Ok, here is what I just found out. I have the Quick clamp on my Hegner so I was able to cross check the two screws from the Dewalt. The threads are the same which would allow for someone to put the Dewalt clamp screw into the Hegner instead of the Quick clamp. The tips appear to be the same but I'm not sure they would interchange. The Dewalt uses a rubber o-ring as the holding device to keep the tip in. The Quick clamp uses a plastic sleeve. I tried to put the Dewalt tip into the Quick clamp and it fits but when you try to push the o-ring into the hole, it binds. It could probably be forced but I didn't want to do that. So, I hope this is understandable. If anybody has questions, just ask me.
