Choosing Bandsaw Blades
The bandsaw is undoubtedly one of the most versatile machines in the workshop, but getting the best out of it requires choosing the most appropriate blade for the task at hand. Blades vary in three primary ways – tooth type, tooth pitch and band width. The following factors will greatly influence the choice of blade in one or more of these variables.
Material to be cut
Bandsaws can be used to cut materials other than wood and this is a prime factor in selecting a blade for the task. They are commonly used to cut non-ferrous metals (such as brass, copper, aluminium), acrylic and other rigid plastics, frozen flesh and carcasses, and even ice (my local tackle store has a small bandsaw).
Wood is a little more forgiving in blade selection in this regard, but some materials require specific types to be successful. Some non-ferrous metals for example, require a carbidetipped blade whilst acrylics require a very fine pitch to cut successfully.
Blade wear can be a factor here too – I’ve been in shops with multiple saws set up, including one solely for cutting out curved template components in sheet goods, which are notoriously abrasive on
