•Suitable for use on any material
Sandflex® is virtually an unbreakable bi-metal hacksaw blade
Shatterproof blade that can withstand high feed pressures yet giving accurate, fast cutting rates
Sandflex® blades are safer to use in all circumstances, especially on old machines or with unskilled operators
Correct blade tension is essential for ensuring a straight kerf and a long useful life of the blade
If the tension is too low, the blade will bend upwards or twist, giving rise to high stresses, heavy wear of the blade and uneven, crooked kerfs
Excessive tension causes high stresses in the blade and saw frame
As a general rule, harder materials call for a lower stroke rate and higher feed pressure
If the chips are burnt, feed pressure is too high
If tooth cracks appear, feed pressure is too high
Fine, powdery chips indicate that feed pressure is too low
Fine curled chips indicate the optimal feed pressure
The teeth should not be touching the workpiece when the machine is started
A useful rule of thumb is that at least three teeth should be engaged at any time
