Bandsaw blades differ from hand hacksaw blades in that they are generally heavier, made in longer sizes, and have fewer teeth per inch. Typically, they can range from between 4 and 14 teeth per inch. However, the general rule is at least three full teeth must be on the work piece at any time still applies and to have less will cause a snag and tooth breakage. Even the most well-maintained bandsaw will finally experience failure as the blade wears and as it becomes blunt.
The risk of catastrophic failure increases. A blade will normally let you know that it is becoming blunt by an increase in noise, and a corresponding decrease in cutting ability. This might be gradual and you may not notice straight away.
Although it will become gradually more apparent. To reduce the chance of any unpleasant surprises we recommend that you plan to change the blade as part of your routine maintenance. Even the best blades can fail if there is something else wrong with your bandsaw, and even a small misalignment of bearings or guides can put a twist in the blade as it goes around. Resulting in tension being applied in all the wrong ways which will lead to early breakage. Misalignment tends to put the most stress on the joining weld and making that the primary point of failure.
Internal stress pinching on the blade is another common and avoidable cause of weld breaks. Weld breakage is generally thought of as a manufacturer problem but there are many instances where the problem may be avoided with a simple adjustment to your bandsaw.
