GLOSSARY OF TERMS

Non-Through Cuts

Any  cutting  operation  where  the  blade  does  not  extend 
completely through the thickness of the workpiece.

Push Blocks (for jointer planers)

Device used to feed the workpiece over the jointer planer 
cutterhead during any operation. This aid helps keep the 
operator's hands well away from the cutterhead.

Push Blocks and Push Sticks (for table saws)

Devices used to feed the workpiece through the saw blade 
during cutting operations. A push stick (not a push block) 
should be used for narrow ripping operations. These aids 
help keep the operator's hands well away from the blade.

Pilot Hole (drill presses)

A small hole drilled in a workpiece that serves as a guide for 
drilling large holes accurately.

Resaw

A cutting operation to reduce the thickness of the workpiece 
to make thinner pieces.

minute.

Ripping or Rip Cut

A cutting operation along the length of the workpiece.

Riving Knife/Spreader/Splitter (table saws)

A metal piece, slightly thinner than the blade, which helps 
keep the kerf open and also helps to prevent kickback.

Saw Blade Path

The area over, under, behind, or in front of the blade. As it 
applies to the workpiece, that area which will be or has been 
cut by the blade.

Set

The distance that the tip of the saw blade tooth is bent (or 
set) outward from the face of the blade.

Snipe (planers)

Depression  made  at  either  end  of  a  workpiece  by  cutter 
blades when the workpiece is not properly supported.

Through Sawing

Any cutting operation where the blade extends completely 
through the thickness of the workpiece.

Throw-Back

The throwing back of a workpiece usually caused by the 
workpiece  being  dropped  into  the  blade  or  being  placed 
inadvertently in contact with the blade.

Workpiece or Material

The item on which the operation is being done.

Worktable

Surface  where  the  workpiece  rests  while  performing  a  
cutting, drilling, planing, or sanding operation.

Anti-Kickback Pawls (radial arm and table saws)

A  devise  which,  when  properly  installed  and  maintained, 
is designed to stop the workpiece from being kicked back 
toward the front of the saw during a ripping operation.

Arbor

The shaft on which a blade or cutting tool is mounted.

Bevel Cut

A cutting operation made with the blade at any angle other 
than 90° to the table surface.

the end) is angled rather than at 90°.

Compound Cut

A cross cut made with both a miter and a bevel angle.

Crosscut

A cutting or shaping operation made across the grain or the 
width of the workpiece.

Cutter Head (planers and jointer planers)

A rotating cutterhead with adjustable blades or knives. The 
blades or knives remove material from the workpiece.

Dado Cut

A non-through cut which produces a square-sided notch or 
trough in the workpiece (requires a special blade).

Featherboard

A  device  used  to  help  control  the  workpiece  by  guiding 
it  securely  against  the  table  or  fence  during  any  ripping 
operation.

FPM or SPM

Feet per minute (or strokes per minute), used in reference 
to blade movement.

Freehand

Performing a cut without the workpiece being guided by a  
fence, miter gauge, or other aids.

throwing the workpiece back toward operator.
