Impact drill covers three tools at the rental counter, and they are not interchangeable. A hammer drill puts holes in brick and block. A rotary hammer drives anchors into concrete all day. A demolition breaker removes concrete rather than drilling it. Day rates run from about $35 to $120 depending which one you actually need.
The bit shank tells you which class you have
A hammer drill takes round shank masonry bits and hammers lightly while it turns. A rotary hammer uses an SDS or SDS max shank, where the bit slides in a chuck and takes a real piston blow. If the counter hands you a tool and no matching shank of bits, you have the wrong pair for the job.
Match the tool to the hole, not to the wall
Small anchors in block are hammer drill work. Half inch and larger anchors in cured concrete, or a run of them, want a rotary hammer, which will finish in minutes what a hammer drill overheats trying. Rebar in the path is another step again, and calls for a bit rated to cut through it.
Bits and chisels are a separate bill
The tool rate almost never includes consumables. Bits, points, flat chisels and core barrels are hired or sold per item, and a snapped or badly worn bit is charged back. Take the exact hole diameters and depths to the counter and hire one spare of the size you will use most, because a Sunday stall is expensive.
Concrete dust is the part with a rule attached
Drilling and breaking concrete releases respirable crystalline silica, and OSHA sets out engineering controls and respiratory protection for that work in construction. Rental counters hire the dust shroud and vacuum alongside the tool. Ask for them at booking rather than sweeping up afterwards and hoping.
Questions people ask about impact drill rental
Is an impact driver the same as an impact drill?
No. An impact driver hammers rotationally to drive screws and bolts and is poor at drilling masonry. An impact or hammer drill hammers along the bit axis into brick and concrete. If the job is anchors in concrete, the tool you want is a rotary hammer.
Do I need a corded tool or will cordless do?
Cordless rotary hammers handle a handful of holes and awkward access well. For a full day of anchors, corded or a big battery platform with spare packs is the realistic hire, because charging time becomes the bottleneck long before the tool tires.
What size breaker should I rent for a slab?
A 35 pound class handles a thin patio slab and tile beds. Four inch and thicker reinforced slabs want a 60 pound machine, and footings want a 90. Oversizing costs a few dollars a day; undersizing costs the whole weekend.
