Torquey & fast, use it often but bit has loosened... August 26, 2009
Cajtar (SoCal, USA)

Although it appears to be a specialty tool for drywallers or deck installers I find myself reaching for this quite often. For those not initiated to screw guns like this and think it's the same as a drill w/ a philips bit, read on...
(sorry for the length, hope its useful info for you)
The screwgun is similar to, but distinctly different than a regular drill. It does have a clutch mechanism but the clutch disengages based on screw depth, not torque (those clicky clutches common on cordless drills are friction-torque type). Think about that for a second, depth not torque - here's why you want one of these guns:
-ever put in a ton of screws while building a fence or a deck? or hanging drywall or tile backer board? or screwing in door jambs?
+this device is specifically for running screws nothing else, so it is fast and effective. The only way to make this task faster is to put a screw feeder on the nose. With this gun and some practice, I can screw down a 3'x5' backboard in well less than 60sec.
-noticed your screws are not sunk evenly and some minor adjustment with the drill or a screwdriver is necessary, or you've overdriven the screw and the head is too deep to effectively hold?
+wood is an especially inconsistent material. Friction, density, knots etc all mean that the amount of torque necessary to drive the screw home is rarely consistent. With this gun, you are putting in maximum torque until the screw is the right depth, then none b/c the clutch disengages. This gun drops torque really fast at the right depth so its hard to overdrive the screw. Because the torque level is high until the right depth, it powers through hard or "sticky" wood with ease.
-had trouble with torque spikes or jerks from a drill while trying to set the screwhead depth accurately?
+the motor on this drill is spinning really fast so the torque output is silky smooth. The clutch engages and disengages smoothly.
Other cool features:
-standard 1/4" bits are used so any type of screw can be driven (philips, robertson, torx, slot etc)
-there's a magnet in the bit holder so it will hold the screw b4 driving
-the gun shape is really comfortable, the trigger is big. It's easy to operate with one hand using your pinky or bottom two fingers on the trigger.
-motor is reversible so if you need to pull out a screw, pop off the depth adjuster and go for it. Depth adjuster pops off just by pulling on it.
-depth adjuster is precise. One click either way adjusts the depth by ~1/64". It keeps its position despite constant use/abuse.
-trigger is variable speed so you can tone it down if you're going into really soft or hard material. It's easy to keep the motor speed pretty constant
-there's enough torque to easily twist off even hardened screws. This is especially true when driving into "stiff" materials like hardibacker, not a problem for typical wood etc. Here, you have to have more technique and either use lower motor speed or set the depth very carefully.
-no need to stop the motor between setting screws, just keep the trigger pulled and allow the clutch to engage and disengage as you drive and then set the screw.
-engaging the clutch is as simple as putting some pressure on the screw. Here's how you use the gun (after you've set the depth adjustment):
1/ put screw on the bit, let the magnet hold it
2/ put screw tip on the target and hold the screw parallel w/ the motor axis
3/ pull the trigger and let the motor spin freely to a high speed (clutch not engaged yet)
4/ push on the back of the gun to engage the clutch, watch as the screw VERY quickly sinks into the material
5/ listen or feel for the clutch start to disengage (chatters like a cordless drill clutch) as the screw hits the right depth. Pull the gun off the screw & you're done.
So why only 3 stars? After a few uses, the bit holder is not as effective. If you pull the gun off the screw at an angle or before the clutch is fully disengaged, sometimes the bit stays with the screw and not in the gun. I'm not a contractor so this minor productivity loss is not a big deal for me, but would be for others... Maybe the Hilti gun (which has good reviews) would do better at this?
Also, the motor @ 2500rpm is noisy.
Summary: fast and comfortable gun which excels at setting screws into a huge variety of materials with a minor problem keeping the bit in the gun's chuck/holder: 3stars.
