The
milling machine makes an excellent precision drilling machine. Accurate
positioning on both the "X" and "Y" axis provide a simple way to locate
holes, and although the milling machine does not have a quill feed, the
"Z" axis feed screw does give you micrometer accuracy for depth control.
The DRILL CHUCK is similar to the tailstock chuck used with the lathe in
that it is a 1/23" (.79mm) to 1/4" (6.35mm) Jacobs chuck mounted on a #1
Morse arbor. The difference is that this arbor has been drilled and
tapped for a drawbolt. The drawbolt prevents the arbor from working
loose druing use.
Note: This chuck is NOT designed for lateral loads and should not be used for holding end mill cutters.
The DRILL CHUCK comes complete with key, #1 Morse arbor, drawbolt, and
thrust washer.
