PRODUCT DETAILS
- 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
