Power Rotary Hammers

Select by task: light demolition and small anchors need 1–3 joules impact energy and 6–10 lb weight; concrete drilling and frequent chiseling need 3–10+ joules and higher SDS-plus or SDS-max compatibility; consider motor power (amps or watts), impact rate (bpm), chuck type, and vibration control for long jobs

SDS-plus is for bits up to about 1–1/8" and suits light to medium drilling; SDS-max accepts larger shanks for heavy-duty bits and higher impact energy needed for large holes and sustained chiseling; choose based on the drill bit sizes and job scale you expect

Prices vary by power and brand; basic light-duty models often fall in the lower hundreds, while mid- to heavy-duty professional units commonly range from the mid-hundreds to higher; the category average price is around $180, so set a budget according to intended use and features required

Look for anti-vibration systems, side handles with adjustable positions, overload protection or clutch, a trigger lock for continuous operation, and compatibility with dust extraction adapters for cleaner and safer drilling

Regularly clean vents and chuck, use correct lubrication where specified, inspect and replace worn carbon brushes or seals, avoid overheating by using correct bits and duty cycles, and store in a dry case to prevent corrosion

Yes—most rotary hammers have modes for rotation-only, hammer-only (chiseling), and hammer-plus-rotation; use masonry/concrete drill bits for drilling and dedicated chisels (flat, pointed) for demolition or shaping, matching the chuck type (SDS-plus/SDS-max)

Cordless models offer portability and are suitable for many jobs, but their continuous power and runtime depend on battery capacity; corded units typically deliver more consistent high power for prolonged heavy-duty use, so choose cordless for mobility and corded for sustained high-demand tasks
