LE LEMATEC Air Impact Driver Professional ToolSmall albeit very robust, very hefty air impact driver. Built like a little tank: very solid, very durable and very powerful (13000 RPM, 40 ft.-lbs. Max Torque. Has two-hammer clutch, 1/4” NPT inlet and a hex head. When I hooked it to both of my compressors (one at a time of course; one big compressor and one small one) the impact driver worked with ease. Very simple to operate. It fits perfectly in the hand, has a very good grip, and I appreciate its heftiness, which helps me have better control over the tool. There are “bonus” items that are included with the air driver: among them, a mini air blower gun, which comes in very handy for (in my case) blowing all the saw dust off of my benches, tools, as well as the floor. There are 4 other small attachments as well. The only thing I don’t quite understand is its high price point. On the one hand it is constructed of Chrome-Vanadium steel, tool steel, aluminum, as well as alloy aluminum, and these metals can really add up. In addition to some special plastic and hard rubber. But on the other hand it’s a relatively small tool, so it seems difficult to justify its price. But it IS definitely a high quality tool. And it’s very difficult to know how much it should be when, in truth, the prices for 1/2” air impact drivers are all over the place, ranging from $40-$50 to over $300! So, because the tool is so high quality and does work so well, I for one am willing to give them the benefit of the doubt as regards the price. I realize that that’s easy for me to say as a reviewer, but nonetheless that’s truly how I feel. If it lasts as long as I’m suspecting it will—b/c of its extremely robust build—it’ll definitely turn out to be a good value. If, on the other hand, there are any problems along the way, I’ll be sure to update this review pronto. In the meantime, this air impact driver is very impressive, and definitely seems made to last.
