If an air blast is useful for that sort of thing, what can I do to

I would think using the ail to blow a mist would be a lot more
efficient. But understand that mist might not be good thing with
carbide.

Maybe use a hypodermic needle to use less air but direct the air
better. Dan

Well, something along those lines, but I think that would not be nearly
enough air to be useful. Even the nozzle from an irrigating syringe
might be a little small.

Other nozzle possibilities include mig welding tips, plasma cutter
nozzles, and 3D printer extruder nozzles. The latter come in a
nice range of sizes. For example, an Amazon $9.99 set of 28 has
2x0.2mm, 2x0.25mm, 2x0.3mm, 2x0.35mm, 10x0.4mm, 2x0.5mm, 2x0.6 mm,
2x0.8mm, 2x1.0 mm. A $3.22 ebay set (19pcs MK8 Extruder Nozzle)
has 2x0.2mm, 2x0.3mm, 7x0.4mm, 2x0.5mm, 2x0.6 mm, 2x0.8mm, 2x1.0 mm.
Those sets are all in brass. Hardened steel and ruby tip 3D nozzles
also are available, costing about 10 times as much.

Regarding your air dryers, does the air blast need to be dry? If
not you could plumb its air out beforehand, presumably lessening
the dryer load.
