I really like this angled nozzle, especially the sturdy metal construction and small size. I use it with my cordless drill when there isn't enough room to mount my drill press and drill then I come in from the side with this angled attachment. My 12 volt Bosch drill is rated for 265 in-lbs of torque and the Milwaukee bit is rated for 235 in-lbs so they match up pretty well. The spec sheet lists a few more limitations: - Screws up to #8 x 3" - Flat drills up to 1" diameter [blade drill bits] - Twist drills up to 1/8" [I think these work well with large bits - finally say it can work with a 1" bit!] - 1750 rpm max - not for impact wrenches or mains powered power tools. My regular hex bit holder allows me to insert hex bits into the chuck without pulling on the Ring forward but not with this chuck.So you always need two hands on the chuck to insert and remove bits which is a bit awkward.If you are really tight on space you can use very short hex bits, around 1". long. Total space required for the bit + drill is about 2-3/8"", not including the extra space that the drill may need. The inside of the chuck is highly magnetic, but only after the bit is fully inserted. When using very short bits, very few bits stick out of the chuck to hold on to. To break the significant magnetic force, you may need to use pliers to grab the short bits, but regular bits are easily pulled out by hand (after you've pulled out the collet). The overall length of the tool is 6-3/16 inches including the full length of the driveshaft. I have used this rectangular electric wire hole drill with a 5/8" Irwin Speedbor, lead screw type and three spiral flutes. These drills require a lot of torque and the 5/8" Speedbor is the largest speedbor I can use with my cordless drill without overloading the drill. Leaving the speedbor stuck in the hole can cause kickback and extra stress. Please note that the bit drive shaft comes in two different diameters: the extreme end has a 1/4" hex shank, but further down the shaft it widens to 5/16" which is said to accommodate higher-end applications Torque can be used. The red handle is quite adjustable. By unscrewing the handle a few turns, you can rotate the handle from 0 to 90 degrees from the nozzle body (in four steps) and then tighten the handle to lock it in place (a total of 12 locks as the clamp rotates around the nozzle body) . Rotate the collar, loosen the red handle, tilt fully toward the end of the chuck (more than 90 degrees to unlock the rotating collar), then rotate the handle/ring assembly around the bit body. Once you tilt the handle back, it locks the yoke, then tighten the handle itself. Another non-obvious feature: in the body of the nozzle at the end of the cartridge there is a small hole, which according to the instructions is a lubrication hole. for light oil or lithium grease. It's not clear how to use this connector as there is no connector, just a small hole. The product packaging states that the nozzle is made in Taiwan. Despite the high price, the Milwaukee contra-angle is very well made. In general I like it very much, I recommend it.
