This is not a comment at all on the quality of the bit. I needed a 1/16 long nozzle, to patch a hole in an urgent project. Fee same day. Would have given 5 stars except the racquet in the box is the wrong size! Bosch had this fault, the box wasn't broken, the seal was intact. What how What looks like a 3/32" bit goes in a blister pack of 1/16" bits. Obviously a factory defect. I did not order this item as I believe there was a full batch. Dan! I hope that the 12" version that I just ordered in a hurry doesn't have this problem.
