This handy tool combines all the power and vibration of an air hammer, with all of the attributes of a 1/2" drive impact driver. For a seized fastener, especially if it’s countersunk, the traditional remedy has been the impact driver. But what happens when even an impact driver cannot budge that seized screw? Laser have a new type of impact driver (part number 6064), designed to work with an air hammer, and this new tool combines the massive hammering force with the impact driver’s turning action This bi-directional impact driver also features a half inch square drive, and when used with an impact socket, the tightest nut or bolt will soon yield. It also works with both left and right-hand threads and is particularly suited to the Laser 6031 air hammer (sold separately). The kit includes a soft rubber coated side handle, the air hammer adaptor and four 5/16" hex shank bits: Phillips PH2 and PH4 and flat 8mm and 10mm.
