Dominate Concrete Projects with the Industrial Power of the Bosch RH540M Combination Rotary Hammer

The Bosch RH540M is the ultimate professional workhorse, engineered for contractors who demand relentless power and jobsite versatility. Driven by a high-performance 12-Amp motor, this 1-9/16-inch SDS-max® combination hammer delivers a best-in-class 6.1 Ft.-Lbs. of impact energy. Perfectly balanced for all-day use, it provides the industrial-strength force required to blast through cured concrete and masonry with ease. Whether you are boring large-diameter holes for mechanical installations or performing heavy-duty demolition work, the RH540M eliminates the need for multiple tools by offering high-speed drilling and hard-hitting chipping in one robust package.

Built for the rigors of commercial construction, the RH540M features a dual-mode selector knob that allows you to switch instantly between rotary hammer mode and hammer-only mode for demolition tasks. Precision is managed through the innovative Vario-Lock™ system, which enables you to rotate and lock chisels into 12 different positions to achieve the perfect working angle for scaling or tile removal. Safety is a priority with the integrated integral clutch, which automatically disengages the torque transmission if the bit binds in rebar, protecting the user from dangerous kickback. Combined with the SDS-max® tool-free bit system for rapid changes, the RH540M ensures you stay productive and safe on the most demanding jobsites.

Key Features

  • Best-in-Class Impact Energy: Delivers 6.1 Ft.-Lbs. of impact energy for rapid concrete demolition and large-diameter drilling.
  • Hard-Hitting 12-Amp Motor: Provides professional-grade power for the most demanding commercial masonry applications.
  • Dual-Mode Versatility: Features two modes of operation: Rotary Hammer for drilling and Hammer-Only for chipping and scaling.
  • Vario-Lock™ Positioning: Rotates and locks chisels into 12 distinct positions to optimize the tool for any demolition angle.
  • Enhanced Operator Safety: Integral clutch disengages the motor if the bit binds, significantly reducing high-torque kickback.
  • SDS-max® Bit System: Provides tool-free bit changes and maximum impact energy transfer for industrial productivity.

Pro-Tip: To extend the life of the tool's internal hammering mechanism, always apply a small dab of grease to the shank of your SDS-max® bits before inserting them into the chuck. This reduces friction and heat buildup during long drilling sessions, ensuring that the 6.1 Ft.-Lbs. of energy is focused on the concrete rather than wearing down the tool's internal components.

Commercial grade divider suitable for many needs
Color: Beige, Size: A-132''W-6 Panel
This item will be used at a future event where we need to separate a single locker room into two large areas, without any construction. This divider is perfect for the job because the partitions can be 1 to 6 panels and it will roll into place. When the event is over, the divider will fold/roll away and the locker room will return to its original design. The unit is very heavy, which will ensure that it is sturdy and stable. All the components arrived, wrapped in plastic to prevent damage. The screen material is a woven polyester in a cream color that will occlude any visibility but it may be possible to see shadows on the opposite side. The height is about 6ft, which would require a very tall person to "peep over" the divider. I needed a quality unit for this project and the frame, screens, and mobility will meet the needs. The divider is not the same as the small decorative dividers -- it is more of a commercial grade product, yet tasteful. If you want/need a small divider as an accent piece, this is not the best choice. This item could be used in a medical office, treatment/massage room, to divide an office room into two, or block a hallway in a building.

Great option for a professional looking backdrop
Color: Black, Size: B-102''-3 Panel
I decided to try these wall dividers for my home office space since it does not have a door. I wanted to have my video calls without the rest of the room in the feed to give it a more professional feel. These being on castors make them super easy to move into position and roll off to the side when not in use. They are stable, much more than the folding screens I have tried in the past. That they are connected by the middle piece and not the top/bottom of each other allows you to adjust the positioning to your needs. Overall, this did exactly what I needed and was an affordable option. I also like that they are highly portable: if you want to take them for a booth or event, the poles all disassemble into manageable lengths that easily fit in a car and take very little time to set up again. The only thing I would change is to include a bag to store them in for transportation.

if you are going to be moving them a lot, buy something more sturdy.
Color: Black, Size: Wheel-6 Panel
I use these at our churchc. They are pretty good, not terribly study and the screw that hold the faabric have pulled out in a couple of places. But they wqould work especially well if you were not constantly moving them as we do. They are a bit of a pain to assemble.
