Bahco

Designed with holes for KASTO machines Designed for cutting almost any material High speed steel hacksaw blade Suitable for use on modern machines with skilled operators and a high degree of control 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
