With astounding impact energy the RH540M SDS-Max Rotary Hammer is the hardest hitting and fastest drilling rotary hammer in its class. Delivering up to 38% more impact energy than previous generations and up to 20% 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, with an easy to use selection knob to switch between hammer drilling, chiseling only and the versatile Vario-Lock function. The RH540M's robust design keeps it working hard on jobsites and reliable service minder brushes keep it running at maximum capacity. As with all Bosch SDS-Max tools, the RH540M allows users to make tool-free bit changes with automatic bit locking, and offers enhanced features such as dust protection and maximum energy transfer rate.

Bosch RH540M-RT 12 Amp 1-9/16 in. SDS-Max Combination Rotary Hammer
I purchased the Bosch tool reconditioned, like the last 5 tools I bought from CPO the hammer drill was in like- new condition. I needed something heavy to demo some stone veneer on a set of poured concrete steps at home. When I opened the box, I thought I made a mistake and got something much bigger than needed but after using it I realized that the weight of the tool is to your advantage. With the 3" scaling chisel, I made short work of the veneer and smoothed the concrete down for a more substantial set of veneer steps and risers. Instead of renting a tool like this for my job, I'll always have it ready to go.

Thank you CPO for offering these reconditioned tools, they are a great value to us tradesmen and have never let me down.

Great tool. No way to recognize the tool being refurbished.

Bosch RH540M-RT SDS-Max Rotary Hammer gets the job done fast!
This tool saved me a considerable amount of time the very first time I used it. What would have taken about an hour with my hammer drill, only took ten minutes with the Bosch RH540M-RT Rotary Hammer. It was easy and surprisingly comfortable to use. Even my wife was impressed with how quickly it got the job done!

Great Tool,Great Price
While I have only used this particular hammer drill once since purchase,It performed flawlessly. I own three other other small hammer drills and have rented big hammer drills many times that were the same size as this 1 9/16.Bosch. This is the hoss. It is the best of them all. I have spent enough in rental fees to have paid for this one.maybe 1.5 times, especially at CPO's selling price. CPO delivered in just a few days It came in a metal case in a box with no shipping damage. The metal case is really more than I expected. I have several Bosh Tools and this one is definitely a superior tool as all the Bosh Products I own. If you need a large hammer drill I found nothing to compare in price and quality to this item from CPO Tools. The only thing lacking or missing from the shipping package was some documentation like a shipping receipt or a packing slip. I will definitely check out CPO Tools before my next purchase.

New Vs. Reconditioned

What's the difference between New and Factory-Reconditioned?

Factory-Reconditioned products have been returned to the manufacturer and are restored to like-new operating condition; they go through a rigorous testing and inspection process. Plus, they offer a significant savings vs. new.
  • Reconditioned products may have minor cosmetic blemishes or scratches that do not affect item performance.
  • Reconditioned products may not come with all of the consumables the new version comes with (bits, sanding pads/papers, cases, etc.).
  • Both come with a manufacturer warranty and are covered by our Money Back Guarantee; New is 30 days, Reconditioned is 120 days.
