Couple thoughts on grinders......

[RivennHewn]

I spent a few hours this morning removing the anti corrosion coating off some schedule 40 fire sprinkler pipe for an upcoming project.

I was using a 80 grit flap disc.

I started out with what is probably my 'Best' grinder, a larger, heavier, more powerful Milwaukee.

My hand got tired.

I then changed to a DeWalt, but it has a large paddle type switch that you have to hold in the On position.

My hand got tired.

I then changed to a cheap, lower end Makita.

With it's smaller diameter body and a locking switch, user fatigue became less of an issue.

I ended up finishing the bulk of the work with the cheapest grinder.

1) It's nice to have multiple options.
2) Bigger isn't always better.
3) Select the tool that best suits the task.
4) Always wear your safety glasses.

5) Always wear hearing protection.
6) Always wear a dust filter specially with the old lead paint.

I also use a face shield over my safety glasses and a pair of welding gloves.
I like the big one for chewing off the thick metal and if I have a lot of zip disc work as it cuts faster and deeper than the little ones plus it's easier to keep the cuts square on angle or tubing.

Your paddle switch dewalt does not have a lock on button? Both of mine do. It's towards the back right by the rear most air slots

That's what she said!

On a serious note I know what you mean. I have 15 different grinders. I always find myself using my small Metabo grinder I got for $25. For stripping coatings I find using a wire cup or 3m stripping disc works best.
