Cutting Dadoes with a Dado Blade
Because dado blades are much wider than stan-
dard blades, they place a greater amount of force
against the workpiece when cutting. This addition-
al force increases the risk of kickback, requiring
the operator to take additional steps when cutting
to keep their injury risk at an acceptable level.
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 achieve
the desired cutting depth.
The Figure below demonstrates the sequential
process of making multiple, light cuts that get
progressively deeper. The actual number of cuts
used should be determined by workpiece hard-
ness, total dado depth, and feed rate. In general, if
you hear the motor slow down during the cut, you
are cutting too deep or feeding too fast.

Cutting Dadoes with a Standard
Blade
A ripping blade is typically the best blade to use
for cutting dadoes when using a standard blade
because it removes sawdust very efficiently. See
Page 37 for blade details.
To use a standard saw blade to cut dadoes:
1.
DISCONNECT SAW FROM POWER!
2.
Mark the width of the dado cut on the
workpiece. Include marks on the edge of the
workpiece so the cut path can be aligned
when the workpiece is lying on the table.
3.
Raise the blade up to the desired depth of cut
(depth of dado channel desired).
4.
Set the saw up for the type of cut you need
to make, depending on if it is a rip cut (Page
37) or crosscut (Page 39).
5.
Align the blade to cut one of the dado sides,
as shown in Figure 64.
