Milwaukee WHJJK 49-22-8510 Right Angle Drill Attachment Kit, Red

Grat for getting into tite spots

I like this right-angle attachment a lot, especially the sturdy metal construction and the small size. I use it with my cordless drill when there's not enough space to fit the drill + bit, then I come in from the side with this right-angle attachment. My Bosch 12-volt drill is rated at 265 inch-pounds of torque, and the Milwaukee attachment is rated at 235 inch-pounds, so they are pretty well matched. The product info sheet lists a few other limitations: - drives screws up to #8 x 3" - flat boring bits up to 1" dia [spade bits] - twist drills up to 1/8" [in my opinion, it will easily handle bigger drill bits - after all, they say it can handle a 1" spade bit!] - 1750 rpm max - not for impact drivers or corded power tools The chuck collar has to be pulled forward (outward) both to insert and remove hex bits. With my usual hex bit holder, I can push hex bits into the chuck without pulling the collar forward, but not with this chuck. Therefore you always need two hands at the chuck, inserting and removing bits, a minor inconvenience. If you are really tight on space, you can use the very short hex bits, the ones that are about 1" long. The total required space for the attachment + bit is then about 2-3/8", not including any extra space that the drill might need. The interior of the chuck is strongly magnetic, but only once the bit is fully inserted. When using the very short bits, there's very little of the bit sticking out of the chuck to grab on to. To break the considerable magnetic force, you might need to use pliers to grab short bits, but regular bits are easy to pull out by hand (once you pull out the chuck collar). The overall length of the attachment is 6-3/16", including the full length of the drive shaft. I have used this right-angle attachment to drill holes for electrical wires, using a 5/8" Irwin Speedbor, the kind with the lead screw and three spiral flutes. These drill bits need a lot of torque, and 5/8" is the biggest Speedbor that I can use with my cordless drill without overtaxing the drill. The Milwaukee right-angle attachment handled the torque just fine, although I was extra careful not to let the Speedbor bit bind in the hole, which can cause kickback and extra strain. Note that the attachment's drive shaft has two different diameters: The very end has a 1/4" hex shank, but farther up the shaft, it expands to 5/16" hex, which they say you can use for higher torque applications. The red handle is quite adjustable. By unscrewing the handle a few turns, you can pivot the handle from 0 to 90 degrees from the body of the attachment (in four steps), then tighten the handle to lock it in place. But you can also rotate the metal collar that the handle attaches to, so the handle can stick out of either side of the attachment body, or the top or bottom (there are 12 detents as you rotate the collar all the way around the attachment body). To rotate the collar, loosen the red handle, tilt it all the way towards the chuck end (past 90 degrees, which unlocks the rotating collar), then twist the handle/collar assembly around the body of the attachment. Once you tilt the handle back, it locks the collar, then you tighten the handle itself. One other unobvious feature: There is a small hole in the body of the attachment, at the chuck end, that the instructions say is a lubrication port, for light oil or lithium grease. It's not clear how to use this port, because there is no fitting, just a small hole. The product package says the attachment is made in Taiwan. Although it's pricey, the Milwaukee right-angle attachment is very well made. Overall, I like it a lot, and would recommend it.

Great bit of kit

This is one handy tool to have in your tool arsenal . You never know when you need to get into a tight space. It sure beats using a stubby screwdriver or a 1/4" socket wrench. This is a very well built attachment. I own the Milwaukee off-set screwdriver power head (48-32-2100) that is a little smaller and now the heavy duty right angle attachment (49-22-8510). Both are outstanding tools and perform better then stated. The heavy duty right angle attachment is rated for 235 in. of torque. This is almost full torque on a Milwaukee 3/8" drive, 12V cordless drill and half torque on the Milwaukee 1/2" drive, 18V cordless drill when using low speed on the drills. One needs to remember that these drill attachments are 1/4" hex drives. If you are looking for serious torque, look into purchasing a 3/8" or 1/2" right angle drill. I hope this will clear up some confusion with the reviewers that stated the bits do not stay in the chuck. You might want to go over the instructions to see what you are doing wrong or you are not using 1/4" hex quick release shank bits. The right angle attachment does have a quick release magnetic chuck. When the bit is installed correctly, you can not even pull it out without releasing it with the quick release chuck collar. I have a Craftsman Speed-Lok Drill and Drive set that works perfectly with this, along with the bits that came with it. Here is a quote from the Milwaukee "Inserting Bit Instructions". 1. Pull out the chuck collar. 2. Insert the bit shank all the way into the chuck. (the magnet will help pull it in) 3. Release the chuck collar. 4. Pull on the bit to make sure it is secure. Update 9/11/2017 Just a commit on the guilty of this attachment. I purchased this in 2006 and have used it routinely since. It still works as it has from day one without any problems. When using it just remember to keep the torque spec in mind and you should have trouble free operation.

It's a nice quality item but to make it work with a drill bit (as I needed it) you need an adapter or drill bits with the correct fitting. All in all a great product.
