To Use... Dull or broken driil bits can be replaced in a few
seconds - without removing Collet from Extension Rod. |
| • |
Efficient and Economical... Three Extension Rods accommodate
a total of 81 interchangeable Collets, covering a range of drils
from 1/16" through 5/16" (.3125 max. dia. shank), and are available
in two standard lengths, 9 inches and 4 inches. Other lengths
available on special order. |
The
individual drill size is clearly stamped on the head of each Collet.
Extension Rods are precision machined from high grade tool steel
and scdientifically heat treated for maximum strength and durability.
Collets are case hardened for wear-resistance. O.D. of the Extension
Rod is greater than the maximum diamater of Collet. Tool can therefore
be used with drilling bushings (B).
