Hi.
Yes I know for sure. I made first ones with a 2 inch auger bit hand drill. As I do not have any drilling old school mortisers I done this with drilling a several holes with my 2 inch hand drill and then chisel cleaned the notch/mortice. But it took quite a lot of time so I decided to use a circular saw just for that part of joint. If I had the drilling morticer - I would do the job with this tool.
