So what do you think, full of hot air or plausible?

Gotta go BIG or go home Bruce ! This is mine . Last time I used it I ended up in West Virginia along with the mill .

Am I missing something , I sometimes set my coolant mister without the coolant just blowing air . Isn’t that the same thing ?

For a fixed head moving table, yeah pretty much the same thing, or if the mister is attached to the head. I would say though that this blower attached to spindle with high rpm creates a very strong down blow perfectly centered on the cutter at all times. I did attach just air to my CNC and kind of worked but because it was always positioned from one side blowing across the cut it would often not be effective. For instance a meandering slot.

You've got the water cooled one in the photo, it can be difficult to keep your wiring dry.

great idea.. I like it.. for 3/8 and 1/2 I would be good with just the 2 x 4 packs.

Interesting.
I have seen chip-clearing fans, but never one mounted directly on the tool.

The RedLine chip-clearing turbo fan blows away all of your milling debris.

I'd wonder how well the fan would hold up where it envelopes the endmill. I think that would fail after some number of cycles, depending on how quickly your spindle spins up to speed.

If I was going to try this, especially if I were 3d printing it, I'd go with a toroidal propeller.

Here's what the one that comes with the Nomad3 looks like:


It just clips onto the ER collet nut. Works great especially for preventing re-cutting of chips. Granted, part of the deal for this one is the spindle speed and small size of the machine.

One concern, is that if the air flow is symmetrical, how can it blow the chips away. Would not there be just as much down force of air keeping the chips in place as trying to move them ? I guess it must work if there are multiple people selling these. Looks to me more like a solution in search of a problem.
