fordrillinglargeholesaccuratelyorforinsertionofascroll
sawblade.
Push Blocks (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 (table saws)
Devicesusedtofeedtheworkpiecethroughthesawblade
duringcuttingoperations.Whenmakinganarrowripcut
withoutajigorsimilarcuttingaid,alwaysuseapushstick
(notapushblock).Apushblockcanbeusedfornarrow
rippingoperations,ifa jig orsimilarcuttingaid is used.
Theseaidshelpkeeptheoperator’shandswellawayfrom
theblade.
Rabbet
Anon-throughcut positioned on the endoredgeofthe
workpiecewhichproducesasquare,two-sidednotchor
troughintheworkpiece.
Resaw (table saws and band saws)
Acuttingoperationtoreducethethicknessoftheworkpiece
tomakethinnerpieces.
Resin
Asticky,sap-basedsubstancethathashardened.
Revolutions Per Minute (RPM)
Thenumberofturnscompletedbyaspinningobjectinone
minute.
Ripping or Rip Cut (table saws)
Acuttingoperationalongthelengthoftheworkpieceand
typicallyinthedirectionofthegrain.
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.
Snipe (planers)
Depressionmade at either endofaworkpiece by cutter
bladeswhentheworkpieceisnotproperlysupported.
Taper Cut
Acutwherethematerialbeingcuthasadifferentwidthat
thebeginningofthecutfromtheend.
Through Sawing
Anycuttingoperationwherethebladeextendscompletely
throughthethicknessoftheworkpiece.Thistypeofcutwill
separateasingleworkpieceintotwopieces.
Workpiece or Material
Theitemonwhichtheoperationisbeingdone.
Worktable
Surfacewheretheworkpiecerestswhileperformingacut-
ting,drilling,planing,orsandingoperation.
Anti-Kickback Pawls (radial arm and table saws)
Adevice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.
Chamfer
Acutremovingawedgefromablocksotheend(orpartof
theend)isangledratherthanat90°.
Compound Cut
Acrosscutmadewithbothamiterandabevelangle.
Cross Cut
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 (table saws and compound sliding miter saws)
Anon-throughcutwhichproducesasquare,three-sided
notchortroughintheworkpiece.
Featherboard (table saws)
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fence,orotheraids.
Gum
Asticky,sap-basedresiduefromwoodproducts.
Heel
Alignmentofthebladetothemitergaugegroove.
Kerf
Thematerialremovedbythebladeinathroughcutorthe
slotproducedbythebladeinanon-throughorpartialcut.
Kickback
Ahazard that canoccurwhenthe blade bindsorstalls,
throwingtheworkpieceinthedirectionofthespinningblade.
Miter Cut
Acuttingoperationmadewiththeworkpieceatanyangle
tothebladeotherthan90°.
Non-Through Cuts (table saws and compound sliding
miter saws)
Anycuttingoperationwherethebladedoesnotextendcom-
pletelythroughthethicknessoftheworkpiece.Thisisacut
wherethebladewillnotcuttheworkpieceintotwopieces.
