Conveyor belts for basement dirt removal
Agree on the Bosch being the 'good one'. Have the spline version, can put a 1" hole thru 8" of concrete in about 20 seconds. Bought first one (based on recomendations here) for a company project to drill about 40 ea. 5/8" dia 14 inches deep into a concrete pad for rock bolts - at 11k ft at observatory on Haleaka.
