What type of air tools to purchase?

[thedog]

I use a lot of air tools here at the shop, IMO the best you can buy are cleco
they last a very long time and believe me my guys don't use them lightly
die grinders, right angle grinders, scalers or impact wrenches, cleco is the way to go.

stay away from oil less compressors. they do not last, a professional grade that allows you to change oil and maintain are best.

for painting we have used Binks here for years, I have some guns that are 25 yrs old and still work like new, maintenance is key here, after each use clean to new condition, oil , spray some oil thru gun after reassembly
