Complete mental blank....Please someone tell me what are those hole cutters called.....you drill a small pilot hole, attach cutter either side like a nut and bolt, then with spanner or socket on top rotate the cutter and you get a near perfect burr free hole. I have a distant memory of using them on trunking when I couldn't physically get a drill to it and in tight situations they saved the day. Or was this all a dream....as I can't remember the name of them and can't find my set either!
