A regular maintenance program should
be set up for each chuck. Keeping your
chuck clean and grit free will help
maintain drill concentricity and lengthen the life
of your chucks. For detailed cleaning
instruction,
See Maintenance page 25.
XT-3000 CHUCKS
The XT-3000 jaw chuck system was designed
with accuracy and simplicity in mind. As a result,
the XT-3000 chuck allows you to cover a large
diameter range of drills without the aid of
individual collets. You can quickly change from
the largest drill diameter to the smallest in
seconds. The accuracy of the chuck will produce
drills that exceed ANSI, NAS 907 & & ISO 10899
standards. The various chucks and accessories
have drill diameter capabilities that range
from .125 – 1.1875 (3mm to 30mm).
Make sure large drills are secure
after tightening the chuck.
Morse Taper drills:
To secure a Morse Taper drill in the chuck, it is
necessary for the drill to have a minimum flute
length of 4.000 inches. The taper will then be
free from the grasp of the jaws, eliminating
interference with the larger tapered shank. The
other option for holding these types of drills is a
split bushing. Bush the body of the drill up to or
larger than the interfering diameter.
End Mill shank drills:
Typically, an end mill drill has a shank diameter
larger than the body of the drill.
Some End Mill shank drills can be sharpened on
the XT-3000, depending on the length of the
flute verses the length of the shank.
CHUCK DISASSEMBLY &
MAINTENANCE
The use of a dust extraction system while
grinding will help reduce the amount of
maintenance necessary, however,
periodically the chuck assembly should be
disassembled and cleaned. We recommend
the Darex dust extraction system.
