They work great
This set is well made and they really do a great job. I use these at work and they save time not having to change bits!
just another drill set. had problem enlarging hole on table saw wrench, from 1/4" to 5/16"?
Needed this to drill in a truck frame, tried using a regular bit and it was a struggle, got the step drill and it made the job tremendoulsy easier and where most sets don't go to 1 inch this set does.
