Bosch RA1173AT Dust Extraction Kit

Works great on my Bosch 1917 router combo kit! Takes a little longer to setup but no dust is worth it!Light weight so be careful. They may break. It’s plastic as I expected.

This fit my router and greatly reduced dust. There was still a bit that came out of the bottom but the finer dust was almost eliminated and sucked into my Festool. This fit the larger (36mm) hose.

I own the 1617EVS Bosch router. I purchased both this dust collector system, as well as Keen's dust collection system. The fit on the router is very good. For using the router for dado's and such, the side attachment works well. Also included in the kit is an attachment for edge routing that fastens to the base of the router. While this works, I find it rather cumbersome in use, and it's limited to about an inch and a half high router bits. As luck would have it, one of my first project was trimming off the bottom of the door, and I needed a little over an inch and a half, so this was one of the first problems I discovered.There is also a 3rd collection attachment for the plunge base, and I don't see any reason why this should not work well. The plastic is not an antistatic type, so fine dust from MDF or similar composites tend to build up on the plastic, which can obscure the view in some cases.For router tables, the plastic port comes straight off, and as such only allows for about three quarters of an inch thickness. Since most router tables are at least 1 1/4" thick, you probably won't be able to use it without modification to your tabletop. The Port also comes out the front of the router, and I can see where this would make placement of the hose awkward in some cases.So, this attachment has it's place for handheld routing, but for router table work the Keen system is superior. See: Router Table Dust Collection Accessory here on Amazon. Since the plunge base is generally used for handheld work, and the fixed base is used under router tables, I think a redesign by Bosch is in order. Creating a downward angle of about 15° in the adapter would solve the problem, although there still would be the issue of routing the hose.I would advise before purchase one consider your primary use. The keen system would not work well for handheld work. The Keen system totally obscures the view of the router bit. It is made of silicone, and is also angled down by design. It can be rotated to exit the rear or front of the router or any angle really, so again, a superior system for a router table.I ended up keeping both systems, and think they both have their place. Many routers have nothing for dust collection, so it's nice that Bosch has a pretty decent option for handheld work at least.With just a little more engineering this could be the best of both worlds. The Bosch router is my first Bosch tool, and so far I am not overly impressed with it's design. I just had an issue with one of their adapters, that supposedly allows one to use porter cable guide bushings, but the adapter needs and adapter to make it work! bizarre. Sent that one back.For the price, this is probably not a bad purchase, but understand its limitations.

I bought this kit when I bought a new Bosch 2 1/4 HP router. I've only used it on the plunge base, but it works great. I was routing out a bowl and had very little dust. I would highly recommend this kit if you buy the Bosch router. Since I haven't used the Bosch fixed base, I can't comment on how it works.

I have not tried all 3 dust shrouds yet, but have installed each of them on the bases and seem to fit well. Installed on plung base to route datos and picked up 90% of the dust/chips. Attached to a Festool 27mm hose perfectly.

I broke the chip shield on my plunge router, but with the dust hood on it didn't matter. I haven't used the edge hood yet. Fixed base adapter worked fairly well.

The plunge adapter worked great for routing an insert plate opening in MDF, which is otherwise a very messy and hazardous operation. I would say it captured 90% of the dust. Although I haven't tried them, the other adapters are probably not as useful. The edge guide may not work in all situations as the fit on the base is dicey, and for edge forming most woodworkers will use a router table anyway. The adapter for fixed base (which is attached in my router table) is a throw away.The plunge adapter also sits pretty low on the edge, so I could not use the flat edge against a shop made guide, had to make another guide to use against the rounded edge of the base. It does fit on top of the Bosch quick change template adapter, but it has to be removed to access the latch.By carefully supporting and guiding a shop vac hose, I was able to use it directly connected to the plunge adapter, but you have to be mindful not to put too much pressure on relatively thin walled adapter.This product would have been better if the plunge adapter was sold separately for a lot less.

As described.
