOWEVER, such a spiral bit has the SLIGHT disadvantage of occasionally causing some break-out (chipping) of the edge of a channel because the cutting force is at an angle. For this reason, you would not use this bit (and should seek out a 'DOWN-spiral bit) if the definition of the edge of the channel is important, such as when routing a detailed pattern or letters/name. You will usually see down-spiral bits in small diameters where the need to avoid tear-out is most important. For most work, I find up-spiral bits preferable to straight bits, and worth the slight extra cost.

I'm going to go ahead and assume my bit was an outlier in terms of quality. During the bit's first use, while attempting a 1/4" lap in hickory, the bit literally snapped off. I bought this to replace a Ryobi bit, especially with all the reviews stating that there was no burning of the wood using this bit. Feel like I wasted $20.

Excellent for cutting circle out
I used this with my Ryobi fixed base router in a rudimentary circle jig. I cut a 21" hole out of a table I built for my Big Green Egg. Smooth, non-burnt edges in the finished cut on the 1x6 slats. Such a nice finish I'll be usig the circle cut out for a homemade wall clock. Very happy with this bit!

This bit has cut over 30' in cherry wood so far and has performed without burning and left a smooth finish. The bit is easy to guide and does not chatter.
