I have a very good Makita LXT 18v 1/4β adjustable torque impact wrench. I had to buy a 3/8" impact wrench and loved the Milwaukee 2854-20. (I bought a battery adapter, Milwaukee M18 battery for Makita LXT to use newer Milwaukee batteries.) On a whim I bought this adapter. That's incredible! The Milwaukee M18 impact tool gives you very precise control over a wide variety of bolts, particularly 4" T25 construction bolts. The adapter provides extra torque that Makita (or any other percussion tool) simply cannot provide. Drive heavy fasteners into a variety of wood materials quickly, easily and hassle-free. This 3/8" to 1/4" hex screwdriver adapter is very well made, holds the bits securely and shows no signs of wear. I've ridden it very hard and it continues to perform very well. In fact, I'm enjoying using my new Milwaukee tool with the LaBear adapter so much that I probably won't be going back to a Makita driver anytime soon. It is so good. (Another "feature" of the Milwaukee setup with an adapter: running screws frequently without engaging the impactor until the screw is almost fully seated. This allows me very precise control over the fastening process.) I find this one great addition to your 1/4 inch hex trick kit!
