which cut off saw

[m_c]

I still use the angle grinder for small cuts, I have a very handy light little Bosch which takes 100mm discs (awaiting delivery of 100) that are 1mm thick. They don't last long, but they are cheap and cut faster than the 3mm ones. If you are jigging up for welding, you don't have to be super accurate.

Good quality discs last noticeably longer. I always used to get cheap discs, but I got given a box of good quality ones (I can't remember the name, but the box is in the shed). I'd say they last almost twice as long, unless you happen to jam them, at which point they still explode willingly
