【Chain Type】As an enhanced security chain with a low-kickback design, it adopts premium materials that outperform standard steel and features hardened rivets for enhanced connectivity—these attributes significantly lower the risk of breakage and minimize accident hazards. Meanwhile, as a ripping chain type, it is equipped with longer teeth, deeper gullets, and flat cutting surfaces, which enable it to cut through wood faster and clear debris better.
