The Magic of Spiral Router Bits

Video Review


Video Transcript


g’day I’m Patrick from douglas-fir
design welcome to the router bits
so here in front of me I have some
spiral up cuts so the spiral down cuts
and just a standard straight bit for
comparison now these spiral cut bits
perform a similar function in many ways
to your standard straight cut bits but
they’re significantly more expensive and
so you might wonder why would I be
spending a whole lot more money for a
bit that does kind of a similar job
although they do essentially the same
thing as a straight cut there are some
areas where they really excel and will
give you results that you just can’t
achieve with a straight cut and for many
applications that’s well worth the money
that you need to spend to get these
exceptional little bits so in
understanding why a spiral bit even
exists I find it helpful to think about
the vague evolution of a router bit the
the most common straight bits have two
blades that run straight up and down
directly perpendicular to the shank and
they do a good job but each blade every
time that comes in contact with the wood
is hitting the whole face of the blade
against that piece of wood in one little
whack just does it over and over again
in order to make those cuts smoother
router bit manufacturers have started
putting these blades on a slight angle
which means instead of the blades
hitting the timber at one time they
start to slice through from the top to
the bottom in this case and that allows
you for us to have a smoother cut and it
allows the motor to work a little bit
less hard because you’re not just
something through the wood in each pass
spiral router bits take that concept one
step further by angling the blade on a
much steeper angle until it’s almost
just like a drill bit and so the cutting
motion isn’t in one something chisel
blade hitting the timber at each time
it’s a tiny fraction of the blade as it
curves around spiraling through the
timber so because you have a spiral
blade it means that there’s actually
constantly a piece of the blade in
contact with the timber you don’t have
what you have with these standard are
straight bits we have blade contact
they’re numb for a half a rotation then
blade contact when you’re using one of
these bins especially with a really hard
timber and you’re trying to cut out a
lot
material you can give what most people
call shadow so it’s basically the motion
caused by each blade
thumping into the wood one after the
other cons you have constant blade
contact with these you’re actually
getting a slicing motion rather than
that thumping motion and you
dramatically reduce that chatter which
gives you a much smoother cut and it
means the motor at free me router is
working way less hot okay so there’s a
couple more benefits to spiral bits and
this applies to both up cut and down cut
I’ll explain the difference between
those in a second because they’re
essentially like a drill bit they’re
solid carbide and they have blade right
across the ends tip on both the up cuts
and down down cuts bits they they plunge
really well you don’t have the issue
that you might get with a straight bit
we’ve got that flat piece of non cutting
stock in the center there and that’s
gonna stop you plunging all the way down
these got these guys just don’t have
that problem and allows you to do really
deep plunges really easily one of the
other features because you have
continuous blade contact and just a much
longer blade surface these bits stay way
cooler and that means they’re gonna say
sharper for longer it also means you’re
not going to get burn marks in the
timber which can be really hard to
remove
and also just unsightly smoky unpleasant
in general so less heat less smoke less
burn marks in the timber so another
application where these guys really
excel is if you’ve got really difficult
or highly figured timber so the reason
that these do a better job is because
you’re not slamming into the wood with
each blade which has the tendency to
cause large chips and can tear out
little pockets of are nicely figured
bill you’ve got a continuous slicing
motion here which actually will slice
past those difficult bits of really
figured timber and will prevent them
from tearing out so you can get much
nicer results on on tricky wood that you
really want to maintain the integrity of
that surface
so the last feature which applies to
both up and down cut bits that I want to
talk about is basically the direction of
the cut so the effect that this has is
where the chips are going to go and
which edge of your cut is going to be
really nice and clean if you’re looking
at a straight cut yet as I said you just
got blades hitting the timber square the
the chips are just going to accumulate
in this area there’s no real reason for
them to go out the top except for just
general pressure and buildup of crud
inside the router bit so you can if
you’re doing really deep cuts into
timber if you if you have managed to
plunge down you can accumulate our chips
in there really easily with these spiral
bits they have a direction like a drill
bit and when you’re using a drill bit
the the chips move up the shank and come
out the top of the hole so a spiral down
cut bit also cuts directionally but it’s
kind of cutting in the opposite
direction it’s actually going to be
pushing the chips downwards and that can
have a benefit to some applications but
it’s not going to be for plunging
because with the spiral bits the blades
are actually hitting the timber on an
angle that’s what’s causing the chips to
go up or down in each case but that’s
also what causes one of the really cool
benefits of these bits is that the
blades as well as cutting the timber
across across the face it’s also cutting
down from either the top or the bottom
depending which one you’re using and
that means that you’re actually getting
a really smooth razor-sharp edge on one
of the surfaces either the top or the
bottom depending on which bit you’re
using now that can be really important
if you’re using veneers which have a
tendency to lift and chip or if you’re
using mallum iron which is also kind of
has a tendency to shatter and chip away
now even if you’re just using a really
nice timber like if you’re doing the top
of a table and you really want that edge
to be just razor sharp then these will
give you a much better by then you might
get with a straight
I want to walk through some of the more
specific uses for each of these just so
you can understand where you might use
an uppercut versus a Down cut and also
the advantage of being able to have
these bits with the bearings which is a
unique feature to these torque harder
bits there aren’t very many spiral bits
available at all with bearings and so it
is really handy and it opens up some
other possibilities so I want to start
by talking about some specific
applications of spiral up cut bits now
as we said before with an upper cut bit
the chips are coming back at you when
you’re using a handheld router so what
that means is that you have very good
chip ejection if you’re doing a deep cut
those chips are just going to keep
flying out if you’ve got a vacuum
attached to the router it’s gonna suck
them out really cleanly you’re not gonna
have a lot of stuff building up in the
hole that means you can do quite fast
cuts one of the things to consider
though is if this is cutting through the
timber and you’ve got your chips flying
out at high speed it also has a tendency
to slightly feather those edges now the
top edge sorry of if you’re cutting a
trench for instance or a little channel
in a nice good quality solid hardwood
that usually won’t cause any terror but
it is something to keep in mind one
thing I have done before is put just a
really thin layer of something like
packing tape over the place where I’m
going to be cutting that trench and that
prevents any terror and it works really
well so because this is acting kind of
like a drill it’s actually going to hold
your handheld router into the piece of
wood and conversely if you’re using this
in a table router it’s going to hold the
piece of wood down onto the table now
that can help stabilize things in some
ways it’s going to stop the router
jumping around one byproduct of that is
if you’re cutting a little trench the
bottom edge of the channel on a spiral
up cut bit is going to be really nice
and clean because these are acting
essentially like a drill bit they also
allow you to do really nice clean
mortises in ways that you just can’t
quite do with a standard straight bit
because this end
it’s exactly like a drill bit you can
plunge in as deep as you want now
ideally you probably wouldn’t want to
plunge in a full 50 mil and try and more
to sout that whole section in one go
it’s just provide too much pressure on
the on the bit and mainly on your
machine but you can still plunge in and
do a few passes without having to do
that sort of like floating clones which
you have to do with a standard straight
bit so really nice mortises excellent
chip ejection if you’re creating a nice
narrow mortise you’re not going to get
clogged up with crud in the hole it’s
all we’re going to come out the top and
get sucked away by your vacuum cleaner
so those are some really good
applications for these spiral up cut
bits if you’re not cutting a trench but
you’re actually trying to trim the edge
of a piece of timber then you’re going
to have access to a really nice clean
edge on the bottom face on the face
furthest away from the motor either in a
handheld or in a table and so when that
might be really useful is if you have
unknown a stool where you want the top
edge to be really nice and sharp and you
want to run that around on your on your
table router then that top edge is
what’s going to have a really nice clean
edge with no terror because the chips
and the timber is being pulled down into
the table now the inverse is true when
you’re using a handheld router you’d
want to keep the good face down so that
the cutting action would be pulling the
timber up and actually be creating a
really nice face on me on the underside
now
torque oughtta also makes these spiral
up cuts with a bottom bearing and so
that would allow you to do sort of a
pattern following application say you
created a a interesting shape and you
cut that out in your bandsaw and smooth
it off with a sander or however you want
and you can put that on the bottom place
your secondary piece on top and use that
bottom one as a guide to follow that
pattern and duplicate it as many times
as you want
now if you’re using an up cut bit then
the bottom side of the piece you’re
working on is going to be the good face
so just keep that in mind and that’s
really important if you’re trying to do
it in Mela mine or like a nice veneer or
apply or something so the final thing
that
these guys do really well and this kind
of applies to the are cut and the down
cut because if you are following a
pattern around you know and it’s maybe a
circle or something where you’re going
to have access to some grain where
you’re going to be cutting against the
grain which has a tendency for high tear
out these because they’re not
comfortably it isn’t hitting the grain
in a way that wants to pull it away it’s
actually slicing through it you it
allows you to do more complex shapes
than you could do with a standard
straight bit without flipping the timber
over and trying to follow that ground in
the direction that it wants to go so
you’ll always need to experiment to get
the best effect and also I found that
these get this as with all the router
bits these get the smoothest finish when
you cut cutting off as less less
material as possible so if you can trim
it up with a bandsaw first get it pretty
close to that line and then just cut off
a mill or two with these they work
beautifully I have pushed them through
the full width of the blade to do full
trenches or like full depth cuts in
timber and they work fine but I’ve
wanted to go back over them to clean up
those cuts a little bit just to get the
really glassy edge that these guys can
achieve a down cut bit is actually going
to be pushing the timber away from the
motor unlike an up cut bit which is kind
of pulling it towards it like a drill
bit so the reason that that can be
really beneficial is it allows you to
run along the face that you really want
to protect especially in veneers and
male’ mines and composite Timbers like
that and you’re actually pushing the cut
part of that edge which means you get a
really nice sharp edge even in cutting
up Frost veneers which have a tendency
to lift and splinter
so you’re never going to be damaging
that top edge as you’re cutting so
applications where this might be really
useful is cutting a rebate or a trench
or a little channel in some really nice
veneer or melamine or some other kind of
material like that which has a tendency
to be damaged easily but what you have
to keep in mind is because these are
pushing the timber downwards and that’s
what’s creating that really nice smooth
edge it’s also pushing the chips down
into the trough
so you can’t do really nice deep cuts
like you can with a spiral up cut bit
with a down cut bit you’re doing
multiple passes you’re getting a really
nice crystal clear edge on the top but
you are pushing those chips down into
the trough which just means you’re gonna
have to slow down a little bit you can
use these down cut bits for full depth
cuts through timber because the chips
are going to have some place to go
they’re going to be shooting away from
the motor rather than back up you can
also use it to do really nice clean edge
cuts and edge trims along timber and
melamine and fire and of course their
chips are going to be going away from
the motor so if you’re using a handheld
router that means it’s going to be
pushing the chips down towards the floor
and if you’re using this in a table
router it means the chips are going to
be going upwards which you might want to
put a guard in place so they’re not just
flying into your face another thing to
keep in mind when you’re using these
even though they can give you that
really nice clean edge because rather
than pulling timber into the motor it’s
actually pushing it away slightly you
want to make sure you have really good
guides in place so that you are getting
the benefits of these bits without it
trying to jiggle away and move away from
the timber so it’s just a matter of
working slowly and smoothly to get those
really nice clean edges that you’re
looking for which you kind of can’t
really achieve in a lot of cases
especially with something like melamine
with a straight view with a standard
straight bit I hope that has helped kind
of demystify some of the uses and the
reasons that you would want to purchase
a handful of these spiral bits you’ve
got fantastic smooth cuts especially in
figured wood with way less chatter than
you would have with a standard straight
bit you have access to really clean
edges on the top or the bottom depending
on if you’re going to be using an up cut
or a down cut you’ve got the ability to
do deep plunges with an upper cut as
well as create really nice clean troughs
with a Down cut and in the torkado range
you do have access to these follow the
pattern following bearings which as far
as I know and not not a lot
but the companies or have actually
managed to do yet this spiral it’s so
useful I’ve been using them far more
than I thought I would and they’ve
definitely earned the money that I spent
on them initially because they just do
such great work and create really good
results you can pick these up from tim
makan they’re made by torte Carter and
you can grab them on the timber Khan
website at timber con-com W or in either
of their stores in Perth and in
Melbourne
