I have to agree about hit or miss.
My list of good includes:
-#2 Morse taper drill chick-have several for my lathes
-HSS turning tools-NOT the "tool steel" one-great for learning to sharpen turning tools
-right angle drill-still trying to kill my first one-keyed chuck
-diamond tip grinding burrs-do the job
-ear muffs for noise protection-have them by every machine
-brad nailers-they work
-various gloves
-Goodyear air hose-as has already been mentioned
-air hose reel-at least 6 years old-holds above hose
-chip brushes, acid brushes, artist brushes, various disposables
-welding magnets
-star (Torx) socket bits-when you need them you need them
-Evaporust
-Slime
You get the point. I have also had some junk too, but not much. I've had a few things that I got for a single use and considered disposable but still have them. I watch for sales and coupons. And I like the free flashlights too-they come with batteries.
