Sandflex® Bi-metal Power Hacksaw Blades for KASTO machines

3809 KA
Product Details
  • Designed with holes for KASTO machines
  • 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
