How does Bits & Bits’ Astra Coating extend the life of your bits?
During any type of cutting process, the cutting bit endures heat created by the friction and abrasion of the bit moving through the material. This friction and abrasion is a major cause of bit wear, resulting in the cutting edge dulling or deteriorating, causing burning, a rough finish and vibration.
Astra Coating is an applied multi-layered surface coating that lowers the friction coefficient of the bit, which allows the bit to cut smoother and faster while keeping friction heat down. This in turn will extend the life of the bit. Astra Coating is effective in wood, metals, aluminum, brass, and plastics, allowing faster speed and feed rates.
