Pegas Blade Chuck Head Set Dewalt/Delta

I purchased a new Dewalt 788 and right out of the box, the saw blades would not hold any time I tightened them. Took them out, and they looked to have a little bevel in the tip, just enough to slide out when tightened. I purchased the Pegas set after watching videos of folks using it. What an upgrade! The blade holders are a little larger, and the inserts are longer built better; and as a best note, the tips of the saw blade screw were completely flat across the tip. This was a huge upgrade for me and probably should be standard. I appreciate Pegas making something for another brand.
