The Bosch RH328VC

The Bosch RH328VC is an SDC plus 1-1/8 inches rotary hammer drill that provides optimal impact energy, power, comfort and drilling speed to attain ideal efficiency and performance. For you to complete your drilling and chiseling operations fast, the drilling tool has a high ratio of power to weight that when coupled with vibration control feature, leads to superior performance. You can attain versatility, thanks to the tool’s embedded clutch.

The rotary hammer drill works in three integral modes, namely: hammer only, rotary hammer androtation only. You can select the three modes through the multi-function selector feature on the drill. The auxiliary handle embedded on the tool allows for easy, flexible and comfortable grip. With the carrying case, your device can be used on the go. With intact performance, the drill features a vibration control setting that works in two steps to reduce vibrations that come from the effect of the tool’s working mechanism.

The vibration, if not controlled, can progress to the tool’s handle that is covered in materials made of dampening rubber, leading to errors. The hammer drill weighs 7.7 pounds and features a variable speed trigger that is powered by a motor of 8 amps. The tool’s high impact energy of 2.6ft./lbs and excellent ratio of power to weight make it one of the best in the market.

The variable speed of 0 to 4,000 BPM on the maximum end and 0 to 900 RPM that is triggered using 3 fingers contribute to precise bit operations and give you better control of your drilling tasks.

The Bosch 11255VSR

The Bosch 11255VSR is a rotary hammer drill that uses the BULLDOG Xtreme technology to offer better performance and speed unlike other brands in the market. Just like the Bosch RH328VC model, the tool comes with multi-function selector to activate any of the three modes of operation: hammer only, rotary hammer and rotation only. You can enhance your working angle using the Vario-Lock Positioning feature that rotates chisel and locks it in approximately 36 unique positions.

The patented brush plate rotates to offer similar power whether the tool is working in a forward or reverse manner. A prolonged cord life and increased flexibility is achieved through the cord turret feature that has a pivot embedded at 35 degrees. Just like the previous model, this tool has SDS-plus bit system that automatically locks bits, and offers dust protection, in addition to its high transfer rate of energy.

Remove round bits and fasteners, and attain precise bit starting using the reversing trigger that works at variable speeds. Reduce torque reaction using the integral clutch feature and enjoy greater control and comfort during overhead drilling operations, thanks to the tool’s D-handle.


The Bosch 11255VSR has a powerful motor of 7.5 amps and a high impact 2.2ft.lbs speed. This means that this drilling tool is less powerful than the RH328VC model. If you want a more powerful yet versatile tool for your varied applications, go for the Bosch RH328VC rotary hammer drill. However, if your drilling needs are simple and not heavy-duty, go for the Bosch 11255VSR drilling tool.

Whichever rotary hammer drill you opt for will help satisfy your drilling needs.
