Molybdenum Coated: molybdenum cools and lubricates the bit. The bit stays sharper longer because the heat treatment lasts longer. The bit ejects chips and bores faster than ordinary bits and binds less, even in wet or resinous woods.
Deeper lands: for a stronger less flexible bit.
Extensions: two recesses on shank to receive extension set screws.
