Description of π¨ Yonico 15231 4 Inch Plywood Tongue: A Trustworthy Tool for Precise Woodworking
5.2mm Tongue and Groove for 1/4" Plywood center panel. Create tongue and groove door frames for 1/4" thick plywood center panels. Premium C3 micro-grain tungsten carbide blades for a sharper & longer lasting edge. For use on table mount router only. Silver induction brazing for maximum strength and durability.
This set cuts smoothly and makes for a great connection. Once properly configured, they work great. As with all things woodworking, it comes down to fine tuning to get good results.
Please note that these nozzles are for 1/4 inch thick plywood purchased from a large store. Plywood for large boxes 5.1mm. If you are using real plywood that is 1/4" (6.1 mm) thick, this bit set will not work. The rest of the bits worked fine.
Very good product but I have a tongue and groove cutter and was looking for a vibrating device to make doors. This cutter is not suitable for this. The cutter on the underside for cutting the rail needs to be a bit thicker. Found out the company didn't have the cutter I was looking for. The next has a slight bevel. Overall a good product.
