Game Changer!

I rarely write reviews, but I feel I need to help spread the word. I'm not sure where I first saw the Woodanchor system. Wherever it was I knew it was a well-executed system that I needed to incorporate. I'm glad I did. Prior to using the system, I had designed a table to use with my CNC machine that used aluminum T-slot channels that I tried to epoxy to a sheet of MDF. I was never happy with that system for a variety of reasons.

It's been a week since I remade my tables incorporating the Woodanchor system and it's truly a game-changer. In a nutshell, EVERYTHING simply WORKS.

Thanks for providing a tool that is truly going to increase my productivity.

Best T-track like system I ever had

I backed the original Kickstarter and recently ran out of hardware. I got a second router bit just to have one permanently with the router lift and another one in my systainer with the OF1400. I use the ToolQuest system for everything I would have used aluminum T-track before and more.I can highly recommend this system.

A new era

Been looking to break free from the limitations of T track. This new system looks to be the answer. The nuts are a little spendy but saves the cost of an aluminum track. No limits on the length of track and excellent holding power. Bit cuts like a dream. Highly recommended.

WoodAnchor Fixturing Slot Router Bit

Great bit. It is a Whiteside which says it all. Very sharp, well balanced and designed to cut a WoodAnchor slot in a single pass. I put it to the test with my CNC router water cooled spindle, Milwaukee table router and Bosch hand held router. In each case I got a nice smooth cut in a single pass with router motors ranging from 2.25 to 3.5 horsepower. I found it to work equally well in MDF, Baltic Birch plywood or fine hardwoods to include oak, maple and beech. I have probably cut over 100 feet of track and the bit still preforms as it did when it was new.

Slot Bit

I used the WoodAnchor fixturing slot bit to make a sliding fence for my router table. It worked perfectly and I'm very happy with the results!
