Coated Roundover Router Bits: What Is the Advantage of Yellow Coating

Explain the function of yellow coating on roundover router bits,

Yellow coated roundover router bits are upgraded versions of standard wood milling cutters. The surface coating reduces friction between cutting edges and wood material. It prevents wood resin and sawdust from sticking on blades during high-speed milling. Even bits with carbide inserts for router bits gain extra protection from this coating. Without coating, wood debris easily sticks to cutter edges, causing wood burning and rough finished edges. Coated roundover router bits keep cutting smooth at high speed, lessening frequent cleaning work. These coated bits are suitable for continuous batch processing in furniture factories. They perform steadily on density board, plywood and solid wood. When comparing tools, coated roundover bits are worth considering if you run long-hour milling tasks every day.
