Bandsaw Blade Education

To choose a bandsaw blade, first start with what you are cutting, Wood or Metal? When cutting wood you will want to decide if you are cutting straight cuts or radius cuts. In general, it is recommended to use the widest blade your saw will allow and for radius cuts you will want a 3/4″ width or below, depending on the radius you want to achieve.

Bandsaw Guides and Blades


Wood Cutting – We carry 3 styles of wood cutting bandsaw blades. Proforce, Shear Force and the Resaw King.

Proforce – Direct from Sweden, our Proforce blade stock is the finest on the market. You will immediately notice the difference in quality and precision with the Proforce. The Proforce is an affordable blade without compromising the cut.

Shear Force – Made in the USA, the Shear Force blade is compatible with nearly every bandsaw. Manufactured with an ultra-thin .024″ backing and alternating 3-4 TPI it ensures a smoother cut and significantly reduced vibration. This blade is a specialty blade that not only works on wood but works great on cardboard, meats with bone, frozen meats, hard foams, soft plastics and

Resaw King – The Resaw King is perhaps the world’s finest resawing blade. Manufactured with C4 carbide teeth, this blade allows you to cut ultra-smooth, wafer-thin veneers with minimal waste. Woodworkers demanding the best will be impressed. The triple vari-tooth design minimizes vibration and lowers harmonics. Teeth are individually brazed and ground to perfection using diamond wheels on our custom-built Shark grinder designed exclusively for this blade.

The Resaw King is the ideal blade for anyone cutting hardwoods or exotics, providing ultra smooth cut quality with minimal material loss. Nearly a decade in the making, the Resaw King has been skillfully finessed into one of the best woodworking blades in the world. Created by Torben Helshoj, an award winning woodworker, the Resaw King displays his passion for the art. Made from a C4 carbide tipped alloy, the Resaw King can be resharpened 4-5 times! Variable tooth spacing significantly reduces vibration while producing sleek smooth cuts. This dynamic blade also cuts down wood waste due to its ultra-thin kerf and backing material, saving you money.

The Resaw King is manufactured in Germany exclusively for LAGUNA and is perfected here, in the USA, by our skilled team of professionals using our full line of CNC machines.

How to Choose the Correct Number of Teeth Per Inch (TPI)

The number of teeth per inch (TPI) is important in obtaining the finish desired and the proper feed rate. A coarse tooth blade (2, 3 TPI) should be used for re-sawing wood and cutting thicker stock up to 8″ thick. A fine toothed blade (18 to 32 TPI) should be used for thinner metals and plastics under 1/4″. For general cutting of 3/4″ plywood 4 TPI will provide a fast cut and 14 TPI will cut much slower but leave a smooth finish on the cut.

When Selecting TPI Remember:

  • More TPI gives a smoother but slower cut.
  • Fewer TPI allows for a faster cut with a slightly rougher cut surface.
  • Should have at least 3 teeth and less than 12 teeth in the work piece.


PITCH/TPI- The distance from the tip of one tooth to the tip of the next tooth. This is usually quoted in teeth per inch (T.P.I.). The larger the tooth, the faster the cut, because the tooth has a large gullet and has a greater capacity to transport large amounts of sawdust through the job. Generally, the larger the tooth, the coarser the cut, and the poorer the surface finish of the cut. But with the Resaw King, you get the advantage of a fast cut and a good surface finish. The smaller the tooth, the slower the cut, as the tooth has a small gullet and cannot transport large amounts of sawdust through the job. The smaller the tooth, the finer the cut and the better the surface finish of the cut. It is normally recommended that you have 6 to 8 teeth engaged in the cut. This is not a rule, only a general guide. If you have fewer teeth engaged, there is a possibility that juddering or vibrating will result, as there is a tendency to over-feed the job and for each tooth to take too deep a cut. If fewer teeth are engaged, there is a tendency to overfill the gullets of the tooth with sawdust. Both problems can be overcome to a degree by adjusting the feed rate. There are certain indications if a blade has the correct pitch or if the pitch is too fine or too coarse.


Blades cut quickly.
A minimum amount of heat is created when the blade cuts.
Minimum feeding pressure is required.
Minimum horsepower is required.
The blade makes quality cuts for a long period.


The blade cuts slowly.
There is excessive heat, causing premature breakage or rapid dulling.
Unnecessarily high feeding pressure is required.
Unnecessarily high horsepower is required.
The blade wears excessively.


The blade has a short cutting life.
The teeth wear excessively.
The band saw or blade vibrates.

THICKNESS- The thickness of the band “gauge.” The thicker the band, the stiffer the blade and the straighter the cut. The thicker the band, the greater the tendency for the blade to break due to stress cracking, and the larger the bandsaw wheels have to be.

4-6 Inches .014″
6-8 Inches .018″
8-11 Inches .020″
11-18 Inches .025″
18-24 Inches .032″
24-30 Inches .035″
30 Inches and Over .042″, .050″, .063″
These are the recommended sizes for optimal blade use. If your blade is too thick for your wheel diameter, it will crack.

When choosing the blade with the proper pitch, one factor you should consider is the hardness of the material that is being cut. The harder the material, the finer the pitch that is required. For example, exotic hard woods such as ebony and rosewood require blades with a finer pitch than hard woods such as oak or maple. Soft wood such as pine will quickly clog the blade and decrease its ability to cut. Having a variety of tooth configurations in the same width will most likely give you an acceptable choice for a particular job. The Resaw King will cut most woods, but it must be noted that when cutting woods with a high silicon content or very hard woods such as iron wood, ebony, etc., the blade will dull more quickly than when cutting soft woods.

The width of the saw cut.
The larger the kerf, the smaller the radius that can be cut. But the greater the amount of wood that the blade has to cut and the greater the
horsepower that is needed, as the blade is doing more work. The greater the kerf, the larger the amount of wood that is being wasted by the cut.

The cutting angle or shape of the tooth.
The greater the angle, the more aggressive the tooth, and the faster the cut. But the faster the cut, the faster the tooth will blunt, and the poorer the surface finish of the cut. Aggressive blades are suitable for soft woods but will not last when cutting hard woods.
The smaller the angle, the less aggressive the tooth, the slower the cut, and the harder the wood that the blade is suitable to cut.
Hook teeth have a progressive cutting angle and take the form of a progressive radius. They are used for fast cutting where finish is not important.
Rake teeth have a flat cutting angle and are used for fine surface finish of the cut.
The Resaw King has a rake tooth form. The tooth and gullet are ground in one continuous process that greatly enhances the performance of the blade, giving a fast cut with a good surface finish to the wood.


The area for the sawdust to be transported through the wood. The larger the tooth (pitch), the bigger the gullet.

The angle from the tip of the tooth back. The greater the angle, the more aggressive the tooth, but the weaker the tooth.

This is the ability of the blade to resist bending backwards. The wider the blade, the stronger the beam strength; therefore, a 1″ blade has far greater beam strength than a 1/8″ blade and will cut straighter and is more suitable for resawing.

There is not very much that needs to be maintained on the blade, but below are a few points that will help you keep your blade in peak cutting performance.

Always clean the blade when you take it off the machine. If you leave it gummy or with wood in the gullets, the blade will rust. Rust is the enemy of the woodworker. When you take the blade off the machine or you are not going to use it for some time, it is recommended that you wax the blade. Have a rag that is impregnated with wax that you pull the blade through backward. The wax will coat the blade and will give a degree of protection against rust.


Inspect the blade for cracks, dull teeth, rust and general damage every time you put it on the machine. Never use a dull or damaged blade; they are dangerous. If your blade is dull, have it re-sharpened or replace it.

Store the blade so that the teeth are not damaged and will not cause you injury. One method is to store each blade on a hook with the teeth against a wall. Nail cardboard or a wood sheet on to the wall so that the teeth are protected from damage, and if you brush against the blade it will not cause injury.

Please note: Your bandsaw blade length and width parameters can be located on the back of your saw on a plate above the motor.

Please refer to your bandsaw for blade length. Many lengths have changed and we highly recommend you check your original order before ordering online. If you are unsure – call 800-234-1976.
