Query: VERY POOR EXECUTION

Good idea, bad execution. I have used bits like this, from many manufacturers, since their inception as a contractor. These bits took a HUGE step up when the countersinks came equipped with four wings (cutters) instead of two.This bit is manufactured in typical DeWalt fashion: looks good, works good for a couple of cuts, then it breaks. I have taken broken bits back to the local DeWalt service center only to have them tell me that I'm the only person who ever brings these back broken. B******t!!!Do yourself a favor, buy a similar product that IS NOT yellow in color. It will last much, much longer.
