Makita Makita 451329-1 Dust Extracting Nozzle, KP0800K

It attaches to Makita KP0800K planer with one screw and replaces the existing nozzle (which is nothing but dust reflector). Planer connected to a vacuum works way, way better than planer which ejects dust on the floor (with the exception of cases when you work outside). I am puzzled why it was not a standard part of the kit.Diameter of the nozzle follows metric standard using in Europe (or Japan), it is 50 mm outside diameter (slightly less than 2 inches). US vacuum hoses are typically 2 1/4 " and their connectors are too large for this nozzle. In contrast, connector on my Festool 36 mm hose fits into it perfectly, it is exactly the same dust port as on the Kapex or on the HL850 planer. For those who do not own Festool vacuum / hoses, the only option is several layers of painters tape on top of the nozzle to achieve a tight fit. Adapters sold in stores are made to ASE units and do not readily fit metric sized nozzle, neither inside nor outside, although one user in the "answers" section reported that he was able to make one of the standard adapters work.I rated it 5 * because the planer is much more fun to work with when you are not covered with wood shavings and do not breath in wood dust, and because I could use a flexible Festool hose which I had at hand, but many other users will probably be frustrated with its sizing and mismatch with their vacuum.With this nozzle and vacuum, efficiency of dust collection is excellent. I did not compare it to Festool under all conditions (I use only Festool for any fine work), but when it comes to flattening the floor, both Makita and Festool perform the same in terms of dust collection, with the same vacuum. There are barely any shavings left on the floor.Added in July 2015: Bosch makes an adapter "Bosch VAC003" or "Bosch VAC020", for conversion of 35 mm to 1 1/4 or 2 1/2 inch hoses. These adapters can be purchased for about $7 on Amazon. Both of them can be used to connect this nozzle to a US-sized vacuum hose. Note, however, that 2 1/2" hose is way too big and ridgid for use with a hand tool. It will be more of a struggle than a benefit. You also can buy a Bosch vacuum hose VAC0005, it is long (5 meters) and has a friction fit connector on the other end which plugs into any US-standard shop vacuum with friction connector. It is just the right size for use with a planer.

The planer it attaches to is an absolute mess without a way to capture the chips.This works great with a chip bag or connected to a dust collector

Be warned, it's darn hard to find a hose that fits this thing.... Honestly pretty lame that this piece is not included with the planer itself.4 stars because the part itself is as described, but... ugh.

This fit my Makita saw perfectly. Product is well made.

Bought this to adapt my Makita planer for vacuum. I was looking at the manual and it also showed a little elbow so I would recommend purchasing the elbow adapter as well to avoid having difficulties adapting to the hose. Hooked up perfectly with the hose once the elbow was installed.My main complaint is Makita’s failure to identify the part numbers needed on their manual. So to summarize - if you get the dust/vacuum adapter you should also look for the elbow adapter!

Should be included with the purchase of the planer but needed it and does the job connection to my shopvac

The media could not be loaded. What I don't understand is why this hose adapter wasn't part of the planer in the first place. Sadly, I still had to adapt the vacuum hose to the fitting as the size didn't fit any adapters that I had

Perfect fit, well made, and just what I needed. It is not a standard hose size, but I found a connection to fit. Wish I would have bought it sooner.
