I recently purchased a $135 drill bit from amazon in the interest of economizing on the recurring charges to hire a contractor to make holes in concrete. Today we cored a bunch of holes in the rowhouse party walls for our gas pipe. Essentially with the first successful hole we paid off the cost of outsourcing the job. Each subsequent hole is now free until the bit is worn out. Looks like we can preserve the bit for many jobs to come provided we avoid hitting rebar.
Bosch once again makes an exceptional product and we’ve cored our holes quickly and at our convenience.
