Best Circular Saw Blades for 2020

The circular saw blade is to the cutter as scissors are to the barber.
Harmony between the respective pairs are essential to create masterpieces.
And much like the drill bit, the blade is the only part that actually comes into contact with the material thus has to be well crafted, solid, precise and deliver clean results.
Choosing the appropriate blade is rather important!

The Blade Explained

The type of work to be performed and the usage frequency are key in determining the type of blade you need.
For finer cutting, a blade with more smaller teeth is deployed as opposed to a blade with fewer, larger teeth where output volume over finesse is required.
Here are the core features of the blade:

Two core factors will effect the type of finishblade diameter and number of teeth on the blade.
Indeed, power driven by the unit can determine your output however it’s the blade itself which comes into contact with the material. Ultimately, control of the tool needs synergy with the blade. 
The depth of the cut will be closely related to the diameter of the blade. For example, a cutting depth of 3 inches will require a blade of diameter of 8 ¼ inches. You will also have to consider the thickness of the material to be treated. Regarding the teeth, they can be flat, trapezoidal or bevel. 

Consider the following before purchasing a saw blade.

  • The finish of the material cut will be affected by the blade tooth and number of teeth.
  • What type of cut you’ll be doing.
  • Does your saw house the blade you need? Check the bore size and maximum cutting depth of the saw.
  • The RPM is important. This must be relative to the diameter of the blade. Heat will cause blades will expand under continuous exposure to the material.

Blade Replacement

This is usually a common-sensical decision.
If the blade is visibly cracked, teeth damaged or rusted poor finishing will result, as well as a an unsafe tool to operate.
Occasionally it can be harder to spot less obvious things such as partially worn or rounded teeth or a bowed blade especially when its all too easy to remove the saw from the shelf, fire it up and cut away.  
For cut and thrust work such as bulk lumber chops the need for a totally clean cur may lead to complacency but its important to inspect the finishes every so often for consistency. A dull blade results in poor efficiently and takes longer to complete the job.

Teeth

The number of teeth the blade has will determine the finish and cutting rate.
The more teeth, the better the cutting finish the slower the cutting process.
Fewer teeth are generally deployed for bulk carpentry – quick timber cuts. These are more efficient but less refined.

More teeth = better finish = slower rate

Less teeth = quicker rate = less refined finish

Bore, RPM & Depth of Cut

Bore
The bore is the hole in the middle of the blade.
Generally you will purchase a blade with a bore to match the saw it fits however you may need a blade with a bore larger than the saw. For this you will need a reduction ring.
These fit blades whose bore is larger than the shaft of the saw.
It’ important to note the reduction ring must not be thicker than the blade.
And must have a diameter at least 10mm smaller than the clamping flange for secure fitting.

RPM

The larger the blade the lower the RPM
The smaller the blade the higher the RPM

Depth of cut

Larger blades = higher depth of cut
These come in standard 7.25″ for a 2.5″ depth of cut and 8.25″ for a 3.0″ depth of cut

Blade Materials

As I have stated over a number of articles, the blade is the only part that comes into contact with the material and that part should be appropriate for the material it comes into contact with.
Bordering Dr. Seuss territory with that one.

The table below gives a quick guide to applications and the correct blade to use.

In fact, your blade you choose must be a consequence of the task you’ll be performing with it. Remember, there is no favorable wind for that who doesn’t know where to go
