Hitachi G12SR3 4.5" angle grinder 6.0 amp

[DXN1EL]

The SWITCH,,,,,,,,,,,,,,,,,,,,,,, I didn't pay much attention to the switch, I went to Lowe's thinking about getting a DeWalt, but I got the Hitachi because is GREEN so it will match my PowerARC 300

Hmm I have never found it hard to hold on to the paddle switch but I tend to hold the switch with my thumb or 1-2 fingers depending on angle. Knock on Wood, I have never dropped one either so I guess I really don't need to worry about it. I just find I like the paddle switch better. Any comparison preferences over versatility (probably not noticable?) and noise levels or anything like that those. I have used one with a switch in the same location as the Hitachi but I didn't want to lock it on so it was kind of a pain to try and work with. I tend to like knowing I have full control over the power tools after bing a teachers aid for a beginners wood working class in high school.. Those kids scare the crap out of people especially after one getting his hand in a drum sander, kick backs off the 5hp table saws and accidental router injuries.

I'd hate to be a wood working instructor in a high school for exactly the reasons you mentioned. I wouldn't want to be the one in charge of the class if someone lost a finger doing something stupid.

High school students doing something stupid? No way.

[zoama]

That hurt to watch.

OMG! ... and then they played it back in slow-mo .... ! I stopped it as soon as the slow-mo version started. I guess there is a reason I'm not a surgeon.

[DaveO]

the one in charge of the class

Pretty sure those kids were unsupervised that day, unless the instructor was the camera man. What was the game, "I'm stronger than a lathe"? The bolt or whatever starts to bend just as the kid loses it.

DaveO, been a rough week for me, so thanks.

I'm not laughing, but "unless the instructor was the camera man" cracked me up for some reason. But in real life he probably could not work the camera .

That makes the belt sander races we had look absolutely tame in comparison.

[Glen]

That video is crazy.

Looks like they're currently out of stock on this grinder. I guess I'll have to wait to get one. While they may not be the greatest, I've been happy with my hitachi M12VC router and I also have an older Hitachi miter saw that's had no real problems in the 8 years that I've had it.

The video is like a smooth MMA take-down and tap-out Great title "Lathe vs Idiot" Good find Ram and I hope he was OK...

His body goes out of frame a bit when he went over but it looked like his leg twisted the "right" way when he went to the other side. Good thing because I don't think knee joints would normally bend 90 degrees both ways.

Yep. It appears that he may be alright. I'd hope he learned an important lesson from it.

I bet most of us are pretty lucky that our high school lessons didn't extract a higher price in life and limb than they did.

I am thinking about putting a smaller wheel to my G18SS. I was thinking to return it, but this thing has some serious guts and is the same color as my PowerARC 300, I found this on Amazon

What do you guy think?

Not so much the size of the wheel as the weight. While a 7" can sure remove metal in a hurry, at almost 10 pounds, it's pretty much a two handed operation. The 4.5" weigh less than half that so one handed use is totally possible, great for things like flap wheels and such. They even have 4" models that are even lighter. Also the wheel speed increases as the size goes down, so a 4.5 wheel won't be spinning at it's ideal speed on a 7" grinder. I am totally happy with the 4.5" Hitachi linked to here. Unless you are grinding heavy structural steel like 1/2" thick or better, a 7" is overkill. I do like them for large cup brushes for smoothing off large surfaces. The extra weight keeps them more stable and the extended handle is nice.

I've got a 7" HF that I use with 24 grit flap disks... that thing really takes off the metal.

I run 7" wheels on my 9" and run 4" flaps on my 4.5" (cheaper) and I've not had a problem. Just make sure you check the max RPMs of the disk and the tool and you should be fine. All (6 now) grinders I have, have protectors on them. I have never had one come apart, but I know two people that have (both hurt pretty badly as well).

Sure this will strike up some stories.

My only concern I have is if I replace my 7" wheel with a 4 1/2" can the guard still perform it's job?

Maybe not quite as good as a smaller guard, but since 7" wheels are routinely used until worn down to 4.5" or smaller, it will still cover the edge of the wheel. I can see it being in the way a lot, too. You might compare the amount of wheel depression between 4.5" and 7" to see if the 7" guard is going to obstruct things too much. I'm not sure you can swap guards, you will have to measure the place where the guard attaches and see.
