With best-in-class impact energy at 6.1 foot pounds, the RH540M SDS-max Rotary Hammer is the hardest hitting and fastest drilling rotary hammer in its class. Delivering 38 percent more impact energy than previous generations and up to 20 percent more than competitors, the RH540M provides maximum productivity in all day drilling and chiseling applications. A variable speed dial for both drilling and chiseling applications allows users to adjust tool settings based on the application and material they’re tackling and a selector knob makes it easy to switch between hammer drilling, chiseling only and the Varo-Lock function. The Varo-Lock mechanism allows chisels to be rotated into 12 different positions to optimize working angles. The tools’ new, robust design keeps it working hard on jobsites. The RH540 tools both feature 12 amps and weigh just 14.2 pounds, delivering 1,200 to 2,750 blows per minute. Service minder brushes on the tools also keep them running at maximum capacity, as the tools clearly indicate when preventive maintenance is required. As with all Bosch SDS-max tools, the RH540M allows users to make tool-free bit changes with automatic bit locking and offers enhanced dust protection and maximum energy transfer rate.

The attachment didn’t work real well for what it was intended but the drill worked great.

Only used a few times but so far so good. The drill bits with the sds max head are kind of pricey but the regular bits are priced fairly

I’ve used this drill for 1.5 inch holes in granite. It has worked amazingly well, and I’ve drilled about 100 holes so far, each 10 inch deep.

Was using a friends hammer drill , it took me 45 mins to 1hr to drill 1 hole 3/4 ×6″ . Bought this tool it took me less than one minute per hole to drill remaining ones.

Had to replace my 18 year old Bosch hammer with this one. SDS Max bit compatible and seems to work just fine. The old Bosch was made in Germany this new one is made in China….. so we will see if it goes the distance. Bosch hammers are known in the trade for their reliability and longevity.

If you let this tool’s weight work for you it is a very agreeable product. Adjustable handle for control/stability makes horizontal work a breeze. All in all like it so far.

I used a 1 1/4” bit to drill a hole through a 8”concrete wall. Just like drilling thru butter.

I had about 40 5/8” holes to drill in a new foundation. My old hammer drill was acting up and took almost 2 hours to drill 5 holes. Got this unit and it took 3 to 5 seconds to drill a 4” deep hole. It’s a great tool

As a concrete restoration and protection company, we need tough long lasting powertools. After reviewing many rotary hammers on the market and the versatility of eachalong with a great price, nothing has compared to the Bosch Rotary Hammers of anysize and ergonomics. By far the Best that I will continue to purchase, Thanks Bosch!

Excellent product. It’s great that HomeDepot has products available in certain markets that meet consumer needs. The available attachments will handle many projects from drilling, boring, chiseling, and digging. This is second Bosch SDS rotary hammer drill and first SDS-Max for demanding projects.

Plenty of power and not overly heavy, exactly what I needed. Breaks up concrete no problem.. used it for hours and didn’t feel it getting warm at all. Only had it for a month so I can’t speak for its longevity but i don’t see this thing crapping out, built like a tank. You can’t go wrong with this tool
