Although it is different from the original usage, I use it for the cannon hook of the wood attached to the router set on the table. By reducing the amount of cutting by a single time, planar work could be performed smoothly even with a square with some height due to long blades.
The side of the zinc die casting (depth 50 mm) was used for cutting. I could achieve the purpose because it is sufficient work with an accuracy of about 0.1 mm, but I think that it is difficult when the object is steel. We used the company's two blades at the same time, but the cutting surface was better for the four blade.
