I am looking at renting a handheld coring drill and 4 " coring bit to
drill some ( about 12 ) weep holes in a 8" poured retaining wall (
all easy access) . The wall is also face with brick where I want to
to drill about 3 more holes . How long would this take with a hand
held wet coring drill per hole ? .


As far at as the economics - A local concrete cutting contract wants
about $5/inch of depth for a 4 inch diameter hole - t $40/hole for the
unfaced portion, $60/hole for the brick faced portion . I can rent the
rig for about $135 /day ( includes at Hilti handheld wet drill with a
4" X 12" coring bit
w/unlimited wear included .

Can I save any substantial $ by doing the job myself and is it
simple .

Recommendations and tips are appreciated . -thanks


Did you make sure the bit is included in that price. If you have to buy a
bit, that in itself makes it worth paying the pro. They cost over $100
