R-8 Collets
The Model G0463 features an R-8 spindle taper,
which only accepts R-8 collets. R-8 collets come
in many sizes, typically ranging from
and 3mm to 20mm. You will need a collet to match
the diameter of the shank of the tool you want to
hold.
To install the R-8 collet:
1.
UNPLUG THE MILL/DRILL!
2.
Remove the drawbar cap.
3.
Carefully clean the surface of the collet and
spindle taper. Ensure that it is free of debris,
oil and grease of any kind.
4.
Insert the cutting tool into the collet.
5.
Insert the collet up into the spindle taper.
6.
Slide the collet the rest of the way in until it
makes contact with the threads at the end of
the drawbar.
7.
Using your fingers, thread the drawbar into
the collet until the collet draws up into the
spindle taper.
8.
While supporting the tool in the collet with
one hand, tighten the drawbar with the 17mm
wrench in your opposite hand.
Note: Do not overtighten the drawbar.
Overtightening makes collet removal difficult
and causes damage to the drawbar threads,
collet, and the spindle taper. Keep in mind the
taper keeps the collet and tool in place. The
drawbar simply aids in seating the taper.

3.
Protect the table surface with a piece of
cardboard or hold the cutter or tool with a
shop towel to prevent it from falling out of the
collet.
4.
Using the 17mm wrench, loosen the drawbar
but DO NOT remove it.
DO NOT completely unscrew the drawbar
before striking it with the hammer. You will
damage the threads on the drawbar and the
arbor.
5.
Using the brass hammer, tap the drawbar to
unseat the taper.
6.
Unscrew the rest of the drawbar by hand and
remove the collet.
Note: When not in use, always remove
collets and cutting tools from the spindle
taper. Oxidation may cause the collet to seize
and make it hard to remove later.
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.
