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 along the edge of a workpiece with a dado
blade requires a sacrificial fence (see Figure.44). 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 and rabbet width
needed.
When using a dado blade, the included dado table insert
must be installed and used during rabbeting operations.
Cutting.Rabbets.with.a.Dado.Blade
1. DISCONNECT MACHINE FROM POWER!
2. Lower dado blade all the way down.
3. Secure sacrificial fence with clamps to fence.
Note: Be sure to allow adequate clearance below
clamps for workpiece to travel freely.
4. Position fence so dado blade protrudes beyond fence
the same amount as desired width of rabbet (see
Figure.45).
5. Mark a reference line on the face of the sacrificial
fence indicating approximate rabbet depth.
6. Secure fence, reconnect machine to power, and turn
machine ON.
7. Slowly raise dado blade into sacrificial fence until it
reaches line marked previously on sacrificial fence.
8. Perform test cut on a scrap piece of wood to verify
rabbet height and width.
— If cut is satisfactory, repeat cut with workpiece.
Dado. blades. have. a. higher. risk. of.
kickback. than. normal. blades. because.
their.larger.size.applies.stronger.forces.
to. the. workpiece.. This. risk. increases.
relative.to.the.depth.and.width.of.the.
cut.. To. minimize. your. risk. of. serious.
personal. injury,. ensure. that. stock. is.
flat. and. straight,. and. make. multiple.
light.cuts.(rather.than.one.deep.cut).to.
