3. Place the drill bit you will use in the chuck or collet
and secure. (A minimum of 1/2* of the drill shank
should be up in the collet.) Keyless chuck will hold
drills up to 1/8* diameter. Chuck is more flexible on
size than collets. Dremel collets are available in
1/32*,3/32* and 1/8* diameters.

1 Switch setting on Model 395 Variable Speed Moto-Tool.
..
2 Dial setting on Cat. No. 219 Speed Control Attachment with Model 275 Single
Speed Moto- Tool..
NOTE:
"
Model 285 2-speect Moto Tool is being used. all drilling applications should
be perfonned at the low speed.
Remember. this chart is only to be used as a guide. The Indicated settings are only
approximate. The best option for determining speed is to experiment with a scrap
piece of the material being used. Use a speed that works for you.
4. To eliminate side play in the TOOL HOLDER
BRACKET, loosen the BOTTOM NUT on depth shaft.
Tum depth shaft slightly (as shown) and retighten nut.
All side play can be eliminated. Do not turn to the
extent that you create excess friction between depth
shaft and HEAD HOUSING.
Use the DEPTH STOP COLLAR when you wish to drill
holes to a measured depth. A scale on the DEPTH
SHAFT is provided for your convenience. Depth stop
collar will insure that you can drill several holes to the
same depth.
5. SET SCREWS are provided at top and bottom of the
HEAD HOUSING for adjusting to a sliding feel of the
GEAR RACK. Adjust them to the desired tension. If
they are too tight, the return spring will not retum the
Moto- Tool to its up position. In this case, back them off
SUGHTLY. (1/16 of a tum will be .002)
6. Layout hole locations on the workpiece and CENTER
PUNCH at these locations. Center punching will pre-
vent walking of the drill point and insure proper hole
location. The benefits of center punching are less drill
breakage and better hole size tolerance.
