Who likes ultra loud air die grinders,

I wear hearing protection when using this stuff as well since I use mine mostly with cutoff wheels and rotary files. I feel no power loss on any of my tools with some cotton shoved in the exhaust ports. I use the 90° and inline harbor freight "screamers" that have the bronse air valve for the trigger and no trigger lock. I use em at work daily and average about 6-7 years out of one. When they put em on sale for $9.99 and $12.99 I grab em and throw down a 20% off coupon. Just keep em on the shelf until the old ones pop. I have one harbor freight inline I bought 25 years ago, and it still runs great. The key to longevity with the harbor freight 90° and 45° grinders longevity is to never freewheel but keep them under load so the gears stay in constant mesh.
