And lastly, the brand’s signature active vibration control system is incorporated within this power tool which ultimately minimizes vibration and makes every drilling session a whole lot effortless to handle.


What is the Difference between Bosch 11255VSR vs. DEWALT D25263K?

Let’s talk about vibration first. Bosch 11255VSR rumbles quite a bit more than the DEWALT D25263K. It has a vibration rating of 10.6 m/s2. And about its high BPM count, its vibration is absolutely something you’ll be to accept wholeheartedly.

As for the DEWALT D25263K, it’s understandable if there’s small vibration from it. The DEWALT comes with a vibration rating of around 9.8 m/s2 all thanks to its by up to 50%. Regarding of how much power it can give, you’ll surely be able to live with its vibration rating.

As for their SDS-Plus chuck size, the DEWALT’s chuck size fits the largest available size for SDS-Plus chucks of 1 – 1/8 inches so users can still bore wide holes quickly. On the other hand, the Bosch 11255 VSR features a ¾ inch SDS-Plus chuck – and this size of chuck should be durable enough to withstand harsh jobs at home and even commercial settings.

Now let’s discuss about their respective angle position. When it comes to DEWALT D25263K, it’s crucial to get the angle of the chisel appropriate in order to yield clean chisel marks and ultimately finishes. As for the Bosch 11255VSR, because of its vario-lock positioning, users would be able to set the angle of the chisel bit wherever they like. In short, you don’t have to position your body in weird angles to achieve the chisel perfectly aligned with whatever tough material you’re chiseling.

In angling position aspect, the Bosch certainly wins by default since DEWALT can’t implement the same vario-lock system that allows the Bosch unit to do its task. This lock system of the Bosch permits and infinite number of angles to align the chisel bit as well.

And finally, when it comes to power and speed, the DEWALT can provide up to 1,450 RPM and 5350 BPM with an excellent impact force of 3 joules. For Bosch 11255VSR, it has 7.5 amps motor thus it can perform up to 5,800 BPM and 1,300 RPM. It can deliver approximately 2.7 joules which is sufficient for medium-level chiseling applications.

Overall, Bosch simply delivers enough power for most drilling tasks for concrete and wood and comes with sufficient impact energy to fulfill most of your DIY jobs. However, the DEWALT’s superior impact energy makes this model better tool between the two. On the side note, DEWALT will be able to chisel your way through concrete or granite more efficiently compared to Bosch.

Final Thoughts

Between these two brands, we highly suggest getting the DEWALT D25263K. See, there’s no substitute for optimal speed and power for drilling long rebar into tough concrete. Also, its third mode which is the hammering-only mode is highly effective.

On the other hand, the Bosch is quite underpowered and needs patience when chiseling away since it’s quite weak when it comes to concrete and rocks. Now, in order to minimize vibrations when boring or chiseling holes in concrete, the DEWALT’s proprietary active vibration control system minimizes vibrations by up to 50%.

All in all, if you’re seeking for the best entry-level SDS-Plus rotary hammer on the market then the 1 – 1/8 inch SDS-Plus DEWALT is most likely the most suitable power tool for your needs.
