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. Slow
down!

To cut dado with dado blades:
1. DISCONNECT MACHINE FROM POWER!
2. Adjust dado blade to desired depth of cut.
3.
Adjust distance between fence and inside
edge of blade (see Figure 62 on Page 41),
to dado length of a workpiece.
— If dadoing across workpiece, use miter
4.
Connect saw to power source.
5. Turn saw ON. Blade should run smoothly,
with no vibrations.
6.
When blade has reached full speed, perform
test cut with scrap piece of wood.
— If cut is satisfactory, repeat cut with actual
Cutting Dadoes with Standard Blade
A ripping blade (see Page 32) is typically the best
blade to use when cutting dadoes with a standard
blade because it efficiently removes sawdust.
To use standard saw blade to cut dadoes:
Fence
1.
DISCONNECT MACHINE FROM POWER!
2.
Mark width of dado cut on workpiece. Include
marks on edge of workpiece so cut path can
be aligned when workpiece is lying on table.

3.
Raise blade up to desired depth of cut (depth
of dado channel desired).

gauge and carefully line up desired cut
with dado blade. DO NOT use fence in
combination with miter gauge.
