nutool or something., made in Doncaster I think... but someones stuck a new 240v motor on the back. I needed to drill 30 really accurate holes in a banister - at the time I only had a plug in SDS drill so the argument was that buying that pillar drill for £75 or whatever was worth it as it would still be worth that much when I didn't need it. It's nice though! Putting it in the car was fun, we put the stand in first so it was just behind the drivers seat - hadn't considered the fact that that left most the weight hanging off behind the rear axle ... a very odd drive accross Bradford ensued.
