In-Line Boring Bits
Boring Bits are coated with a non-stick coating for longer lasting cutting edge and tool life.
These Amana® dowel drills are coated with Polytetrafluoroethylene (PTFE), a non-stick color coating. In cases where the carbide tip cutting edges are coated, there is no need to sand the coating off before use. Once the tool starts drilling, the coating is cleared off the needed cutting edge right away. The coating reduces the friction between the chip and the body inside the flute and it helps to clear the chips out of the hole during the drilling to create a cooler drilling area with no burning and longer lasting cutting edge.
