Morning chaps,im looking for recomendations for cutting disc for my Dewalt 4" angle grinder ,only used it once in a blue moon but of late i have had more jobs that require metal cutting ,
The job is a gas bottle storage cage made from 50mm galvanised angle iron that is built on site ,so when it comes ro removing the cage it has to be cut out
Is there such a disc that lasts longer than 5/6 cuts :scratch:

Extra thin cutting discs cut faster than the traditional thicker types and oddly seem to last longer with a light touch, probably because it's less effort to cut. Ebay is probably your friend for cheap bulk purchases, though at the moment I am using some from Lidl with good success.
A guard is very important with thin discs though!

1mm discs make a nice cut but don't try to put to much lateral pressure on them

Hi,

I've used my 4" B&D angle grinder a great deal over the years but it does eat discs. I've now bought a 9" angle grinder which I collect on Saturday. I've also bought a sabre saw it being a cheap Parkside which only cost me £25 brand new at Rufforth Auto Jumble; would a cheap sabre saw do the job for you and once the job is done then you have a handy tool for other jobs unlike an angle grinder which really is only a one job tool? :scratch:

Kind regards, Col.

With good blades, good technique and some coolant a recip saw is great on metal.

Bit late to the party... probably done it now :lol:

I've used a fair few brands of the 1mm discs. Even tested some for one manufacturer.

5 or 6 cuts through a bit of 50*50 RSA would be about right to be honest.
We use them all the time, for cutting all sorts of things from heavy UBs to weldmesh.

Dont force the disc, dont let it bounce and dont let it get trapped. Sideways force is a no no aswell. All these will reduce the disc life.

Brand wise, steer clear of most of the cheapy own brand ones, they are usually a false economy, and noticeably not as nice to use as the better quality ones...
Reca are one of the best compromises between speed and wear....
Klingspor/Kronenflex are also very good.
Dronco are usually fairly soft compound which means they cut fast, but also wear faster.

Some of it also depends on the grinder. As I mentioned above vibration isnt great for the discs. Generally speaking, grinders from the lower end of the market arn't as smooth running.
