Review on Saipe Keyhole Diameter T Track Slotting by Bob Walters

Although this is not an expensive product, its cost leaves a lot to be desired. Unfortunately I bought the set because I needed one of the bits and thought why not get the whole set right away? Why not, the one I needed broke right at the gate the first time I used it. I had to make the next size up because of the bits and redo the screw head. Not sure if I'll be sending them back or not, but buy them if you can use them for your task, not if you really need them.
