Bosch GBH2-28L Bulldog Xtreme Max Best Overall
- Tool Weight
- 6.4 lb
- Max Capacity
- 1-1/8 inches
- Power Source
- Corded, 8.5 amp
- Impact Energy
- 2.4 ft-lbs
Corded rotary hammers are usually heavy, and the light ones are usually cordless and short of power, which is why the Bulldog caught us first on weight. It comes in at 6.4 pounds with an 8.5-amp motor behind 2.4 ft-lbs of impact energy, enough to make anchor holes in old concrete a short job instead of an afternoon. What earns it the top spot, though, is KickBack Control: a sensor cuts rotation the instant a bit binds, and rebar is exactly where that happens.
The counter-balanced vibration control is the second thing we appreciated. Long chipping runs are where a hammer's vibration works into your hands, and this one stays civil through them. Vario-Lock then rotates and locks the chisel at whatever angle the work needs, so the tool scrapes a floor as readily as it hammers a wall, and the variable-speed trigger with reverse lets you start a bit gently instead of skating it across the surface.
The one thing it can't do is follow you to a site with no power. That's the whole case for the Milwaukee 2712-20, which gives up about a third of the impact energy to cut the cord. Everywhere else the trade favors corded: the last hole of the day drills exactly like the first, and there's no pack to buy, charge, or replace.
What We Like
- KickBack Control stops rotation when a bit binds
- 6.4 pounds is light for a corded hammer
- Vario-Lock sets the chisel at any angle
- Corded power that never fades as you work
Worth Noting
- Caps out at 1-1/8 inches on SDS-Plus bits
Our default for concrete and masonry: corded power, 6.4 pounds in the hand, and kickback control that keeps a bound bit from getting away from you.
