When choosing the industrial bandsaw blade best suited to your application, the blade’s tooth shape and form is a factor that also needs to be taken into account; use of the incorrect tooth type can lead to issued with the cutting performance of your bandsaw overall, teeth even fracturing or stripping from the blade in some situations.
In the below article, we aim to discuss the differences between the different bandsaw tooth types currently on the market, helping you to identify the option best suited to your cutting application.
The standard tooth is the tooth form seen to be used within the majority of general-purpose cutting applications, making it an ideal choice within a number of varying cutting applications. This industrial saw blade tooth type is typically characterised by its equally spaces teeth and 0° rake angle, causing it to be especially useful for smaller details within both wood and metal cutting projects.
A hook tooth can be identified by its positive rake angle, equally spaced teeth, and wide rounded gullets; this is seen to make this option one of the most aggressive tooth styles currently available.
The positive rake angle that this tooth holds helps to provide better material penetration without having to increase the feed pressure, helping to reduce the chances blade breakages and tooth fracturing, while the larger round gullet is able to transport large amounts of material from the cut when compared to other options. These characteristics result in a faster cutting speed that provides a great surface finish.
Similar to the standard tooth style, the skip tooth holds a 0° rake angle and equally spaces teeth, however, it also has wide flat gullets, helping to distinguish between the two available options. This coarse blade type works within cutting applications at a quick speed and is best suited for the cutting of long, gentle curves within non-ferrous and non-metal projects. The skip tooth also has a great chip carrying capacity.
The use of this tooth style is recommended within applications that involve brittle materials of a larger diameter, such as:
- Aluminium Risers
- Brittle Plastics
Variable Tooth Pitch
Variable tooth pitch is an option that’s qualities vary from tooth-to-tooth, some having a 0° rake angle while other hold a positive angle; Gullet depth and tooth spacing also varies along the blade. This variation is characteristics helps to reduce any vibrations during application, helping to improve blade life, reduce the amount of noise produced, and provide smooth and efficient cutting results.
Reduction in vibration makes this an option ideal for cutting applications that involve tubing or beams.
Overall, there are a number of different types of bandsaw blade tooth style currently on the market, meaning choosing the right one for you is sometimes a difficult, but highly important, task. Choosing the best tooth form for your application helps to ensure that you get the best performance from your bandsaw machine.
