Amana Tool® drill bits feature a special Polytetrafluoroethylene (PTFE) coating, providing a non-stick surface for prolonged cutting edge lifetime and tool life. This coating does not need to be sanded off before use, and is baked on at 570° F to reduce friction during drilling and aid chip removal, resulting in cooler cutting temperatures and prolonged tool life.
