Rotohammer Bit Keeps Getting Stuck
Hey All,
I’m working on a seismic retrofit currently and for the hold downs I need to drill a hole in the concrete that is about 14 inches long. But due to this tiny pocket in the basement pony wall, I have to keep swapping out drillbits so that my Roto hammer actually fits - I swap every 6/12/18 inches. Only issue is that when I swap from my 12 inch bit to my 16 inch bit the longer 16 inch bit keeps getting stuck, so then I have to stop, back it out, clean the hole, etc.
Is there a pro hack here from one of you guys? Should I oversize the hole in the first two stages so that it doesn’t get stuck in the last stage? Or maybe something else? Someone’s had to have done this before, and hopefully has some wisdom to share. Lemme know. Thanks!
