Table Saw terminology

Arbor:

Metal shaft that connects the drive

mechanism to the blade.

Bevel Edge Cut:

Tilt of the saw arbor and blade

between 0° and 45° to perform an angled cutting
operation.

Blade Guard:

Mechanism mounted over the saw

blade to prevent accidental contact with the cutting
edge.

Crosscut:

Sawing operation in which the miter

gauge is used to cut across the grain of the
workpiece.

Dado Blade:

Blade(s) used for cutting grooves and

rabbets. A stacked dado set can be used for wider
grooves.

Dado Cut:

Flat bottomed groove in the face of the

workpiece made with a dado blade.

Featherboard:

Device used to keep a board

against the rip fence or table, allowing the operator
to keep hands away from saw blade.

Freehand:

Moving the workpiece into the blade

using only the hands, without a fixed positioning
device. (This is a dangerous, unacceptable
procedure on a table saw

– always use appropriate

devices to feed the workpiece through the saw
blade during cutting operations.)

Kerf:

The resulting cut or gap made by a saw

blade.

Kickback:

An event in which the workpiece is lifted

up  and  thrown  back  toward  an  operator,  caused
when  a  workpiece  binds  on  the  saw  blade  or
between  the  blade  and  rip  fence  (or  other  fixed
object).  To  minimize  or  prevent  injury  from
kickbacks, see the

Operations

section.

Miter Gauge:

A component that controls the

workpiece movement while performing a crosscut
of various angles.

Non-Through Cut:

A sawing operation that

requires  the  removal  of  the  blade  guard  and
standard  riving  knife,  resulting  in  a  cut  that  does
not  protrude  through  the  top  of  the  workpiece
(includes dado and rabbet cuts).

The  blade  guard  and  riving  knife  must  be  re-
installed  after  performing  a  non-through  cut  to
avoid accidental contact with the  saw blade during
operation.

Parallel:

Position of the rip fence equal in distance

at every point to the side face of the saw blade.

Perpendicular:

90° (right angle) intersection or

position of the vertical and horizontal planes such
as the position of the saw blade (vertical) to the
table surface (horizontal).

Push Board/Push Stick:

An instrument

usually of

wood or plastic, used to safely push the workpiece
through the cutting operation by keeping the
operator’s hands at a distance.

Rabbet:

A cutting operation that creates an

L-shaped channel along the edge of the board.

Rip Cut:

A cut made along the grain of the

workpiece.

Riving Knife:

A metal plate fixed relative to the

blade, which moves with the blade as cutting depth
is  adjusted.  Thus,  it  maintains  not  only  the  kerf
opening  in  the  workpiece,  but  also  the  knife-to-
blade  distance.  A

low-profile

riving knife sits lower

than the top edge of the blade, for making a non-
through cut.

Splitter (Spreader):

A stationary metal plate to

which the blade guard is attached that maintains
the kerf opening in the workpiece during a cutting
operation. (JET table saws use the superior Riving
Knife system instead.)

Standard Kerf:

1/8

” (3.175mm) gap made with a

standard blade.

Straightedge:

A tool used to check that a surface

is flat or parallel.

Through Sawing:

A sawing operation in which the

workpiece  thickness  is  completely  sawn  through.
Proper blade height  usually allows 1/8" (3.175mm)
of the top of blade to extend above the wood stock.
Keep  the  blade  guard  down,  the  anti-kickback
pawls  down,  and  the  riving  knife  in  place  over  the
blade.
