Review on Trimming Cutting Adaptor Trimmer Tackpro by Drew Springer

They worked as described. However, the set screw broke off after several replacements. The tool was sharp enough, but the tolerance wasn't precise. I noticed that it didn't cut the brass flush. This is due to the tolerance of the cutter to the shaft. This was very easy but a little sanding is required or the handle will have a little play when reassembling. I'm pretty sure it's the router as I used the shank on another Pen State router after drilling and removing the stripped set screw. But what can you expect for the price. The tolerance and set screw is why I gave it 3 stars. If you buy this 1, do not use the included Allen screw or wrench. Just go to a hardware store and buy a good set and a better set screw made of a harder material and check the handle tube for drill bits before assembly.
