The OTC Heavy Duty Snap Ring Pliers Set is designed to streamline in-shop service for the heavy duty vehicle technician. The heat-treated steel "circlip" pliers feature a spring ratchet locking mechanism that holds securely against snap ring tension, offering technicians a smoother, more comfortable experience when repairing large equipment. Also included in the kit are extra sets of replaceable .12" diameter tips, available in straight, 45-degree, and 90-degree angles. The set comes with a sleek blow-molded case to make for easy storage on the shop floor.
