Review on SellyOak T Slot Keyhole Router: Efficiently Craft Keyhole-Shaped Slots by Sean Maile

I don't plan to use them often and don't feel I have to spend a lot of money for super high quality. They have worked pretty well and I have a feeling they will continue to work well for casual users. I definitely recommend using a straight bit first to clean up the shaft slot. Provides a much cleaner cut and reduces keyhole bit wear.
