The Sunex Tools 1" Compact Super-Duty Impact w/ 6" Anvil, No. SX4360-6, offers power while only weighing 15.9 lbs. Despite the low weight, the SX4360-6 produces 1,600 ft/lbs of torque. The ergonomic back handle tilts upward, offering a more comfortable working grip in the drop-position and eliminating contorted wrists and aching backs, according to the company.
