Saw Blade Stripping and Breakage
Stripped bandsaw blade teeth is a common problem, and there are several causes to consider. A big factor includes use of the incorrect tooth pitch. Too small teeth for the size of the material fills gullets halfway through the cut. Pressure builds on a single tooth until it breaks and becomes lodged in the cut. Now the other teeth come in contact with the broken tooth, resulting in more broken teeth. Follow the m.o.m. rule: Minimum, Optimum, Maximum, which requires a minimum of 3- and a maximum of 24 teeth engaged in a cut in order to achieve the best …
Bandsaw Blade Set Types
Saw bands vary depending on blade type and also differ based on ability to resist heat and shock when entering and exiting the cut. These are important considerations when cutting structural, pipe, and tubing. An economical choice are the standard carbon steel blades with flexible backs and hardened cutting edges. They are used primarily for crosscutting wood and sawing brass, plastic, and mild steel. More expensive carbide-tipped blades are the essential tool for cutting harder metals, composite materials, and abrasive hardwoods such as teak. Bi-metal blades require more blade tension than most consumer-level machines can provide. A bandsaw blade’s resistance to flexing …
