The only way to compensate for #’s 1 and 2 is to bore the
end mill holder to a larger diameter. This will result in
excessive run out when you use the holder for your end
mills. We don’t make oversized end mill holders. You can
use a piece of emery paper to deburr the shaft of the edge
nder, so it doesn’t dig into the end mill holder. In other
words, you are creating a beveled surface so the edge nder
can slide easily into the holder.
Maintenance
When the end mill holder is not in use, make sure it is
treated with a light surface coat of oil to prevent rust. If
the end mill holder does rust, it can be cleaned using a
ScotchBrite
®
or similar abrasive pad. Store wrapped in the
original waxed paper if possible.
End Mill Holders are Available in the Following Sizes:
P/N 3075 5/16" End Mill Holder
P/N 3076 6.0 mm End Mill Holder
P/N 3077 8.0 mm End Mill Holder
P/N 3078 10.0 mm End Mill Holder
P/N 3079 3/8" End Mill Holder
P/N 6079 1/4" End Mill Holder
P/N 6080 3/16" End Mill Holder
P/N 6081 1/8" End Mill Holder
P/N 6082 5/32" End Mill Holder
P/N 6083 1/2" x 1.2" End Mill Holder*
P/N 6086 1/2" x 2" End Mill Holder*
* Please note that when using the 1/2" x 1.2" end mill holder (6083) or the
1/2" x 2" end mill holder (6086), be aware of the length of the shaft of your
cutter. The hole through the spindle is .405" so a long end mill would not be
able to go through the spindle.
The milling collets (P/N 3060) used with the Sherline
vertical mill or vertical milling column are designed to
be used with the Morse #1 taper common to all headstock
spindles manufactured by Sherline. The collets are held
into the spindle with a drawbolt. The set includes 3 collets
and a drawbolt with collar.
These collets have a shallow angle that gives them high
clamping pressure making them ideal for holding cutters.
The shallow angle makes the collet “stick” after the collet
drawbolt is loosened. Back the bolt o a few turns (do not
disengage completely) and lightly tap the head of the bolt with
a hammer or mallet until the collet can be easily removed.
End Mill Holders
Because the hole through the spindle is only a little over
3/8" (10mm), a collet that would accept a 3/8" shank end
mill is impossible to make. End mills with 3/8" shank are
very common and in many cases cost less than the miniature
series. They are available in many sizes and shapes. To
take advantage of this fact, Sherline oers the 3/8" end
mill holder (P/N 3079). (See page 1.)

Removing Rust Preventive Coatings
Milling Collets
Removing Factory Applied Rust Preventives
To prevent rust between manufacturing and the time you
receive your machine, raw steel parts are coated at the
factory with Corlm
®
or an equivalent rust preventive. It
is a little sticky and may have a light brownish color that
looks like surface rust. It’s not rust and is easily removed
with a brush or cloth and some kerosene or odorless paint
thinner. Once the coating is removed, the steel surfaces
should be protected by wiping on a thin coating of light
machine oil, sewing machine oil or “3-in-1” oil. Each
time you are done with a job and before the machine or
accessory is put away for storage, steel parts should again
be coated with a rust preventive or a thin application of
light machine oil to keep surfaces from rusting. This is
particularly important if you live in a humid climate.
Applying and Removing WD40
®
If you apply WD40 or an equivalent rust preventive
during storage, it should be removed by wiping down
with kerosene or thinner before the machine is used again.
Once the coating of WD40 is removed, the parts should
re-coated with light machine oil before use. WD40 is
NOT recommended for use as a lubricant!
PTFE (Teflon) Based Grease
Slides and leadscrews can be lubricated with a PTFE
(Teon) based grease for reduced friction. This clear,
non-staining grease is applied to lubricated surfaces at the
factory. It is available from Sherline in a 3-oz tube as P/N
7550 or it can be found at most auto or home supply stores
under the “SuperLube” or other brand names.
