Rabbet Cutting
A rabbet is a groove cut along the edge of a workpiece. This jointer is capable of making rabbet cuts as
deep as 3/4". Depending on the requirements and constraints of your project, a jointer, or other tools
such as a table saw, router, or other hand tools, can be the best tool for your rabbeting needs. Always
consider safety when choosing a tool for rabbeting.
Performing a rabbet cut with this jointer may require the cutterhead guard removed. Promptly re-install
the guard after the rabbeting operation completes.
1. Inspect stock for quality issues before the
operation. The surfaces for rabbeting must
be flat and squared.
2. Set fence to 90°
3. Reposition the fence to set the width of a cut.
The amount of exposed cutterhead is the
width of the rabbet.
Please beware that the cutters are installed
in staggered formation, and the outermost
edge of the cutter is located near the edge of
the table. Make test cuts to confirm the
width of the cut as needed.
The fence travel is 10- 3/4” leaving
approximately 1- 1/4” as the minimum width
to rabbet. If the desired rabbet cut is less, an
auxiliary fence must be built and secured to
the jointer fence.
4. Remove the cutterhead guard as needed.
5. Start the jointer and dust collection system.
6. Place workpiece against the fence and
infeed-rabbeting table. Use push blocks
whenever permissible.
7. Follow steps [5- 9] in “Surface Planing” for
feeding stock through the jointer. Repeat
the process until reaching the desired depth
of the rabbet cut.
CAUTION: Beware that the rabbeting table is
short and narrow. Take extra caution and
support of the entire workpiece throughout
the operation.
8. Lower the infeed table gradually to remove
a portion of the material in each pass until
reaching the desired depth of cut. As much
as 1/8” of materials can be removed per pass.
CAUTION: For safety, never cut more than
1/8” per pass.
9. Disengage the infeed table depth stop when
t
he infeed table needs to go below 1/8”. This
jointer can produce a rabbet that is 3/4”
deep.
10. Reinstall cutterhead guard after the
rabbeting operation.
WARNING
If the cutterhead guard is removed for rabbeting operation, use extreme
caution when performing cuts. Reinstall the guard immediately when the
operation completes.
