Sherline's Cuttoff Tool and holder is used after completing a part in the lathe. IT is frequently necessary to separate the part from the excess material used for chucking. This operation is best accomplished with the use of a cutoff tool or "parting tool" as it is sometimes called.
The Sherline cutoff tool and holder consists of a very slender high-speed tool steel cutting blade mounted in a special holder.
The thinness of the blade. (.040"or 1mm) enables it to feed into the part quite easily, and , at the same time, minimizes the amount of waste material.
The turning speed for parting should be approximately one-half the normal turning speed for any given material. One word of caution; never use a parting tool on a part mounted between centers. The part can bind on the cutter and result in a scrapped part or a broken tool.
A small amount of cutting oil is a must. Parting off free maching material over a 1.00" (25mm) diameter will always be a problem on a machine of this size.
