What I Didn’t Like about Bosch RH328VC

The question should be positive since there are so many good qualities that Bosch RH328VC possesses. However, on a negative note, there are two things that I didn’t like about the Cordless hammer drill. First, the machine only comes with a one-year warranty. I see this as unfair considering how much you pay for the tool. I would prefer if the warranty was three years. Secondly, I have an issue with the battery performance. For example, it’s unsatisfactory to be charging the battery after 4 hours of use. Besides, you have to wait for at least 30 minutes for it to charge. Maybe the only positive thing is that the batteries come two, and you can be charging one as you work with the other.

How Does this Rotary Hammer Drill Compare to Other Comparable Hammer Drills?

• Bosch vs. Milwaukee V28HX: The most notable difference between the two is their voltages. Bosch RH328VC is rated 36V while the Milwaukee V28HX is 24V. However, they both use lithium-ion batteries, and can drill through wood and concrete.

• Bosch vs. Dewalt DC233: The voltage for both brands is the same, 36V. Nevertheless, they differ in BPM and RPM. The Bosch drill has a BPM of 4100 and RPM of 0-940 while the Dewalt has BPM of 4400 and RPM of 1450.

• Bosch vs. Makita XPH102 18V: Both have a powerful four-pole motor of maximum torque speed. Their clear difference is in their weight. The Bosch weighs 9.6lbs while the Makita weighs 3.9lbs. Both can drill through wood and concrete but the Bosch enjoys a higher RPM and BPM.

What Do Users Say About this Drill?

Most users give a positive review. For example, a majority of users like the idea that you can use the power drill to make holes in concrete. The machine is powerful and very effective. The other thing that impresses most users is the ability to choose the mode that one wants. Considering that there are three ways to use Bosch RH328VC, either as a hammer, a drill or a rotary hammer, the use of the machine is versatile. Moreover, you can use it on steel. Perhaps the only concern for most users is the price and the warranty.

Final Thoughts

Looking at the powerful and safety features of Bosch RH328VC, there is no doubt that its one of the best rotary hammer drill machines there is on the market. It’s great for all handymen. Since you can use it as a drill and a hammer, I recommend it for masons, electricians, plumbers, builders, carpenters, and DIY enthusiasts.
