Circular Saw Blades for Wood

Advice Before you Buy a Saw Blade

The most useful and important aspect of a saw blade is, precisely, that you can change the saw blade to make various cuts in materials of various densities. To know how to buy a circular saw blade for wood, we’ll focus on the teeth of the blade.

Depending on the material being cut, these blades can be:

Large-toothed saw blades

This is the most typical cutting blades for wood; it cuts almost any type of wood, as long as the cut follows the direction of the wood’s grain. It’s a standard saw blade ideal for quick cuts, with more or less precision depending on the hardness of the piece to be cut.

Fine- or medium-toothed saw blades

Ideal to make more precise cuts in very hard wood or other hard materials like concrete. (To cut this type of material, many fine- or medium-toothed blades come with carbon- or diamond-tipped teeth, that makes them more steadfast and increases the precision of the cut.)

Ultra-fine-toothed saw blades

These are ideal for high-precision jobs where you need a smooth and clean cut, above all when working with hard materials or perpendicular to the grain of the wood.

However, the size of the blade’s teeth only determines how that blade will attack the wood it’s cutting straight on. We also have to take into account the angle of the teeth on the blade, and the variation within this angle.

  • Small fixed angle with a lot of variation: ideal to slice through soft wood in the direction of the grain.
  • Large fixed angle with little variation: small, very sharp teeth are ideal to cut very hard wood that offers a lot of resistance, because they reduce the friction caused by the cut.
  • Small fixed angle with little variation: to cut wood with high precision, and produce a smooth cut in soft wood, hard wood, or against the grain.
  • Large fixed angle with a lot of variation: ideal for quick cuts in large pieces of soft wood where the finished product is less relevant than the rapidity of the cut.

It’s important to also be aware that the diametre of the blade gives it stability, for which, when buying a saw blade, you should ensure that the blade isn’t so wide that it will produce a lot of vibration, and oscillate too much when it’s cutting.

Among the cheapest blade models for a circular saw, we can find very rustic options of blades for cutting wood, like SourcingMap or AmazingDeal, which come with a single blade to cut soft wood for as little as  3.60 $, or mini-blades kits with a vise at 4 $. These options are ideal for whomever wants to buy a cheap tool to solve an unexpected problem or do some short job.

On the other hand, blades from brands that offer high-quality blades with all the necessary characteristics for a clean cut in various materials, or in very hard materials, like Bosch, can exceed the prices of some machines! Among the most costly, we have the Expert blade from the above mentioned brand Bosch, at 200 $. However, the most costly models come from the brand Dewalt, and its series of carbon-tipped blades for cutting bamboo with high precision oscillates in price between 281 and 265 $.
