It is designed for hammers over 11lbs (5 kg). SDS-Max has an 18 mm shank with three open grooves and locking segments rather than balls. SDS/SDS-Plus is a 10 mm shank with 2-4 open grooves held by the driving wedges, and two closed grooves held by locking balls. SDS uses a cylindrical shank on the bit, with indents held by the chuck. These drills, as the name suggests, use rotating chucks to drill holes in different materials. ![]() Combi drills combine some of these categories. Sub categories are rotary drills, drill drivers and hammer drills. SDS, which in German is ‘Steck – Dreh – Sitz’ (translated ‘Insert – Twist – Stay’), was developed by Bosch in 1975 for hammer drills.

Rotary hammers use a drive piston that exerts air pressure to a flying piston. While a hammer drill vibrates its way into the surface, a rotary hammer pounds away with a whole lot more force. On the other hand, corded drills offer unlimited running time, but they do require you to have an outlet nearby, and introduce power cords that can be frustrating to wrangle and add a tripping hazard to your job site. The reason rotary hammers drill so much faster than a hammer drill comes courtesy of their robust internals. While cordless drills are convenient for their portability and lack of extension cord, you are limited by their battery runtime. Higher joules usually means a heavier drill though, so keep that in mind.Ĭordless versus corded power is something else to consider. It is impossible to have a conversation about heavy-duty tools and equipment without mentioning DEWALT. The higher the joules, the more energy the drill will transfer into the workpiece, and the faster it will finish the job. The overall power of the rotary hammer drill is another factor to consider, and can be assessed by looking at their impact energy-which is measured in joules (J). Other models may have a drill-only mode that disengages the hammer mechanism, which is necessary for core drilling. This will allow you to use the drill with a chisel bit, which is essential for most demolition tasks. For example, although all our options will have a primary mode for hammer drilling, some will also have a hammer-only mode that does not rotate the bit. ![]() What to ConsiderĪlthough most rotary hammer drills look similar, there are features that make some more useful than others.
