Product Description

These extended-length drill bits meet National Aerospace Standards (NAS) 907 Type B for drill bits used in aircraft repair and production. The bits have a bright finish that is not affected when their cutting edges are resharpened. Spiral-flute drill bits evacuate chips as the bits drill into a workpiece. These bits do not have coolant holes, so a separate hose is required to bring coolant to the bits' tip if it is needed.
