Rabbet.Cutting
Commonly used in furniture joinery, a rabbet cut is
an L-shaped groove cut in the edge of the workpiece.
Rabbets can be cut with either a dado blade or a standard
saw blade.
Rabbet cutting on the edge of the workpiece with a dado
blade requires a sacrificial fence (see Figure.88). Make
the sacrificial fence the same length as the fence and
⁄
" thick. Attach it to the fence with screws or clamps,

making sure they are all secure and tight. Raise the blade
into the sacrificial fence to the height needed.
When installing the dado blade, remove the special arbor
washer (part #349 in parts breakdown) to allow room for
the blade. A blade flange MUST always be between the
blade and the arbor nut. Refer to the machine data sheet
for the maximum width of dado that this saw can cut.
Cutting.Rabbets.with.a.Dado.Blade
1. DISCONNECT SAW FROM POWER!
2. Adjust the dado blade to the height needed for the
rabbeting operation. When cutting deep rabbets,
take multiple light passes to reduce the risk of kick-
back.
3. Adjust the fence and align the workpiece to perform
the cutting operation, as shown in Figure.89.
4. Reconnect the saw to the power source and turn
the saw ON. When the blade has reached full speed,
perform a test cut with a scrap piece of wood.
— If the cut is satisfactory, repeat the cut with the
final workpiece.
