I do have a similar rotary tool but it's not a Foredom SR. Rotary Tool
I got it for £68.00 and then received £20.00 for a review. I use it either with a pedal on the lathe or with a voltage regulator when standing at the bench.
I'm not on here so much now so didn't see it Blister.
I've had a Foredom for many years but without looking I can't remember which model it is, I got it s/h from a mate so it's an old one but an excellent bit of kit which I don't use often but much appreciate the quality when it is used.
I’ve got the foredom rotary machine, apologies I’ve not been lurking on site for a while. I believe it’s the SR I’ll check tonight when I get home. Excellent for power carving, a bit underused at the moment
I intend to service the machine before putting it to use , When it arrived the previous owner did not send the spanner needed to remove the cutter , He said he does not have it ? , I need one of these some lube for the flex shaft plus a bearing set ,brushes , should then be good to go.
