I have a 14.4V drill bit. Will it manage this job?
About the plywood, should I attach the dartboard to the plywood, or just cut out an opening in the plywood through which the board would go directly into concrete?
My Makita 14.4v cordless did the job no problem. I probably had a 5/16" as well, I was just guessing.
It would be a great deal easier just to mount a small sheet (don't need the full 4x8) to the wall and mount the dart board to that. Home Depot and most lumberyards usually have plywood cut-offs that you can pick up for a few dollars. Stay away from MDF, it is so hard that a dart would likely bounce off more often than not.
While you're at it, you could wander over to the paint section and buy a pint of "mistint" exterior latex in an acceptable color for a few dollars to paint the plywood before you hang it.
I bet you could do the whole job this way for under $10 including the tapcons, the plywood and the paint. One other thing to consider is to buy twice as many fasteners as you need. The masonry bit that comes with the fasteners is barely good for 4 holes drilled in concrete. You might need 2 bits to get the job done, and the tapcon kit is a very inexpensive way to buy single masonry bits.
