Get yourself some needle tip bellows applicators go your cutting fluids and coolant.
It saves on fluids as you only put it where you want it and as a bonus there’s less mess to clean up.
At work I’ll just blast whatever I’m working on with WD-40 and if it gets all over the mill it’s no big deal.
But at home where I’m paying for the fluids and have a real possibility of tracking them into the living quarters this is a big help on both fronts.
You can get that needle right into the flutes of day a tap you’re using verses all over the surface of the part hoping it will get where it’s needed.
There’s actually two in this pic if you look, one is the micro mark cutting fluid diluted as per instructions and the other is really old WD-40 that would not come out of the can as it lost pressure.
Why it turned black is beyond me, but it still works OK.
Another thing I find invaluable is to make a caliper rack to hang your calipers on.
Gets them up and out of the way and you don’t have to search for them.
