Choosing Band Saw Blade

Your Guide to Band Saw Blades

Band saw blades are so unique that just the smallest difference in the blade can have such a dramatic difference from the last. Due to this dramatic difference, you should be fully aware of your desired cut and project at hand before deciding on a blade.

Each blade works best with different materials and cuts, so it’s crucial to know your band saw blade types before operating this power tool. Before selecting a blade, here are some questions you should be able to answer:

  • What is the composition of the material?
  • Is there any bundling of the material?
  • Will it be a cooled cut?
  • What machine are you performing the cut with?
  • What is the shape of the part to be cut?

How to Choose Your Band Saw Blade Types

Band saw blade guides will tell you there are three main areas to consider before selecting the best band saw blades, these include:

What Type of Band Saw Are You Working With?

The type of band saw you’re using should be your first consideration, particularly whether it’s for metal or wood.

For metal band saw blades, select a carbon tool steel or bimetal blade to perform the smoothest cut. The cheaper alternative is a carbon steel blade, ideal for projects at home but with a shorter shelf life.

The bimetal blades will last 10 times longer but are a lot more costly. Depending on how often you use it, whether at home or larger scale production, you might choose to go with the cheaper or more expensive metal band saw blades.

For woodworking band saw blades, carbon steel is a great choice. It’s going to last a lot longer performing cuts on wood rather than with metal, so it’s okay to select the cheaper option. For something a little tougher, you could also work with premium gold carbide, a favourite choice for woodworking band saw blades.

Choosing Band Saw Blades

How Tight do You Need to Turn?

This factor will depend on the type of machine you’re working with, horizontal or vertical. Your horizontal band saw blades only ever use one width of blade, as this is what they’re designed to do.

Vertical band saws are entirely different altogether and vary greatly in their length. Be sure to check the minimum turning diameter for each blade before deciding if it’s right for your project.

What do You Intend to Cut?

The material you’re cutting and type of cut you want to perform will determine the tooth pattern that’s required. For both metal cutting and wood cutting, there are different ways to perform a cut.

Choosing Band Saw Blades

Woodworking band saw blades work on the theory that the fewer teeth you have per inch, the rougher and faster you’ll cut. Whereas, the more teeth you have the smoother and slower you’ll cut. However, every project is different and it will depend on the type of wood you’re working with as well.

Metal cutting band saws go by the thickness of material to determine their tooth pattern. For thin materials, you should select a blade that has more teeth per inch. Thick materials need a blade that has fewer teeth per inch to perform a deeper cut.

Number of Teeth Per Inch

Those who work with band saws will understand the importance of teeth per inch when deciding on the desired finish and feed rate of your workpiece.

For resawing wood and cutting thicker stock, a coarse tooth blade should be used, generally 2 or 3 teeth per inch. If you’re working with thin metals and plastics under a quarter inch, go with a fine toothed blade of 18 to 32 teeth per inch.

For general woodworking, roughly 4 teeth per inch will give you a fast and rough cut, but something closer to 14 teeth per inch will make a slow and smooth cut.

Band Saw Blade Teeth per Inch

Some general things to remember when selecting your teeth per inch for band saw blade types:

  • At least three teeth per inch should remain in the workpiece;
  • The more teeth per inch you have, the smoother your cut will be and the slower it will take to perform;
  • The fewer teeth per inch, the faster and rougher cut you’ll receive;

Changing A Band Saw Blade

Band saw blades need to be properly maintained to ensure a long life, but even the best cared for blades require changing from time to time. Blades can crack, become worn down, or even lose some of their teeth, but with our simple guide you’ll be able to change your band saw blade with minimal fuss and optimum safety so you can continue on with your work.

Choosing Band Saw Blades

Ready the New Blade

Many band saw blades come packaged in a tight coil, so you’ll need to have the blade ready well before you decide to change it. Wearing protective gear for your hands and eyes, hold the blade together and cut the ties. Throw the blade clear from you to allow it to unravel.

Prepare Your Saw

Now that the blade is ready to go, you’ll have to turn off your band saw completely and disconnect it from its power source so that you can prepare it for its new blade. Loosen the band saw blade guides and use the lever to release the tension on the old blade. Remove the old blade and tie it up into a coil to ensure it won’t do any harm.

Install the New Blade

Using the guide bearings on your saw, hold the blade in its correct place then hold the saw in place while tightening the tension. Once the tension is tight enough so that you don’t have to hold it in place, you can tighten it completely. Close the machine and adjust the blade guides so that they’re aligned again.

Choosing Band Saw Blades

Check the Blades

To make sure the blades are working correctly and aligned, do a test run of some spare stock. If your machine is vibrating this is a good indication that it hasn’t been aligned correctly so will require some adjusting.
