To resharpen fabricated cutting heads:
1. Remove cutting head from machine.
See “Disassembly”, page 36.
2. Use appropriate file. See chart page 38..
Use square, second cut, mill files and cor-
responding flat files depending on cutting
head size.
3. Place cutting head in a soft jaw vise
and file from outside to center. File in
one direction at a 45° angle to the land of
the cutting surface (Figure 22, page 38).
NOTE: Cutting head can be sharp-
ened until the land of the cutting edge is
filed to approximately 1/32" (.794 mm) in
width, then a new cutting head is
required.
4. Remove burrs on inside of cutting
head by honing each vertical land or
running an emery cloth counterclockwise
inside cutting head.
