Bosch RH328VC Review Summary:

Concrete is certainly among the most unforgiving building materials. Those who don’t use the proper heavy artillery against it will undoubtedly lose the battle! That’s precisely why a quality rotary hammer is an inseparable part of every handyman’s toolbox – is Bosch RH328VC worthy of becoming your go-to hammer drill?

Offering a great combination of overall comfort, drilling speed, impact energy, and sheer power, the RH328VC comes packed with a ton of useful features. It has an outstanding power-to-weight ratio, vibration control for increased productivity, an integral clutch, as well as three different modes of operation.

All of these features make the Bosch RH328VC one of the most versatile tools of this type on the market. Nevertheless, we’ve decided to carefully analyze the device and try to find all of its good and bad sides. If you’re interested in results, read on!

RH328VC Specifications:

  • Weight – 9.6lbs
  • Dimensions – 19.2″ x 14.6″ x 5.3″
  • Chuck Size – 1-1/8″
  • Motor Power – 8.0 AMP
  • Voltage – 120 volts

Bosch RH328VC – The Basics

Like many other power tools manufactured by Bosch, this one also provides optimal power, comfort, drilling speed, and impact energy to attain the best performance and efficiency. When we couple this with the unit’s vibration control feature and high power to weight ratio, we get a quality tool that’s bound to become immensely popular.

Working in three integral modes (rotation only, hammer only, and rotary hammer), the motor of this unit achieves the (variable) speed of 900 RPM and 4,100 BPM. It also has an auxiliary handle that allows a comfortable and flexible grip, as well as the tool case for transportation and storage purposes.

The fact that this unit can handle even the most serious DIY projects makes it a very tempting offer. To find out its value for the money, check out the features below.

Bosch RH328VC Features

The Design

The German manufacturer is undoubtedly one of those companies that always try to satisfy the customers with the ergonomic design of their products. The RH328VC is no exception to this rule – it sports the right weight and the shape to be incredibly easy to handle. Using this rotary hammer doesn’t induce arm strains, even when you have to work overhead.

Just like we expected, the RH328VC has a padded grip, as well as the additional auxiliary handle. The auxiliary handle can be rotated for 360 degrees, providing you with a lot of flexibility when it comes to holding the unit during the drilling process.

One thing we particularly liked about the unit’s design is that it comes with the manufacturer’s signature 2-Step Vibration Control. Its purpose is to reduce the vibration that comes from the device’s impact mechanism and then progresses to the handle.


Having the impact energy of 2.6ft/lbs, this model is ideal for hammering and drilling all kinds of tough materials. It can be used in three different modes: rotary hammer mode (best for masonry bits), the rotation-only mode (for wood and metal), and, finally, the hammer-only mode (generates low impact energy).

The unit’s variable speed (0-900 RPM) is there to provide the user with precise drilling and can be modified via the 3-finger trigger. The built-in clutch, on the other hand, minimizes torque, while the Vario-Lock System allows one to lock and rotate the chisel in many different positions.

Warranty & Accessories

The whole package consists of the unit itself, its auxiliary handle, and a handy carrying case. This is the standard deal when it comes to Bosch products and one we can’t complain about. The device is supplied with a 1-year warranty and 30-day money back guarantee, which isn’t that great, especially when we consider the price of the kit.

Things we liked about it

Just like many other power tools manufactured by Bosch, this one excelled in almost all fields we tested it in. The RH328VC is a powerful and well-designed rotary hammer, and using it is a joy. When it comes to the overall ease of operation, we were delighted with the inclusion of an auxiliary handle, as it gives one better control over the device and makes the whole process of drilling a lot easier to handle.

The same goes for the unit’s 2-Step Vibration Control which reduces the vibrations and allows you to be much more precise when using the device. The fact that it has three different operation modes will let you use the RH328VC for a myriad of various DIY tasks, making it one of the most versatile devices of this type on today’s market.


Things we didn’t like

The Bosch RH328VC is among the most expensive rotary hammers we’ve reviewed so far – its price tag inevitably puts it into the category of premium hammer drills. Fortunately, its excellent performance justifies the high price.

Our other complaints include a short warranty and a minor issue we’ve had during the testing. At one occasion, the depth guide slipped and made us drill a hole deeper than required. It happened only once, but it still deserves to be mentioned as a possible issue for some users.

What Users Say About The Bosch RH328VC

The RH328VC has been well-received by users, who are calling it as yet another top-notch product from Bosch. They’re mostly praising the unit’s outstanding versatility, saying that they’re using it for chipping, hammering, and drilling on a daily basis. Consumers consider this drill as a great addition to their power tools, stating that it easily tackles any task they throw at it.

Their only major complaint is the short warranty, although none of the users had any serious issues that required taking advantage of it.


We absolutely loved Bosch RH328VC! It’s an ideal choice for anyone who is looking for a durable, efficient, and versatile tool that’s capable of dealing with even the sturdiest materials without any issues.

The unit works just as advertised, which is precisely what we expected from Bosch – its performance justifies the price tag, and the RH328VC deserves our sincere recommendation.
