. This 2 inch chisel can weld or plunge. This 1/2" shank drill uses 4 square profile Tungsten Carbide (TC) cutters. For best results, this large router requires a full-size router, preferably with a router table. I didn't see any chips or defects in the cutter, it was very sharp from a small plastic tube holder. This is very good value for money. I recommend this FLYTUO Brand CNC Router 1/2 Shank Flytuo Plate Alignment Router Bit Carbide Planer Wood Router Bit Woodworking Tool Planer (4 Blades). Good budget TC bit for my woodworking needs. I hope you found the information and my review helpful.
