Husqvarna SP33G is part of the X-Cut product line of chainsaw chains. SP33G is a high performance narrow kerf saw chain specifically designed for medium sized professional chainsaws. This chain makes a thinner cut than standard .325" pitch saw chain, so it requires less power from your chainsaw. Many users rave about the performance increases, especially when compared to standard saw chain. Narrow radius semi-chisel cutters have great stay sharp features, while still giving you fast cutting speeds. This chain has limited kickback reductions features, so it is recommeneded for professional use only. Sharpens with a 3/16" round file or 1/8" grinding wheel. SP33G will not perform well unless used in conjunction with a narrow kerf (pixel) bar. Made in Sweden.
