WOOD Magazine rated Kreg as the best pocket hole jig in every price category. The CMT Summerfield unit rated high in every category except clamping where it was rated as below average.
From the Kreg web site.
Do I need to drill a pilot hole into the second workpiece?
No. The self-tapping tip of the pocket hole screw accomplishes this task for you. Even in very hard woods like hickory and maple no pre-drilling is required which saves an immense amount of assembly time.
THe Kreg pocket hole jig was invented by Craig Sommerfeld brother to Mark Sommerfeld
