Hi, M/S is the measurement they use to assess vibration. HSE has a calculator, but basically less is better :) For something sensibly priced, I would highly recommend the Makita M9204 Random Orbit. Random orbits give the best level of finish, but being circular means they cannot get into corners etc. It's low rating for vibration too (I think 3.5 m/s). If you specifically need to get into corners, go for a 1/4 or 1/3 sheet sander. The Makita M9203 is about £35 on Amazon, so again well priced. The Bosch green PSS 250 AE is another option and £45 from B&Q. Ideal world, you would have both - A random orbit and a sheet/finishing sander. But the red Makita stuff is generally good quality for the price - older Makita pro designs, but made in China rather than Japan.
Hello, what is m/s , just so as I know. And is there one You would recommend . not necessarily at this price ? Thanks (y)
It's a good price, but cheap sanders can are pretty unusable due to vibration. This is 9.6m/s which is probably the highest I have seen on a sander. A have a couple Bosch sanders - the random orbit is 2.5 m/s (admittedly, it's best in class) and the tri sander like this is 5 m/s. Worth being aware of - you shouldn't be using something like this for longer than 30 mins at a time.
