la bala Posted September 10, 2021 Report Share Posted September 10, 2021 I was given a Metabo chop saw by my son in law, virtually brand new. It came with a metal disc fitted and a box of metal cutting discs of a different make. Last weekend I tried to use it, well I just dont know whats wrong with it. I tried to cut some 50x50 box, It eventually wore its way through leaving a terrible cut with burrs. I tried the different make of discs with same outcome. I tried light, medium and heavy pressure on the handle, even the box section started to glow. Its no big deal as I have been out and bought myself an Evolution chop saw with a TCT blade, a proper chop saw. I would still be interested on your comments of what could be wrong.

I am scratching my head on this one Simon, I even went down our welding centre and showed them the discs i was using, they said the wasnt mickey mouse discs. I came away with one of their discs and got the same results. I always fit discs with the name to the outside, if they were directional they would have arrow surely.

Well its off back to the son in law tomorrow, I am well pleased with my new chop saw with toothed blade. Next question, how long do toothed blades last.
