Default 9" Bosch grinder

Just last week, I replaced an old angle grinder with a new Bosch.
It is 15 amp, 5000 rpm, lighter than a Dewalt or Milwaukee.
It also has vibration isolation and is sweet to grind with. good balance.
But the switch sucks...you need to slide it ahead a bit to get it to operate, but slide it ahead a little more, and it is locked on Makes for a surprise if you are doing some heavy grinding and go to lay it down.
If anyone is interested, I will update later after it has had more use.

That would suck to have a dead mans switch on a 9" grinder when you didn't want it. Is there any way to disable it?

I have some time to return it if I don't like it, but except for the switch it is probably the nicest grinder I have used.
So obviously, I will have to dismantel it and see what can be done to the switch :evil:
If you look at the picture, the orange stuff is flexible, and you can put a bad disk on it and still grind in reasonable comfort.

The Bosch grinders are well built. That handle is really effective at isolating vibration.

I prefer the lock-on switch, no matter what size grinder. All four of my Metabo's have that type switch. OSHA will not approve it, so it can't be used if there are employees, but it works well in a one person shop

The lock on might be ok in a shop, but I don't want it in the field. It's good to know that it will shut off if you let go, or lose your balance
I have a real nice scar from falling with a 9" wildcat grinder

Dead man's switch is a no go for me. I had a blade disintegrate on me in a shore box this past summer. The shards bounced off of the shore box and thankfully hit my belly flat instead of on edge. I hit the ground, dropping the big bertha grinder. I don't use guards on the pipeline, and neither does anyone else that I know of.

I have the older version of that same grinder. Had it about six years now and can't seem to wear it out. It's done a lot of heavy work. Other tools come and go but that one just seems to keep on running.

That switch does need a bit of getting used to. Other grinders over here have the little lock-on button on the side of the trigger, that always seems to get broken off. Not an issue with this one.

Milwaukee tools are hard to get hold of in this country and Dewalt seem to be slowly losing their "professional" reputation, so Bosch seems to be the name to trust.

Hi,

I used to use a couple Bosch large grinders but I didn't have a lot of luck, and repair costs seemed very high.

I still have a couple small ones that work well. I have an older Sioux 9in that's an animal. I like the Milwaukee large grinders as well , but my faves are Black and Decker Sand Cats I use these every day with large wire brushes. I hang these on a trolley systems with counterbalancer and they hold up great. I think dewalt makes a similar model but I have never used one. I have about 5 of the bds now. Bought one that is like new at a garage sale the other day for 35.00..

I really like the Metabo tools but this biggest Metabo grinder that I have is 6in model. It works very well.

On a side note I guess Sioux is discontinuing its automotive line effective 10-01-06, sad they were great tools.

Some clown sold a used 9" bosch that he "found" to my boss about a year ago. Price was right and the thing looked brand new. I used it 4 times and the switch crapped out. Its been sitting on the "dead tool" shelf since then.

Default Making it a real grinder

The deadman switch had to go, so I took it apart and found the lock, pic 1
Then ground it off with a carbide burr, pic 2
Pic 3, it's a real grinder now.
