I hate the rotary brushes of any manufacturer. Picking those little wires out of your clothes is miserable. Now I just buy the cheapest and pitch 'em at the first sign of shedding. Slowing the tool down and using minimal pressure seems to help.
I usually keep trying with progressively more expensive drill bits and bigger taps until I have sufficiently filled the hole and then throw the part away. Actually, the last time this happened I used a very small drill bit and drilled the aluminum around what is left of the tap. After drilling...
I use the 5 mil HF gloves. I've never had them deteriorate on the shelf and the correct size helps too. They are best used for light work like painting and such as they are NOT mechanic gloves. When they start to shrivel or pucker it's just time to pull on a new pair.
I learned that a small tool like a torx bit will break if you use a cheater bar on it thereby proving that the tool is ****. I have also learned that all bolts and nuts are machined to exact tolerances so if a wrench slips it proves that the tool is ****.
Tools are rusty, damage has been done already. Brass wire wheel is what I use to clean the rust off and any type of oil that is handy to wipe them down.
