Hi, all,
I am an electrical engineer, but I have a Mech. E. question.
I am helping a friend with a project that involves drilling 3/8-in. diameter (and deep) holes in concrete. I am aware of the bits on the market (carbide, diamond ; percussion, non-percussion), but I am not sure what would be optimal given the paramters of the application.
If you know concrete drilling and drill bits, can you please send me an email? I will send you the details, tell you what we are currently doing, and you can tell me if we are crazy or not.
Thanks,
Spencer
