Wood Cutting Band Saw Blade – How to choose a band saw blade for wood

Wood cutting band saw blade

In this article, we at Amacut are going to explain something about the wood cutting band saw blade and how to choose a band saw blade for wood.

The wood band saw blade is one of the most powerful and strong blades, which is used to cut all types of timber and hardwoods. The wood saw blade is also called bimetallic saw blade and is suitable for cases such as cutting soft and hard wood, separating bark and cutting thick tree trunks. This type of blade has very good flexibility when cutting and its teeth are made of the highest quality European steel.

How to choose a band saw blade for wood

When it comes to bandsaw blade design for sawing hardwood, there are probably as many opinions as there are bandsaw manufacturers. So let’s look at some basic bandsaw blade ideas and concepts to understand what factors are critical to our performance and therefore what designs might be best.

The first step in choosing a woodworking bandsaw blade is to define the cutting requirements. Some considerations are related to the quality of the cut – smoothness, accuracy or flatness, and radius of curvature – and some to the wood itself – wood density (or hardness, which is related), depth of cut (or thickness of material).. and grain direction ( intersection). We don’t believe that cutting speed should be an issue, but some people are concerned about speed.

The width of the wood cutting band saw blade

The width of a blade is measured from the top of the tooth to the back edge of the blade. Wider blades are generally stiffer and track better on band wheels than narrow blades. When cutting thicker material, a wider blade has less ability to deflect because the back end helps guide the front of the blade when cutting, especially if the side clearance is not excessive.
Special Note: When resawning a piece of wood (ie, cutting it into two pieces the same thickness as the original piece), a narrower blade will actually cut smoother than a wider blade. The cutting force causes a wide blade to deflect sideways, while with a narrow blade the force pushes it back, but not sideways. This is not what one would expect, but it is actually true.
When sawing hardwoods and high-density softwoods such as southern yellow pine, we prefer to use as wide a blade as possible. For wood with low density, if you wish, you can use a narrower wood band saw blade.

The thickness of the band saw blade

In general, the thicker the blade, the more tension can be applied. Thicker blades are also wider blades. More stretch means smoother cuts. However, thicker blades mean more sawdust. Thicker blades are also more difficult to bend around band wheels, so most band saw manufacturers specify thickness or thickness ranges. Band wheels with a smaller diameter require thinner blades.
In general, thicker and wider blades are chosen when sawing dense woods and woods with tight knots. Such wood requires the additional strength of a thicker and wider blade to prevent breakage. Thicker blades also deflect less when resawing.

Can you make the most cuts with one blade?

Every time you change from band saw blade width to band saw blade width, you must reset the tracking, tension, and saw blade guides. This process can take 15 to 30 minutes depending on your saw. So we understand that you might not want to do this most of the time. This is why many people use a 40- or 50-tooth compound blade for all cuts on their table saw, or use the same speed setting for all their drill press bits. We get it, these changes are hard.
