Hey there, Im Carmen, and today on Gear up with Greggs were going to be taking these
Irwin Saw blades for a trial run.
Now, before we start demonstrating these Irwin Sawblades
I want to get some basic terminology out of the way.
First up, ripcut and crosscut.
The short version is that a ripcut changes the width of the material
and a crosscut changes the length.
A crosscut, the type of cut youll use most often, is when you cut across the grain of the wood.
Like cutting a 2 x 4 in half!
A rip cut would be used to cut with the grain of the wood,
like when you trim plywood into narrower widths.
But what exactly do we mean by grain?
Well, wood grain or wood fibers run the length of the lumber.
Think of the wood fibers as a bundle of straws.
A crosscut, or cut across the grain, makes those straws shorter.
A ripcut is when you cut with the grain of the wood, making the bundle of straws narrower.
Saw blades are specifically made to be better at certain types of cuts, so we are going
to show you what features to look out for in a saw blade and how that translates to
the types of cuts it will make.
Now, the number of teeth actually determines your blades cutting action.
More teeth mean a slower and smoother cut, which is something you want in a crosscut.
Youll notice that more teeth on a blade will decrease the hook angle,
which is the angle of the tooth relative to the center line of the blade.
This is because these blades are for super crisp, slow, methodical cuts;
like cutting finishing trim pieces on a table saw.
With very little space between the teeth, you can feed the material at your own pace
and the saw wont pull or tug.
On the other hand, if you are not concerned about an impossibly smooth cut,
fewer teeth will do the trick!
Ripping blades have fewer teeth and an extremely positive hook angle.
The higher the positive hook angle, the more aggressive the blade,
this means it will pull material and get the job done faster.
Another feature you will notice on these blades is the large spaces between the teeth.
These are called gullets, and they are used to remove sawdust and any other waste material
that the blade encounters from the cut.
Basically, a larger gullet equals more material removed per slice.
Now, when you get into more expensive blades, youre going to start to notice more holes!
Well, these larger holes closer to the center of the blade are called vents or body slots.
They help to reduce vibration and heat
and these smaller cutouts in the gullet are called expansion slots.
When the blade gets hot from constant use, the expansion slots allow the blade room to
grow instead of warping when it doesnt have room to expand.
This causes less vibration, a straighter cut,
and helps to maintain the strength of the blade over time.
But the coolest thing about these little slots is what they're modelled after!
The similarly shaped holes found in t rex teeth!
As you can see, here at Greggs, we carry a large selection of Irwins Saw Blades.
First up, weve got our Cordless Circular Saw Blades.
These blades are optimized specifically for cordless circular saws based on their size.
The cuts made by this blade are ultrathin because of the thin blade Kerf.
Kerf is the term for the width of the carbide teeth on a blade.
A thin kerf means the saw doesnt have to work as hard to get through the material and that
means we get more cuts throughout the battery life of our cordless circular saws.
Even better, those super sharp carbide teeth ensure that this blade has a long lifespan.
Another feature of these awesome blades is this dip behind each tooth.
This is referred to as a reinforced shoulder, which means the part of the blade behind each
tooth will spend less time in contact with your material, reducing the chance of kickback
and translating to longer life for the blade.
Now, we have different options, depending on the kind of cut you need.
For quick, dirty cuts we have multiple sizes of 18 teeth blades,
and for silky smooth finishingcuts, you can pick up a 40 tooth blade in the 6 1/2 inch size.
Next up we have our Classic Series Circular Saw Blades.
These blades feature an economical grade of carbide teeth brazed to a stainless steel body,
built to save you money.
These wont last the longest out of the Irwin blades, but they are not meant to!
These are the blades are built for your abusive jobs, like sawing wood beams encrusted in concrete.
One of our most popular blades available from Irwin is the Marathon Circular Saw Blades.
These come in a standard size of 7 1/4 inches but with 24
or 40 teeth depending on the type of cuts you want.
Some interesting features of these blades include these heat vents and expansion slots,
which are optimized to reduce the vibration and give you a straighter cut every time.
Another feature is the reinforced shoulder, remember?
The little dip behind each tooth!
Last, well, its hard to see with your naked eye, but every other tooth on this blade is 0.1mm thinner.
You wouldnt think that this amounts to much, but it actually translating into cuts that are 20% faster!
Now well move onto our Miter or Table Saw Blades.
These are a great addition to any precision project.
The blades are designed with a smooth finish in mind as the teeth are 400 grit diamond ground
just the thing to make your cut as clean and accurate as possible.
The smaller blades with less teeth are your quick cut ripping blades, but as we move up
in the line we see just how many teeth we can fit on these large blades
and how narrow of a hook angle it will get!
These blades are definitely for your precision work, like final trim pieces.
Expertly balanced with construction grade carbide teeth, this blade is sure to last
a long time.
Finally we've got the Marathon with WELDTEC Circular Saw Blades.
These ones look pretty heavy duty, but thats because they're built for the Big Jobs.
This revolutionary new saw blade has welded carbide teeth for a 30% stronger tooth bond
and a longer life.
These teeth are sharpened to fine, more durable cutting edges that stay sharp, longer.
And remember those vents we talked about before?
Well, this blade is full of them to dissipate heat, a sure sign of a long lasting and high quality blade.
Even this board filled with nails is no match for the WELDTEC saw blade!
So, keep in mind that no matter what you need, Greggs has the bite to find the right blade for the job.
