What causes burning on the edge of boards when using the router?

Chris Marshall: If your router doesn’t haven’t have variable-speed control, it could be spinning the bits too quickly … and fast cutters held against wood equals heat buildup and burning. The faster the cutter gets through the wood, the less heat it builds up.

What are router bits coated in?

Many new router bits, as well as pricier cutting tools, such as end mills or some drill bits, are coated with a thick layer of some kind of waxy, oily, plasticky protective material.

Astra Coated tools are effective in wood, metals, aluminum, brass, and plastics, allowing faster speed and feed rates. Astra Coating can also reduce dust and pitch build up, but when it does occur, the bit can be easily cleaned using solvents or bit cleaning solution as it is chemical resistant.
