Concord Blades QFA01 Quick Change/Flush Mount Adapter

Will keep it for multi-purpose use, but not adequate for my intended use which was flush-cutting floor nails out of terrazzo. The heads of the screws used to affix the blade jut out on the prone side, so it does not provide a truly flush cut... at least not without digging a few screwhead-sized divots into the surface of whatever you are cutting. In the case of my terrazzo floors, this method--although easier--was ultimately more damaging than manually extracting the nails with a hammer.

I'm a general contractor that specializes in tile, bathrooms and kitchens. It's very important I have a working flush mount system, and appropriate blades. This system works great for the first time. After extensive use and changing oout a blade the screws don't last and end up stripping out. Consequently, I use one of these per blade I have, unmount it from the tool, instead of the blade from this system.

I like everything about this except the bolts that come with it got filled and ground down too much to remove. They also stripped when I was attaching the blade. I think they should be a more robust steel. Overall I still liked the product and would buy another but would buy my own bolts.

This flush adapter is 3/16" too thin to work on a makita. The arbor post will stick through the adapter.The toolcity stainless adapter for a little more $ is just the right thickness as I've compared this to a coworkers tool city adapter.Keep in mind these are really one and done adapters, if you use them religiously the screw heads will disappear. Still cheap with the blade options available.

best I've ever used. Hopefully, they will be re-stocked...

Great system. Used to remove some stem wall flush with the surrounding slab. Worked well.

It works as expected. Fits as it should. Arrived on time.

This has been working great, having the addition of two long screws and nuts adds quite a bit of safety to the whole setup. Even if the screws loosened up the backup nuts would hold the blade securely
