This one relates to how fast angle grinders go.
A friend has bought a device from Arbortech that is a sanding pad that is a n attachment to an angle grinder - it vibrates rather than revolves. He fi nds it very effective but was looking to use it in a piece of woodwork wher e a flexible drive would give better access. He has a suitable drive which he ran off a corded drill but found it didn't do the biz -there seems to b e some centrifugal mechanism in the sander head.
This is an old drill and he reckons it only goes at 900rpm - my fairly rece nt one says 3000 which might be enough. However looking at my 4.5 inch ang le grinder it says 10,000 revs - is this really the disc speed or is this t he motor speed ?

ps I think my typo in the header of 'angel grinder' might have produced a m ore entertaining thread !!
