With regard to bandsaw blade terminology, it is important to note the different types of saw blade teeth, the terminology, and their usage. Hopefully, this post will help to clear up any misconceptions while offering sensible advice toward the purchase of a new saw blade for a particular cutting operation.
Here they are in no particular order:
- Regular Tooth Style: zero° rake angle on the blade tooth; full, well rounded gullets, a strong supporting back tooth, and all tooth shapes are the same.
- Skip Tooth Style: zero° rake angle on the blade tooth, skip tooth style blades have double the gullet capacity in order to handle more and larger chips, and again, all tooth shapes are the same.
- Sabre Tooth Style: ten° positive rake angle on the blade tooth, deeper, more rounded gullets than regular or skip tooth style blades, allows for faster feeding, has less tendency to clog under a heavy chip load and all tooth shapes are the same.
- Variable Tooth (Pitch) Style: Regular tooth pattern is broken up to reduce noise, there is less vibration and chatter, one blade is suitable for a wider range of cutting needs, the tooth pattern is repeated throughout the band, and the tooth shape changes within the pattern.
- Triple Chip Tooth Style: Carbide tipped for cutting high nickel alloys and exotic steels, triple chip teeth are ground to provide a good side clearance, designed for high production applications where a good smooth surface finish is needed.
I hope this helps to clarify the different types of bandsaw blades available and their specific design qualities for the particular types of materials being cut today.
