BLADE SELECTION
There are a variety of different types of bandsaw blades on the market to suit various cutting applications. Your results
may vary based on usage, experience and personal preference.
Standard size - 112” (2845 mm) - replacement blades made from high carbon steel can be purchased in a variety of
widths from your General® International dealer under the following parts numbers:
• #90170-B14:1/4” - 6 TPI, blade thickness: 0.65 mm • #90170-B38: 3/8” - 6 TPI, blade thickness: 0.50 mm
• #90170-B12: 1/2” - 4 TPI, blade thickness: 0.65 mm • #90170-B34: 3/4” - 4 TPI, blade thickness: 0.65 mm
or (depending on availability) from your local tool dealer. These are standard sizes that should be readily available
in most areas. The use of any other size is not recommended and can lead to serious injury and/or damage to the
machine.
Some general guidelines to consider when choosing bandsaw blades:
• Wider blades with fewer teeth per inch are best suited to cutting straight lines, re-sawing and for sweeping curves,
but will not turn tight radius curves. They will cut quickly and aggressively but do have a tendency to bind (or get
stuck in the cut) if turned too sharply.
•Narrower, thinner blades with more teeth per inch will cut more slowly but can turn much tighter corners for cutting
more intricate work.
Common causes of blade breakage:
• Poor guide bearing alignment and adjustment. • Feeding the workpiece too quickly.
• Forcing or twisting a wide blade around a short radius. • Dull teeth.
• Setting blade guard assembly too high above the workpiece. • Too much blade tension.
• Lumpy or improperly finished braze or weld on the blade.
• Continuous running of blade when not cutting.
