Dremel 575 Right Angle Attachment for Rotary Tools, Angle Drill Attachment, Perfect for Grinding, Drilling and Cutting

Mí herramienta no es de la marca Dremel pero aún así le funciona perfectamente y me simplification la vida

Well made. Easy to use. Instructions could be better but not hard to figure out. Paid for itself the first time I needed to get a small buffing wheel into a tight spot.

Unit works perfectly, but is extremely noisy

Pretty easy to use. Could use some lubrication before using. Seems louder when in use. But works as described.

Great for tight places

This adapter works great. The only caveat is that it might be a bit bulky if you're trying to cut something in a tight space. Aside from that, it was very helpful. I didn't find it to be terribly noisy as some have stated in their reviews.

Nice accessories from Dremel

Summary:-----------------If you only need this right angle attachment for relatively light duty tasks that don't require a lot of torque or last for long periods of continuous use and you can tolerate the noise, this may work fine for you. Otherwise, it won't and there's no simple way to make it do so.Detailed Review:-----------------------I'll preface this review with two statements:- This will not make your rotary tool into a right angle die grinder, no matter how powerful your rotary tool may be. This attachment is not designed to accomplish that.- I'm currently undecided on whether to return this Dremel right angle attachment. It works but has issues due to design tradeoffs and assembly mistakes.I'll start with the positives. This right angle attachment should fit any rotary tool with the standard Dremel threads on the front of the housing. It fits fine on my recently manufactured Dremel and Milwaukee M12 rotary tools. It does allow access into tighter spaces, especially when used with the Dremel EZ-Lock mandrel and cutoff wheels for cutting. Once you get it set up to work with your particular rotary tool, it is easier to use again with that same rotary tool in the future. The gears, input/output shafts and bearings all seem to be reasonably good quality metal.Now let's start with the negatives. The first thing you'll notice when trying to use this right angle attachment is that it's a royal pain to get mounted in the proper orientation on your rotary tool. The easiest way to do this is simply just not caring which way the right angle attachment faces when you first install it. Once it's tightened down onto the rotary tool housing you can then completely unscrew the ring around the right angle attachment so that the attachment can come off. Pull the attachment body off and realign it in the orientation you want as you slide it back into the part that is still attached to the rotary tool body. If it will only go partway back on, that is because the square shaft that slides into the adapter that you put on the rotary tool in place of the collet isn't lined up with the adapter. This is easy to address by slowly turning the output shaft on the right angle attachment as you try to slide the right angle attachment back in. Once you have the right angle attachment slid completely back in, tighten the knurled ring to lock it in place. Yes, it's a pain to do this the first time, but once this is done you shouldn't need to do it again.Now that you have the the right angle attachment actually attached, the bigger problems start to become evident. This thing is NOISY. It feels and sounds like it may be about to come apart, even though it's not. This attachment is many times louder than any of my rotary tools, even my older ones. This is due to it having straight cut instead of helical cut gears where the input and output shafts come together. This is a design decision by Dremel. Straight cut gears are cheaper and only exert force radially (around the shafts) where helical cut gears are more expensive and also exert a bit of force axially (parallel to the shafts) requiring design consideration to ensure that axial force doesn't cause other problems. Straight cut gears are also much, much louder.Let me be very clear in setting expectations here. There is no grease or oil that will make these straight cut gears quiet. Good quality grease can make them quieter, especially for a short period after being applied, but they will always be loud.If you read through reviews here, you'll see that the major complaints are due to the noise and the heat. The noise is almost entirely due to the design choice to use straight cut gears. I disassembled the right angle attachment and found that the bearings seem to be of reasonably good quality and the gears are cut reasonably well but are definitely very simple straight cut gears. When my particular right angle attachment was assembled, there was grease injected into the housing but it missed the gears entirely. It was globbed into the opposite end of the housing and that left the gears completely dry and unlubricated. This made the noise even worse, of course. It would also cause the gears to wear out much more quickly and generate a lot more heat while doing so. Since I mentioned it, let's cover the complaints about heat being generated during use. Obviously for this attachment the heat is going to be generated from friction. The friction points are going to be where the gears mesh, in the bearings where the shafts are turning, and anywhere the shafts or gears touch the plastic housing. There thankfully seemed to be relatively little friction from the moving metal parts turning against the housing. The bearings also seem to be good enough so far to not be source of an unexpectedly high amount of heat, although I have less than an hour's actual usage with the attachment so I'll have to wait to see if that stays true over time. That leaves the gears as the primary generator of heat, especially if they are not lubricated like mine weren't from the factory.The last frustration is the need to use another mandrel or other thin shaft to prevent the output shaft of the right angle adapter from turning so that the collet can be tightened. I understand why you can't just use the lock on the rotary tool due to the forces that would be exerted through the attachment, but it seems like a simple button locking mechanism could have been added to the attachment itself for this purpose also.I'll sum up this review with the statement that I'll likely keep this right angle attachment but I'll only use it when I really need to get into a tight space. Now that I've disassembled to see how it's designed, know that the noise isn't from defective parts AND I have lubricated the gears with high quality grease, I'm a bit more confident that it can work fine for relatively light duty tasks that don't require a lot of torque or last for long periods of continuous use. If that's all you need to do, this may work fine for you. If you need more torque, especially like is provided by many of the newest rotary tools from Dremel or Milwaukee or others, or need to use a tool for longer periods of continuous use, don't buy this. You'll just destroy it in relatively short order. Just use a right angle die grinder instead.You also shouldn't buy one of the off brand versions of a right angle Dremel attachment, as there is only one primary design for those and the flexible wire shaft that connects the rotary tool output to the right angle input collapses when you try to tighten the collet on it, which makes that design worse than this Dremel design. Again, just use (buy, if necessary) a right angle die grinder if you really need to do heavier duty work for longer periods. No current right angle attachment for a Dremel or other rotary device is going to hold up.Hopefully this is helpful for those who have read through the massive number of sometimes seemingly conflicting reviews of this attachment. It is noisy, but that's inherent in the design and not necessarily a sign of defective or low quality parts. Excessive noise could be a sign of incorrect assembly that left the gears without grease, as happened with mine, though.
