One Source Equipment Rentals has electric rotary hammer drills for rent or sale from Bosch, Hilti, and Milwaukee. Rotary hammer drills work much faster than regular hammer drills because the hammer is piston driven rather than clutch. Chisels and points can be used in “hammer only” mode for light demolition. We have various carbide drill bits and coring bits available with spline, SDS plus®, and SDS Max® shanks. See also pneumatic rock drills for drilling and concrete breakers for larger demolition jobs.
