            There are also 2 end mills (1/16 and 3/32) and 3 router bits( .0500, 1/16 & 2.00mm). These tools have been lightly used and still have alot of life left on them.

             All the bits have a 1/8 shank great for CNC machines, hand held motorized tools like Dremel and Roto Zip or drill presses. They have an aprox.  overall lenght of  1 1/2" and all have the correct I.D. rings on them.  All the bits have been ultrasonically cleaned to remove loose debris from the flutes.

            If you need tiny precision holes these are the bits you need. May different types of industries have purchased these sames bits from me. PCB drilling, CNC machining, Watch repair work, Carburator adjustments, Jewelry work, Rail Road modeling, Doll house building and the list can go on.
