When to choose the 855140-6 springs?

Extra Long Wire: These springs are ideal for pulling out slack in the wire when cutting wire is longer than 8′ (2438mm).

Super Steep Tapers (4 Axis): They also work well when doing 4-axis cuts that require a steep taper by allowing the wire to stretch the extra length.
