Two things: First: Trigger locks on hand held tools. I'm hard pressed to imagine a safe situation for them.
Second: Resist the temptation to grab the chips off the drill bit with your fingers until it has completely stopped turning. They can "Chinese finger lock" you and cut you all up.
Bonus: Don't prank the rest of the crew by rolling this across the shop floor:
There ya go, a valid application I couldn't've imagined because well, I never buff anything. But I cringe at the thought of a dropped right angle grinder, locked "on".
I'm from a family of welders and family-run welding shops.
Not all of the techniques I have seen the elders and/or employees use would make the "safe" list... but nearly all that crowd never used the trigger locks on the grinders.
Hmmm - my DeWalt ONLY runs locked on. The switch has a detent that locks it. You have to physically move the switch back off the detent to the off position. And to my embarrassment, I must say I've never even thought twice about that issue until reading your post, @Tinkerah - now I'm going to live in mortal fear of that thing!
Since I've become an old man, my eyebrows have grown bushy enough to hide it, but I had a small scar in the left one from a car falling off an old bottle jack (circa 1964). Didn't have jack stands, but I had put a Chevy 14" wheel under the crossmember. That wheel saved me from a crushed skull, I'm convinced! 😁
Amen - terrific advice @SteveNL!
Anyone who has seen the movie "Jaws" should remember the guys comparing scars. Cool scene, but comparing angle grinder scars in real life is not really all that cool! (and yes, I've got a pretty impressive one too)
