Bosch Rotary Hammer Drill

A regular drill looks at concrete and cries. A hammer drill politely taps. A rotary hammer punches through it like the wall owes it money. Bosch's SDS-Plus rotary hammers deliver pneumatic-style hammering action that drives masonry bits through concrete, brick, and stone in seconds. You need it exactly twice a year — mounting a TV bracket in a basement wall, anchoring a ledger board for a deck — and both times you'll be grateful you own it instead of renting one from Home Depot at $50/day.
