Angle grinder advice.

**The Pastor** · 12th February 2009, 19:40

I have a small (100 dia or something) but i need a bigger one.

whats a good decent size to get? Im doing a bit of sub frame cutting and grinding and my 100 or something just isn't big enough.

Having a look on tm, the biggest i can find is 230? doesn't sound very big to me.

Has to be powerful too. Hate underpowered tools

at unitec in the fab lab, we had a massive monster that was just the business.

Don't have a lot of $$ either so looking at 2nd hand.

Depends.

Really.

A good 125mm is a good compromise, though, small enough to one-hand if nescessary but big enough to do some serious damage when needed.

Hitachi, Makita or Bosch. In that order.

Edit: And that 230mm job is for dealing with heavy steel sections, too bloody clumsy for light fabrication type work.

230mm is the largest dia. Usually only used for structural steelwork and railway track repairs etc.

Metabo, Bosch blue range, Makita made in Japan, Hitachi made in Japan. In that order.

Check out the thin cutting wheels too. 125 x 0.8mm is like a hot knife compared to the standard 2.5mm thickness.

125mm is a good size and the disks are reasonably priced too.
Go hunt out a bargain at the likes of cash confiscators or search trade me.
If you cant afford a good second hand brand one then get a shitty cheapy from a hardware warehouse and when it craps itself you get a new one every 12 months

perfect plan huh

We built and fabricated a go kart frame with a 125mm makita grinder, using it for everything like cutting and grinding. It did a few dozen cuts through 40x40mm square steel thats 3mm thick. Those thin blades are truly amazing and with those quick blade changing nuts its a breeze. anything bigger would be too clumsy.

Buunings do a GMC brand 230mm grinder for those times when serious grunt is called for. Only $90. Yeah its cheap and a Makita will last ten times longer but for occasional work it's quite adequate. I've used mine for cutting bricks and concrete (with a diamond wheel) - worke great

Be pointless telling him to get a little wee one, if a job's worth doing it's worth doing right.

Ah, what it is to have contacts. But are you not worried that the Armoury Sergeant will do a stocktake ?

you'd be surprised what 3 bottles of rum and a few sirloins will do...

In this wonderful world power tools have become throw-away items

. Go to Bunnings and purchase the biggest baddest mother you can afford and thrash it for the full duration of it's 'home user' warranty (12 months).

I have a $15 hammer drill that will not die from there!

I actually know a Sergeant Armourer. But NZ forces tend to be much fussier about such things. I mean, when you only have one hand grenade and have to share it round, it would be noticed very quickly if it went missing.
