National Spline Drive Inverted Spotfacers and Pilots
National Spline-Drive Inverted Spotfacers combine Ruggedness,
Positive Driving and Accurate Alignment with long life and easy
assembly. Hardened and Ground Alloy Steel Pilots fit snugly in
the cutters, while driving is accomplished through splines that
are part of the pilot. These splines bear against slots in the
cutter, giving an equalized drive with all the advantages of the
ordinary spline shaft drive.
The cutter is retained by solid shoulders on the pilot, yet
removal of the cutter is very easy. All that is necessary is to
turn the cutter backwards on the pilot a small distance, then
slide it off. Pilots have a spiral oil groove to facilitate proper
lubrication.
