## Customer Reviews

### ⭐⭐⭐⭐⭐ Look No Further!
*by T***. on July 25, 2025*

Best router bit I’v ever owned. Works tremendously well with wood/epoxy resin boards and tables.

### ⭐⭐⭐⭐⭐ This bit is amazing!
*by S***  on April 17, 2025*

I had a customer that wanted a 11’-6” live edge oak office table, I was able to find a 20’ X 8’ slab of 127 year old oak, dried in a warehouse for 5 years so it was rough and very uneven. I am making the entire desk out of this one piece and have been milling it myself, I have used this bit the entire project so far and it is still cutting perfectly flat and not one burn yet and I still have yet to rotate the knives. This bit is absolutely worth the money!!

### ⭐⭐⭐⭐ larger diameter moves more wood
*by E***N on January 14, 2025*

The large 3' cutter makes routing a large slab a lot quicker, it is best to keep the depth of cuts thinner because you are cutting a lot more area at each pass. Like most large cutters it dulls quicker than smaller cutters and has to be cleaned more than small cutters. Great way to speed up processing and does the job well. Minimal sanding to remove cut lines when co0mplete.
