Senco’s new 445XP Roofing Gun is designed to drive nails quickly and take a beating. Capable of firing 12 nails per second, the gun is equipped with a newly designed firing valve that allows it to use 5% less air than similar models, according to the manufacturer. The gun features a tool-free depth of drive adjustment, a 1/4-inch swivel plug, and a detachable shingle guide. The Senco can hold 120 nails from 3/4 inch to 1 3/4 inch in length. The aluminum housing adds durability yet the tool weighs just 4 1/2 pounds. Price: $229 / COO: Taiwan /
