STUB DRILL BIT

$4.10

 

These are the best sizes, in general, to use for threading the mandrel into the wood. They have 1 3/4″ flute length and the total length is 3 1/16″. The standard wood bit is longer and tends to “wander” if it hits a tight wood grain. There may be some wood or especially acrylic and resins that it will be best to use the threaded inserts because they do not hold threads well and you will experience tear out.
