Power Hack BAHCO Sandflex

Bahco 4 Dpp Sandflex® Bimetal Machine Saw Blades 450 Mmx38 Mmx2 Mm. 4 TPI Sandflex® Bi-Metal Power Hacksaw Blades 450 mm x 38 mm x 2 mm.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. tradeinn Bricoinn
