June 9th, 2015The driveway was done pretty well. But I just discovered today that the concrete crew did break a bolt in the main cleanout cover when they were trying to fit it level. Of course I am not going to let a broken bolt sit in my driveway even though the cover doesn’t really move with the broken bolt. So here comes the tool that will help me extract the broken bolt – A left hand drill bit + screw extractor. I used this Neiko 10-Piece Alloy Screw Extractor Solid Cobalt Left Hand Drill Bits Set from Amazon.ca. So the idea is you use the left hand drill bit to drill a hole into the center of the screw in reverse direction. This way you drill a hole without having the possibility of driving the screw down further / tighter. Then you use the screw extractor which goes into the hole that you drilled to grab onto the remaining metal and slowly rotate the bolt out.
