ANTI-KICKBACK PAWLS – Prevents the workpiece

from being kicked upward or back toward the front of the

table saw by the spinning blade.
ARBOR – The shaft on which the blade or dado is

mounted.
BEVEL CUT – An angle cut made through the face of

the workpiece.
BLADE BEVEL SCALE – Measures the angle the blade

is tilted when set for a bevel cut.
BLADE ELEVATION AND TILTING HANDWHEEL –

Raises and lowers the blade or tilts the blade to angle

between 0

and 45

for bevel cuts.

BLADE GUARD – Clear plastic cover that positions

itself over the blade while cutting.
COMPOUND CUT – A simultaneous bevel and miter

cut.
CROSSCUT – A cut made across the width of the

workpiece.
DADO – Special cutting blades that are used to cut

grooves in a workpiece.
FEATHERBOARD – When ripping a workpiece on your

table saw, this keeps it ﬁrmly and safely against the

rip fence. It also helps prevent chatter, gouging, and

dangerous kickback.
FREEHAND – Performing a cut without using a rip

fence, miter gauge, hold down or other proper device to

prevent the workpiece from twisting during the cutting

operation.
GUM – A sticky sap from wood products.
HEEL – Misalignment of the blade.
JAMB NUT – Nut used to lock another nut in place on a

threaded rod or bolt.
KERF – The amount of material removed by the blade

cut.
KICKBACK – Occurs when the saw blade binds in the

cut and violently thrusts the workpiece back toward the

operator.
MITER CUT – An angle cut made across the width of

the workpiece.
MITER GAUGE – A guide used for crosscutting

operations that slides in the table top channels (grooves)

located on either side of the blade. It helps make

accurate straight or angle crosscuts.

NON-THROUGH SAWING - refers to any cut that does

not completely cut through the workpiece.
OVERLOAD RESET SWITCH – Protects the motor if it

overloads during operation, provides a way to restart the

saw.
PUSH STICK – Used to push workpieces when

performing ripping operations.
PUSH BLOCK – Used for ripping operation when the

workpiece is too narrow to use a push stick. Always use a

push block for rip widths less than 2 in (50.8 mm).
RESAWING - ﬂipping material to make a cut the saw is

not capable of making in one pass.

Resawing IS NOT recommended.
REVOLUTIONS PER MINUTE (RPM) – The number of

turns completed by a spinning object in one minute.
RIP FENCE – A guide used for rip cutting which allows

the workpiece to cut straight.
RIPPING – Cutting with the grain of the wood or along

the length of the workpiece.
RIVING KNIFE – A metal piece of the guard assembly

located behind and moves with the blade. Slightly

thinner than the saw blade, it helps keep the kerf open

and prevents kickback.
SAW BLADE PATH – The area of the workpiece or

table top directly in line with the travel of the blade or the

part of the workpiece that will be cut.
SET – The distance between two saw blade tips, bent

outward in opposite directions to each other. The further

apart the tips are, the greater the set.
TABLE INSERT – Insert that is removed from the table

to install / remove blades. When dado cutting, a dado

insert plate must be used.
THROUGH SAWING – Making a cut completely

through the length or width of a workpiece.
