Review on Premium Woodworking Square: Exceptional Mortising Countersink Tool for Industrial Power & Hand Tools by a Skilled Woodworker by Chef Buntiloy

They arrived in excellent condition and appear to be of good quality. They are individually wrapped and each has its own plastic box. But I was looking for how to use them, no instructions or manuals. Apparently they have to be used separately unless you have 2 clamps, one for the rotating bit and one for the stationary part of the bit. I could be wrong but my drill press only has one ring and will hold the drill bit. still a good product.
