Hammer drills are necessary for drilling into concrete and also handy with chipping bits for demolition needs. Availability includes a large SDS Max and multiple SDS plus sizes. All rentals will include one bit and many options are available.
The largest drill ($50/ day) is the best choice for large, deep holes especially if rebar may be an issue or for heavier demolition needs.
Medium sized ($25/ day) is best for up to 1" holes, for drilling many medium sized holes, or for light demolition needs.
The smaller options ($20/ day) are best suited for running Tapcon or 1/4" hammer in type fasteners or just a few medium sized anchors.
