AXrescuer Posted March 15, 2011 Share Posted March 15, 2011 I'm looking to get a new air tool to help sort the bodywork on my other Astra.So the question is, for general cutting out of rot and new bits of sheet, which of the above would be best? Ta in advance! Link to comment Share on other sites More sharing options...

cobblers Posted March 15, 2011 Share Posted March 15, 2011 For sheets of flat new steel a nibbler is OK, but they are no good to use on the vehicle at all. For cutting out rot there is really no substitute to an angle grinder with a proper (1mm) slitting disk in. I've tried air grinders, air shears and air hacksaws and they are all slow going in comparison. The air hacksaw was by far the best of the lot, and they do have other uses too. I'd still reach for the grinder in 99% of cases. Link to comment Share on other sites More sharing options...
Mr_Bo11ox Posted March 15, 2011 Share Posted March 15, 2011 My favoirite body-chopping tool is the angle grinder with those supa fine 1mm discs in, those things are class. In fact I think I only use that and some tin snips for all chopping duties. I've got one of those 'Monodex' hand nibblaz but i never use it!!! So i supose out the two options i'd go for the shears.

pogweasel Posted March 15, 2011 Share Posted March 15, 2011 Those fine discs are GR9, even a ham-fisted idiot like me can make a decent-ish job of cutting with then without removing unexpected bits of both metalwork and fingers/arms/legs/eyes etc. Link to comment Share on other sites More sharing options...
AXrescuer Posted March 15, 2011 Author Share Posted March 15, 2011 Cheers, I'll go with the shears I think. Me and grinders don't get on when cutting, had three 1mm discs fly aparton me, so no desire to experience that again! Link to comment Share on other sites More sharing options...

Grinders are by far the kings of cutting metal, get some goggles or a face shield and thick gloves on and you are pretty much indestructible as far as 1mm disks are concerned, unless you really try to cut your hand off. They are less fragile than you think (I've probably gone through 100 of them without shattering a single one). My heavy handed mate has smashed a few but because they are fibre reinforced they don't throw any real shrapnel off when you do. Link to comment Share on other sites More sharing options...

Aren't they called slitting discs or something? I've been using ridiculously thick discs without knowledge of these, which basically takes half of what you're cutting with it. edit: yes they are called that.

AXrescuer Posted March 16, 2011 Author Share Posted March 16, 2011 I must employ a bad grinder technique then cos the last cutting disc I used (Silverline) shattered and left me with a cut forehead and left ear! Link to comment Share on other sites More sharing options...

catsinthewelder Posted March 16, 2011 Share Posted March 16, 2011 Another vote for slitting discs here, get them from a welding supplies place for about 90p each. Regular tool suppliers seem to still think of them as new technology and price them accordingly. A quick word of warning though, I've let myself get into the bad habit of changing grinder discs/tools without using the supplied pin spanner. The direction of rotation means that they tighten themselves up in use. Where slitting discs are very thin they can end up overtightening themselves if you do this. I ended up breaking the locking mech on the (cheap) grinder trying to remove one that had done this On the plus side I could still get the cup brush on over the top so now spend a lot less time messing abut changing tools Link to comment Share on other sites More sharing options...
cobblers Posted March 17, 2011 Share Posted March 17, 2011 The silverline ones are toss - false economy. You can get them from screwfix at about a fiver for 10 but there is usually a bloke at a show selling good quality ones (I forget the name) in boxes of 50 for about £20, and they are really good and last about 5 times as long as a silverline one. You've got to be a bit gentle with them all, don't try and make them dig in like you would have to with a "cutting" disk that is 3mm wide. Me and a mate made this out of a stainless vivaro exhaust and only used one and a half disks: There must be 15 cuts or perhaps more? Link to comment Share on other sites More sharing options...
