Model G0704 (Mfg. Since 08/11)
your model g0704 features an r-8 spindle taper,
which gives the freedom to use standard r-8
cutting tools and collets. these optional collets
come in many sizes, typically ranging from
1 ⁄
16
" to
7 ⁄
8
" and 3mm to 20mm, and should be matched to
your cutting tool shank size.
To install the tooling:
1. disConneCt mill/drill From poWer!
2. remove the drawbar cap.
3. Carefully clean the surface of the tooling and
spindle taper. ensure that it is free of debris
and is lightly oiled.
4. if you are using a cutting tool and collet, insert
the cutting tool into the collet, then insert the
collet up into the spindle taper, making sure
the slot in the collet lines up with the pin in the
spindle.
if you are using a cutting tool that installs
directly into the spindle, insert the tool into the
spindle taper, making sure the slot in the tool
lines up with the pin in the spindle.
5. slide the tooling upward until it makes con-
tact with the drawbar threads.
6. hand thread the drawbar into the tooling until
the tooling draws up into the spindle taper.
7. use the included spindle pin to prevent the
spindle from turning while you use an 8mm
wrench to tighten the drawbar.
Note: Do not overtighten the drawbar.
Overtightening makes collet removal difficult
and will damage the drawbar threads, collet,
and the spindle taper. Keep in mind that the
taper keeps the collet and tool in place. The
drawbar simply aids in seating the taper.
Loading Tooling
To remove the collet:
1. disConneCt mill/drill From poWer!
2. remove the drawbar cap.
3. lock the quill in place with the quill lock
lever.
4. use the included spindle pin to prevent the
spindle from turning while you use an 8mm
wrench to loosen the drawbar 2–3 turns. do
not continue loosening the drawbar without

spindle.
LAcERATION HAzARD!
Leading edges of end mills
and other cutting tools can
be very sharp. protect your
hands with gloves or a shop
towel when handling.
5. protect the table surface with a piece of
cardboard and hold the cutter/tool with a
shop towel to prevent it from falling out of the
collet. Continue loosening the drawbar until
the collet is freed from the spindle.
NOTICE
The Model G0704 drawbar will extract the
arbor from the spindle. Once the arbor or
collet has broken free from the spindle
taper, be sure to properly support it while
continuing to loosen the drawbar. failure
to properly support the arbor or collet
while loosening the drawbar will result in
the arbor or collet falling out of the spindle,
causing damage to machine components.
