3809-650-50-2.50-4-KA 4 TPI SANDFLEX® BI-METAL POWER HACKSAW BLADES FOR KASTO MACHINES 650 MM X 50 MM X 2.5 MM.

• 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
