I have a full set of drill bits and cork pliers over my workbench in my basement. They do a great job, BUT they are not suitable for quick work in the garage or anywhere else. These JNB Pro wood countersinks and wood cutters are the perfect solution. These are the most common sizes I use and I don't have to pay for another full set. Countersinks cut cleanly, and when I need to hide a screw head or fill in a previous hole, dowel cutters get the job done without going down to the basement!
