Bandsaw Blade Size
Choosing the correct blade size for your bandsaw is essential to ensure proper tension and tracking. Bandsaw blade sizing involves the length, width, and thickness of the blade.
Bandsaw Blade Length
Identifying the correct blade length for your bandsaw is essential for ensuring proper fit, tension, and optimal cutting performance. The length of a bandsaw blade refers to the total measurement of the blade's circumference.
To determine the appropriate blade length for your bandsaw, follow these steps:
Consult the User Manual or Manufacturer's Specifications: The easiest way to find the correct blade length for your bandsaw is to consult the user manual or manufacturer's specifications. Most bandsaw machines will have a recommended blade length range specified by the manufacturer. Using a blade within this range will ensure compatibility with your machine.
Measure Your Bandsaw: If the user manual or manufacturer's specifications are unavailable, you can measure your bandsaw to determine the proper blade length. To do this:
Release the tension on the bandsaw blade and remove it from the machine.
Measure the distance from the centre of the top wheel to the centre of the bottom wheel (also known as the wheel centres' distance). Note this measurement.
Measure the diameter of the top and bottom wheels. They should be the same size. Note this measurement.
Calculate the blade length using the following formula:
Blade Length = (Wheel Centers Distance x 2) + (3.14 x Wheel Diameter)
This calculation will give you an approximate blade length for your bandsaw.
Find a Suitable Standard Length Blade: Bandsaw blades are often available in standard lengths to fit a range of bandsaw machines. Once you have determined the approximate blade length for your bandsaw, choose the closest standard length available. Most bandsaw machines have some adjustability, allowing you to accommodate slight variations in blade length.
Order a Custom Length Blade: At Any Length we provide customisation options that enable you to buy exactly the length of blade that you need. This means that you can be sure to achieve a perfect fit for your new blade.
Bandsaw Blade Width
Blade width determines the minimum radius of the cuts that can be made.
Identifying the appropriate blade width for your bandsaw is crucial for achieving optimal cutting performance, accuracy, and machine stability. The width of a bandsaw blade refers to the distance from the front cutting edge to the back of the blade.
Common widths include:
6mm (¼”)
10mm (⅜”)
13mm (½”)
20mm (¾”)
27mm (1”)
34mm (1 ¼”)
41mm (1 ½”)
Wider blades are more suitable for straight cuts, while narrower blades are ideal for intricate cuts and curves. To determine the correct blade width for your specific cutting tasks and bandsaw machine, consider the following factors:
Bandsaw Machine Specifications: Consult your bandsaw machine's user manual or manufacturer's specifications to determine the minimum and maximum blade width that your machine can accommodate. This range will give you a starting point for selecting the appropriate blade width for your needs.
Cutting Applications: The type of cutting tasks you plan to perform plays a significant role in determining the blade width. For general-purpose cutting and straight cuts, a wider blade is usually more suitable, as it provides increased beam strength and stability, resulting in straighter and more accurate cuts. On the other hand, if you need to perform intricate or curved cuts, a narrower blade width is necessary, as it allows for a smaller cutting radius and increased manoeuvrability.
Blade Stability and Deflection: Wider blades are less prone to deflection and twisting during cutting operations, which can lead to more accurate and consistent cuts. If your cutting tasks require high precision and stability, opt for a wider blade within your bandsaw's capacity.
Kerf Width: Wider blades generally produce a wider kerf (the width of the material removed during the cut), which can be advantageous when cutting thick materials or when increased chip removal is desired. However, narrower blades produce a smaller kerf, which can be beneficial for minimising material waste and improving cutting efficiency for thinner workpieces.

Bandsaw Blade Tooth Types
Teeth on a bandsaw blade are responsible for cutting the material. Different teeth types and configurations are available to optimise cutting performance for specific materials and applications.
When it comes to selecting the most appropriate bandsaw blade for a task, there are a range of teeth types and arrangements to choose from:
Regular Tooth: Using straight teeth, these blades are used for making regular cuts on metal and wood.
Hook Tooth: Featuring a positive rake angle, hook teeth are ideal for cutting thicker materials and provide fast, aggressive cuts in wood and non-ferrous metals.
Skip Tooth: With a wider gullet, skip teeth provide better chip clearance, making them suitable for cutting softer materials such as plastics and non-hardened metals.
Variable Tooth: With teeth of different sizes set in an alternating configuration, these blades are often used for woodworking and can provide a smooth finish to a range of cuts.
Bandsaw Blade Tooth Sets
In addition to the type of teeth used on a blade, tooth sets describe the way in which teeth are arranged on the blade:
Standard (Or Raker) Tooth Set
A raker tooth set is a common tooth configuration found on bandsaw blades, designed for general-purpose cutting across a wide range of materials, including wood, metal, and plastic.
In a raker tooth set, the teeth are arranged in a repeating pattern along the cutting edge of the blade, typically consisting of one straight (or unset) tooth, known as the raker, followed by two teeth that are set in alternating directions (one to the left and one to the right).
The raker tooth set configuration offers several key benefits:
Versatility: The raker tooth set is well-suited for a wide variety of cutting applications and materials, making it an excellent choice for general-purpose bandsaw blades. It can efficiently cut through wood, metal, and plastic, providing a good balance of cutting speed and surface finish.
Good Chip Clearance: The alternating tooth set pattern, combined with the straight raker tooth, allows for effective chip clearance during cutting operations. This helps reduce cutting resistance, prevents chip buildup, and contributes to improved cutting efficiency and blade longevity.
Reduced Tooth Stripping: The raker tooth helps distribute the cutting forces more evenly across the blade, which can reduce the risk of tooth stripping, especially when cutting harder materials. This contributes to a longer blade life and more consistent cutting performance.
Smooth and Efficient Cutting: The alternating tooth set pattern and raker tooth work together to create a smooth and efficient cutting action. This results in straight, precise cuts with a relatively smooth surface finish, making it suitable for various woodworking, metalworking, and plastic cutting tasks.
Wavy Tooth Set
A wavy tooth set is a specific tooth configuration found on bandsaw blades, designed to provide smoother cuts and reduced noise, particularly when cutting thin or delicate materials.
In a wavy tooth set, the teeth are arranged in a sinusoidal, wave-like pattern along the cutting edge of the blade, as opposed to the more common alternating tooth set pattern found in regular raker or hook tooth configurations.
The wavy tooth set configuration has several key benefits:
Smoother Cuts: The wave-like pattern of the teeth distributes the cutting forces more evenly across the blade, resulting in less aggressive cuts and a smoother surface finish. This is particularly advantageous when cutting thin materials, such as sheet metal, tubing, or plastic, which may be prone to distortion or vibration during cutting.
Reduced Noise and Vibration: The wavy tooth set design can help minimize noise and vibration during cutting operations, as the teeth engage with the material more gradually and consistently. This can lead to a more comfortable and quiet working environment, as well as reduced tool wear.
Improved Chip Clearance: The wavy tooth set can also provide enhanced chip clearance, as the varying tooth height and geometry create additional space for chip removal. This can help prevent chip buildup, reduce cutting resistance, and improve overall cutting efficiency.
Versatility: Wavy tooth set bandsaw blades are suitable for a wide range of materials, including metal, plastic, and wood. They are often used in applications where a smooth, clean cut is desired, such as cutting tubes, pipes, or thin-walled profiles.
Alternative Tooth Set
An alternative tooth set, also known as an AT set, is a tooth configuration commonly found on bandsaw blades, particularly those designed for wood cutting applications. In an alternate tooth set, the teeth are arranged in a simple alternating pattern along the cutting edge of the blade, with one tooth set to the left and the next tooth set to the right.
The alternative tooth set configuration offers several key benefits:
Straight Cuts: The simple alternating pattern of the teeth helps to guide the blade in a straight line during cutting operations, resulting in straight and accurate cuts. This is particularly useful for woodworking tasks where precision is essential.
Efficient Chip Clearance: The alternating tooth set pattern creates channels that allow for effective chip clearance during cutting operations. This helps to reduce cutting resistance, prevent chip buildup, and maintain a clean cutting surface, contributing to improved cutting efficiency and a smoother finish.
Versatility: The alternate tooth set is suitable for a wide range of cutting applications and materials, including various types of wood, plywood, and laminates. It provides a good balance of cutting speed and surface finish, making it a popular choice for woodworking projects.
Smooth Surface Finish: The alternating tooth set can produce a relatively smooth surface finish on the workpiece, as the teeth engage the material in a consistent and evenly distributed manner. This can reduce the need for additional sanding or finishing processes, saving time and effort.
Reduced Blade Binding: The alternating tooth set can help minimise blade binding, as the set pattern allows the blade to move more freely through the material. This can lead to a more comfortable and efficient cutting experience, especially in thicker or denser materials.
Selecting The Correct Bandsaw TPI
TPI refers to the number of teeth per inch on a bandsaw blade, affecting the cutting speed and finish. A higher TPI value results in smoother cuts but slower cutting speed, while a lower TPI value provides faster cutting speed with rougher cuts.
Broadly speaking, a blade with a TPI in the range of 6 to 8 is considered to be a good general purpose blade. Blades in the range of 14 TPI and above would usually be recommended for cutting thinner materials.
TPI For Solid Wood
A lower TPI is suitable for rough cuts, while a higher TPI provides a smoother finish.
TPI For Non-Ferrous Metals
For cutting metals such as aluminium and copper, a higher TPI such as 8-12 or 10-14 is recommended to ensure clean cuts and to prevent clogging.
TPI For Ferrous Metals
Cutting harder metals like steel typically requires a higher TPI, such as a 10-14 bi-metal option for better heat dissipation and durability.
TPI For Acrylic Or Polycarbonate
For thin plastics, such as acrylic or polycarbonate sheets, a higher TPI is recommended. This will help to prevent chipping and ensure a clean, smooth cut.
TPI For Medium & Thicker Plastics
For medium thickness plastics (1/4 to 1/2 inch thickness), a blade in the 4-6 TPI range is generally suitable. This will provide a balance between cutting speed and surface finish. For thicker plastics (greater than 1/2 inch thickness), a lower TPI such as 3-4 may be more appropriate. This will help to prevent excessive heat buildup and reduce the risk of the material melting during cutting. However, the trade-off is that the finish might not be as smooth as with a higher TPI blade.
TPI For Fibreglass & Carbon Fibre Composites
For cutting fibreglass or carbon fibre composites, a higher TPI is typically recommended. The finer tooth geometry helps to minimise chipping and delamination, providing a cleaner cut.
TPI For Particleboard, MDF & Wood-Based Composites
For cutting wood-based composites, such as particleboard or medium-density fiberboard (MDF), a TPI of between 6 and 10 is generally suitable. This provides a balance between cutting speed and surface finish.
