I have several and they last well. These hole cutters look sturdy but I have had problems with them. When cutting into plastics, the hole that is removed melts itself to the spring on these, removing it without stretching or losing the spring is not 100% successfull. Also I have drilled into metal at a steady speed and had the teeth break on these. At least I can use the spring off the broken ones to replace the lost ones. It hasn't put me off S&R at all, they are great value well made tools.
