3.0 joules of impact force, which means it'll chew through concrete faster than most drills in this class, and we've seen it handle rebar hits without stalling out completely. It's basically the sweet spot for renovation crews who need something that doesn't quit halfway through a pour.

Power Action RH850 Rotary Hammer Drill

26mm is the max in concrete, but most buyers go with the 18mm bit for everyday work—the variable speed from 0 to 1100 rpm gives you control when you're near edges or old brick. The three modes (rotation, hammer, or both) let you switch form drilling to chiseling without swapping tools, which saves time on demolition jobs.

RH850 Hammer Drill Functions

What it does is keep the vibration manageable—the handle's rubberized and the grip shape fits a gloved hand well, something you'll notice after a few hours on a wall. We usually have stock, but confirm lead time if you need more than 50 units or so, as the color box packaing takes about 20 days to restock.

Not great for precision work in tile or thin masonry—the impact force is too aggressive, and you'll crack stuff if you're not careful. The 850W motor's fine for continuous use, but don't expect it to run all day without a break; the thermal cutoff kicks in after about 45 minutes of heavy drilling.

RH850 Drilling Capacity

Also, chuck setup is standdard SDS-plus, so you'll need to check your bits before ordering—we've had guys buy it thinking it takes standard round shanks, and it doesn't. Teh dimnesions (57×46×33cm) are for the whole box, so factor that into storage if you're tight on space.
