Important issues regarding blade perfor-
mance:
• Scroll saw blades wear out and must be
replaced frequently. Typically a blade will
stay sharp anywhere from
1 ⁄
2
to 2 hours
depending on how the blade is used and
what type of material is being cut.
• Best cutting results will be achieved when
cutting material less than 1" thick.
• When cutting material thicker than 1", use a
very slow feed rate.
• Blades will become dull quickly whenever
making cuts in plywood, hardwoods, and
laminates.
• Exerting excessive side pressure on the
blade greatly increases the chance of blade
breakage.
