R-8 Collets - Shop fox M1111 Owner's Manual

R-8 Collets

LACERATION
Leading edges of end mills
and other cutting tools can
be very sharp. Protect your
hands with gloves or a shop
towel when handling.
Your Model M1111 features an R-8 spindle taper,
which gives the freedom to use standard R-8
collets.
To install the R-8 collet, do these steps:
1. DISCONNECT THE MILL FROM POWER!
2. Unscrew the drawbar cap.
3. Carefully clean the surface of the collet and
spindle taper. Ensure that they are free of
debris and are lightly oiled.
4. Insert the cutting tool into the collet, then
insert the collet up into the spindle taper.
5. Rotate the collet so it engages the align-
ment pin inside of the spindle, then slide the
collet upward until it makes contact with the
drawbar threads.
6. While supporting the tool in the collet with
one hand, thread the drawbar into the collet
until the collet draws up into the spindle
taper.
7. Snug the drawbar with the A 17MM wrench in
your opposite hand.
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.
To remove the collet, do these steps:
1. DISCONNECT THE MILL FROM POWER!
HAZARD!
2. Tighten the headstock lock.
3. Protect the table surface with a piece of
cardboard or hold the cutter/tool with a
shop towel to prevent it from falling out of
the collet.
4. Using the drawbar hex wrench, loosen the
drawbar but DO NOT remove it.
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.
