Angle grinder advice.

[Ixion]

Bugger! I got swindled. I paid $19. The bastards saw me coming.

EDIT: That was for a hammer drill, not a hand grenade. I don't know why all this stuff about power tools has gotten into a thread about hand grenades

[gatch]

get a 4 1/2 inch (115mm) metabo or bosch, some 1mm cut wheels, piece of cake, if you stall one you are trying way too hard



OR if you want to cut your bike clean in half and probably lose some limbs at the same time, then get a 9inch take the guard off and put a 12inch cutting disc on..

[Ixion]

Bosch make hand grenades?

[TLDV8]

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.

If you can not do simple jobs like that with the 4 inch grinder you have,a bigger unit will not improve things.
Get some decent abrasives as recommended and get on with it.
If you want to waste money buy a 5 inch unit.
As far as 9 inch grinders you can use them on light materials but you need the appropriate skills and stamina,i have seen plenty of hero's scare or injure themselves over the years,they are not for bunnies.

The bottom line is until you can handle a small (The smallest) grinder it is pointless getting something bigger.

That pretty much exactly what I was thinking...I'm working with Metal every day I'm working these days [metal buildings]...and I have a 230mm grinder,125mm grinder and a 100mm grinder... the 100mm grinder is used 95% of the time...the 230mm hasn't been used in months. 100mm grinder will cut next to anything..its light...easy to handle...mint...the 230mm grinder I have weight a heap...and not to mention as soon as you start the thing the torque rise being instant on a elec motor twists the thing in your hands!! Use your 100mm grinder...just learn to use it properly.

Mine cost $16.50 - but I'm still pretty happy with it after 3 years.

still in the box is it?

[The Pastor]

yeah but the frame has all this welded on shit where its cutting and i need to go deeper.

also it doesnt seem to be cutting one type of metal very well - do i need a better cutting disc? (or is it a weak grinder?), it cuts the other type of metal on my subframe really easily, just needs to cut deeper.

another reason for not perseving with this little grinder is that it has no shield and the blade is about 1cm from my knuckle.....

[The Pastor]

oh and i have a 105 dia blade on my grinder.

[vifferman]

I've never regretted buying decent tools, but I have regretted buying cheap ones.
Oh - and that expensive, well made but badly designed chain clamp universal filter tool. I bought it to be able to undo different sized filters on three cars and the bike, and it has worked only once. Every other time I've had to resort to "other methods" (such as punching a screwdriver through the filter).

I agree with what TLDV8 said - a bigger grinder's not necessarily going to be better for doing the job: it will be much more awkward (and tiring) to handle due to the torque and the gyroscopic action of the large blade spinning around. Buy a decent small one if your existing one's fookt, buy the right blade(s) for it, and use it as intended.

[The Pastor]

i dont think you understand. the 105 wont cut deep enough.

[vifferman]

I don't have to understand. You know what your needs are - go out and buy something suitable.
Just a thought - would one of those sabre saws work, or are they too wimpy? You'd still need the grinder to tidy things up though.

[The Pastor]

actually one of those might be better in terms of access to the area i need to cut, but they seem way more expensive.

I understand most of that but.....what's the cake for?

[pete376403]

The GMC from Bunnings has a soft start - no torque kickbaack when it starts up. The front handle also swivels through 90 degrees.

I agree with buying quality tools - I have (i guess) $1000s of good brqnd stuff in my toolbox, but sometimes a cheap tool CAN do the job

[AllanB]

The disk wear down pretty quickly - does it need replacing?

or

Crack out the hacksaw and build up those arms young man.
Use the grinder to tidy it up.

GRINDING - such a great word - I love it.
