the collet nut. The maximum end mill diameter that you can use with your Nomad 3 is 7mm (0.275
″
); make sure to
purchase an appropriately sized collet.
What if I Want to Use Smaller End Mills?
In the Carbide 3D Shop, we offer several small cutting-diameter end mills:
1
/
16
″
(0.0625
″
),
1
/
32
″
(0.0312
″
), and 2mm
single flute (0.078
″
) end mills. Because they all have a
1
/
8
″
shank, they can be used with your
1
/
8
″
collet.
You can also purchase smaller ER-11 collets if you decide you want to purchase end mills with shank smaller than
1
/
8
″
. You just need to make sure that the collet is appropriately sized for the end mill you want to use. For example,
you’ll need a
1
/
16
″
collet for an end mill with a
1
/
16
″
shank and a
1
/
32
″
collet for an end mill with a
1
/
32
″
shank.
What are the Parts of an End Mill?
Shank: The diameter of the
non-cutting end of the
cutter.
Overall Length (OAL): The
total length of the cutter
(measured from tip to tip).
Length of Cut (LOC): The
total length of the cutting surface of the cutter. If this dimension is less than the dimension of the shank, the LOC is
effectively how far down the cutter can plunge (total) into the material.
Flutes: The number of cutting surfaces found on the cutter. For example, a 2-flute cutter has two cutting edges, a
3-flute cutter has three cutting edges.
Cutting Diameter: The diameter of the cutting area of the end mill (can be different from the shank size).
What Are Common End Mill
Varieties?
End mills generally come in two
varieties: square (right) and ballnose
(left) end mills. Watch the
Aside from the shape of the end mill,
the tip geometry also varies between
types, determining the way the chips
are ejected and effecting the
smoothness of the finish.
NOTE:
The Nomad 3 does not use a proprietary system for end mills. That means that any end mill, from any
vendor will work. Just make sure you get the correct shank size for your collet.
