The new RH540M SDS-Max rotary hammer from Bosch provides maximum productivity in all day drilling and chiseling applications. At 6.1 ft. lbs. of impact energy (E.P.T.A), the new RH540M provides up to 30% more impact energy versus the previous model for best in class performance. The RH450M also provides variable speed for better bit control during application start-up. Includes SDS-Max and Spline Chiseling Dust Collection Attachment. The HDC300 is a unique dust collection attachment which will fit on all Bosch SDS-max, spline combination rotary and demolition hammers with exception of the 11316EVS SDS-Max Demolition Hammer. The HDC300 is unique in that it allows the user to access the chisel for installation, removal and/or adjustment without removing the attachment. The shroud itself focuses air suction from the vacuum around the chisel for maximum dust collection. The attachment also features a metal extension arm which can be adjusted forwards or backwards to position it correctly around the chisel and to accommodate different chisel lengths. The metal arm also provides added job-site durability. The shroud features a convenient rubber bumper at the tip of the shroud to provide cushion should it contact the work piece during use. The HDC300 comes in a kit that includes an extension tube and 3 adaptors to fit different sized hammers.

Already had a Bosch Bull Dog but needed to have the ability to drill bigger holes without going to a spline bit. Bought the SDS Plus adapter so I can use the smaller bit’s with this drill without having both drills out at the same time.

This is a very good and heavy duty SDS Max hammer drill. Most recently I got to test it for a variety of jobs around my house. I used it to chip out asphalt, to cut paver bricks, and to drill holes in a concrete wall. I have attached a video to show at least one job. The power of this item is very good, with the ability to easily cut through all of the above listed materials. The construction of this tool is very strong as the environment which one would use this is generally not a forgiving work environment. Lots of dirt, and garbage around, and most times one is not treating the tools like babies. Get the job done is the mantra, so the tools can take a hit. This one though, should last for a real long time.The clutch which protects both you and the hammer drill, is not too slippy, but not too strong. It is well adjusted to release only under a fairly hi stuck loading factor (like you forgot to switch to hammer only while using a chisel).Take a look at the video, as this shows its ease of use cutting some pavers. I highly rate this one…

I do a lot of remodeling and keeping dust down is always a challenge especially when you are drilling into concrete I was a little apprehensive when I opened the box this attachment looked somewhat awkward but after taking it out and attaching it to my rotary hammer I found it very easy to install and use it works great and keeps the dust and debris down to a minamul

I have been using this product for the past month or so doing with it whatever it’s capable of doing. I purchased a 8 bits for it to do various tasks and to test it’s limits. I first used a Bosch clay spade to help with the hard clay and shale in the bottom of post hole footings and needed to use a point bit but it worked wonders in assisting to dig the hole to the required depth. I have needed to rely on a digging iron in the past and they just tear up your hands and wear you out quickly throwing a 40lb tool into a hole to break up the earth. Now my hands feel great with the exception of the shakes you have from jittering a tool for long periods on hammer mode. The tool has the power to do quite a lot and the pros and cons I personally discovered are as follows:Pros:The tool is of a superior build quality and has the power you should expect from the brand and the price. It has all functions you should expect for a tool in this price range. It feels like a quality tool with quite a bit of heft and though heavy, it initially feels comfortable in your hands. When using the tool vertical, in most cases, the weight of the tool is enough to load the bit as well while you simply just hold the tool instead of using weight packs to assist which helps to not wear the user out so quickly. The chuck is simple to use and tight around the bit to prevent much debris from entering into the chuck. Also, the selector switch is tight and switches with a bit of force and should not easily be forced out of selection while doing tasks.Cons:I would have liked a slightly longer cord but that’s a bit picky. No other major cons except for weight, which is a PRO specifically for using this tool without applying your own force. Apart from the tool specifically, the bit are expensive and I wish some longer lengths were available without the need of an extension which is also an added expense when you need it.I highly recommend this product for many of the heavy duty tasks as breaking through a CMU wall, concrete floor, digging tough earth and many, many more reasons. With that, I strongly urge you to research the bits prior to completely committing to this tool so you understand the expense that comes with it in order to completely use it to its fullest potential.

I never thought I needed something like this until I had to do a job on one of my uncle’s houses and I loved how it focuses air suction from the vacuum and it made it super easy and clean to work with. The Ski-boot style clamping band provided and adjustment onto the hammer tube really well. It has a rubber bumper that provides cushion on shroud tip. I liked overall the ability and ease to use in projects like this.
