I have a 34-124 square cut drill with rounded edges and actually 4 blades which does a great job if you just round but aren't great for beading. operations. As mentioned in previous comments, the Quadra 34-124 round die cannot do the job of edge trimming in its purest form. Freud's website for the 34-124 milling head "For beadwork, equip bits with Freud's 62-102 bearing and 62-311 step wheel." 62-311 step wheel has a 3/16 inch ID. which obviously doesn't fit the 34-124 1/4" pin so the rounded 34-124 quadra cut bit can't do the beading work. I emailed Freud pointing out that the information on their website is incorrect I will update my comment if I hear anything from them.
