Review on Wolfride T Shape Milling Hardened Woodworking: Efficient Wood Carving Tool for Precision and Durability by James Roper

I bought these to cut holes in a piece of cabinet quality plywood that I will be using for flooring in my house The cutter is very sharp and cuts a clean 1/4" x 1/2" slot. It works fine on my router table. I don't think I'd want to use it in a manual router. They're aggressive. and can give a dangerous rebound. This rebound can also bend the 1/4" shaft. I am very happy with these beats. I haven't used the tongue cutter yet, so I can't comment on that.
