IMPORTANT: ALWAYS USE GOOD QUALITY BLADES
BLADES BREAK FOR FIVE PRINCIPAL REASONS:
1. Too much tension or too little tension on the blade.
2. Overworking the blade by feeding the workpiece too fast.
3. Twisting or bending the blade by feeding the workpiece off-centre.
4. Over use - the blade has reached the end of its useful life.
5. Feeding too much material into the saw, - more than the maximum 2" depth for
which it was designed.
HOW TO DETERMINE THE RIGHT BLADE FOR THE JOB
This scroll saw accepts a wide variety of blade widths and thicknesses. The width of the
blade , the thickness of the blade, and the number of teeth per inch (TPI) are determined
by the type of material and size of the radius being cut. Here are several examples:
TPI WIDTH THICKNESS MATERIAL
10 2.8mm 0.5mm Medium curves on 1/4" to 1-3/4" wood, wallboard,
0.11" 0.020" hardboard.
15 2.8mm 0.5mm Same as above, plus wood 1/8" to 1-1/2" thick
0.11" 0.020"
18 2.4mm 0.25mm Extra thin cuts on soft woods to 1/4" and parquetry
0.095" 0.011
As a general rule, select the narrowest blades recommended for intricate curve cutting
and widest blades for straight and large curve operations.
