BOSCH GBH2-28L 1-1/8ft SDS-plus Bulldog Xtreme Max Rotary Hammer

Our review of the BOSCH GBH2-28L rotary hammer with the 6 piece SDS-plus masonry bit set finds a tool built for tradespeople who need power and precision on concrete and hard stone. The bottom line: this combo delivers robust impact energy from an 8.5 amp motor and a wellmatched carbide tipped bit set that starts cleanly and stays cooler, making it a dependable choice for contractors who drill and chisel all day. It is most notable for its smooth, powerful drilling and the durability of the trade bits under frequent heavy use.

Key Features

• Powerful motor: The 8.5 amp motor produces 2.4 ft-lbs of impact energy so the tool drills through concrete and masonry quickly and consistently.
• Kickback control: An integrated sensor stops tool rotation during bit bind-up situations to reduce the risk of sudden torque reaction and improve user safety.
• Counter-balanced vibration control: The counter-balanced design lowers vibration levels for greater comfort during extended drilling or chiseling sessions.
• Optimized flute design: Bosch's flute geometry reduces bit stress and helps keep the bit cooler while also expelling dust more efficiently for sustained cutting performance.
• Diamond ground carbide tips: The harder, centered carbide tips provide precise starts in tile and hard stone and hold up under heavy loads for longer life.
• Robust head construction: The reinforced head and optimized braze provide longevity for high impact applications and repeated professional use.

Who It's For

The GBH2-28L and bit set are aimed at professional contractors, remodelers, and serious DIYers who regularly drill into concrete, block, or hard stone and need a tool that balances power with user comfort. Its kickback control and vibration reduction make it suitable for installers and masons who use a rotary hammer for long stretches.

Those who only perform occasional light drilling into wood or metal may find this hammer overpowered and heavier than a standard drill; for light home projects a compact hammer drill or standard SDS drill may be more economical and easier to store.

Pros & Cons
