Excessive cutter noise, chatter, poor nish
and tool wear are often the result of too
high a feed rate, and/or too high a spindle
speed. If unsure, go slow!
INSTALLING & REMOVING TOOLING
The spindle and drawbar are designed for R-8 taper
collets, drill chucks and other arbors with the standard
7/16”-20 internal thread.
To install a tool, install the R-8 device (collet or arbor) in
the spindle bore, then thread the drawbar into it by as
many turns as it takes to bottom-out the drawbar head
on top of the spindle, Figure 3-3. (Washers may be re-
quired if the device's internal thread is too short, or dam-
aged.) While holding the spindle collar stationary with
the supplied wrench, Figure 3-4, tighten the drawbar
with a 21 mm socket wrench.
To remove the R-8 device, loosen the drawbar then tap
it with a brass or dead-blow hammer to unseat the taper.
Unscrew the drawbar by turning the upper nut with one
hand while supporting the R-8 device with the other.
Keep in mind that the table, vise and work-
piece can be damaged by falling tools and
drill chucks. The cutting tool itself can also
be damaged in the same way.
