and center punch at these locations.
Center punching will prevent walking of the
drill point and ensure proper hole location.
The benefits of center punching are less
drill breakage and better hole size
tolerance (Fig. 18).
6. Secure the workpiece to the base before
drilling. This will keep the workpiece from
climbing the drill bit or spinning. This will
result in s safer experience and better
quality work. Hold down clamps (not
included) are very good for holding
workpieces, or use a small utility vise for
holding the workpiece when drilling (Fig.
18).
7. Loosen the Height Adjustment Lock lever 7
1/2 turn and move the press on the tube
until drill bit tip is near the workpiece. (A
maximum of 1/4" between drill bit tip and
workpiece is recommended.) Retighten
lock lever.
8. Grasp the Press Handle 12 and pull down
to drill hole.
Helpful hints
When drilling round pieces, use a "V" block or
vise. To drill a hole in the center of a round
piece, a center punch mark is necessary (Fig.
17). Use center punch to make center punch
mark (not included).
Avoid force feeding to such an extent that the
motor speed is noticeably reduced. Also, feed
carefully when approaching point of
breakthrough. This will avoid making ragged
breakthrough edges.
For accurate drilling, lower the tool to a
location where the end of the drill bit is within
1/4" of the workpiece before advancing the
handle for feeding the drill. Using minimum
stroke and center punching at the location to
be drilled will ensure accurate drilling.
Tool Holder
Instructions
NOTE: The drill bits are held in the tool by a
collet system or Dremel 3-jaw chuck. The bit
may be installed before or after the rotary tool
is installed in the drill press.
1. Insert and secure the drill bit into Dremel
rotary tool. See your rotary tool manual for
detailed instructions
2. The small Angle Lock knob 10 and large
Angle Lock knob 11 are used to secure the
tool either vertically or at a 90° angle. Tool
may be used at a 15°, 30°, 45°, 60°, 75° or
90° angle for sanding, polishing or wire
wheel application (Fig. 16).
Loosen the large and small knobs and
rotate the tool, then securely tighten both
angle lock knobs.
3. The Height Adjustment Lever 7 is used to
secure the press on the tube at the proper
height (Fig. 16).
Loosen the lever and move the press/tool
assembly to the desired position, then
tighten the height adjustment lever.

time. Do not hang a tool on hanger assembly
when another tool is mounted in the press.
1. Swing the hanger bail HB away from the
rotary tool body (Fig. 15).
2. Hang the tool hanger bail on the hanger
wire 2 (Fig. 15).
3. Tuck the power cord into the cord holder
3 (Fig. 15).
Making optional hold down clamps
for your Work Station 220
Hold down clamps can be fabricated out of
wood, steel or aluminum, depending on your
application (Fig. 19).
1. Cut or saw material to desired length, width
and height.
2. Drill a hole using a 5/16" or 21/64" drill bit
in the desired location, through the hold
down clamp HD.
3. Mount the hold down clamps HD using a
5/16"-18 x 1-1/2" or 2" length carriage bolts
CB with matching washers WA and wing
nuts WB.
4. Mount to base by sliding the head of the
carriage bolt CB up through the bottom of
the base 8 with the washers and wing nuts
on top.
When using hold down clamps HD on
workpieces larger than 1/4" in thickness,
always use a spacer block SP to support the
back side of the clamp. For the best support,
the spacer block should be cut about 1/8"
shorter in height than the workpiece.
