The power train gears and
spline shafts are made of
the finest quality, heat
treated and ground nickel
chrome steelgiving extra
strength and smoothness to
high torque loads
The spindle is made of the
finest case hardened steel,
for extra strength and wear
The spindle is supported
by double row taper roller
and thrust ball bearings at
the nose, with thrust and
radial axis bearings at the
top
Built to withstand
exceptionally heavy drilling
and boring loads and to
insure maximum accuracy
Arm raising safety device
prevents arm from dropping |

Transmission combines
variable speed pulleys with
a steel pinion gear for full
torque
Non-slip power drives
tools at nearly 100% of
available horse power
Head is massively
constructed for more
accuracy and rigidity
Spindle is fully enclosed
in an oversized 3" quill
minimizes tool deflection
Quill supported by heavy
duty ball bearings and
tapered roller bearings
