Bosch recently released a new cordless version of their 1-in. Bulldog rotary hammer. The new GBH18V-26K drills faster than the corded model. The 18V model gives users the ability to rotate the chisel, it includes soft start for drilling into softer materials, and has kickback control. The dust extraction attachment, which works off of the battery, will be available in May. The kit, which comes with two Core batteries, charger, auxiliary handle, depth gauge, and carrying case
sells for about $550 online.
