A keyseater is a machine used to make the keyway hold inside a locking mechanism. Keyseaters are a type of broaching machine, which is a tool with a row of sequentially larger teeth used to cut holes and to make grooves in a material’s surface. The most common use of a keyseater machine would have to be the shaping of keyholes for locks.

Keyseaters are also known as keyway broaching machines, keyway cutters and keyseat cutters. They are a subcategory of internal broaching, which is a specific type of broaching that puts a hole from one surface side of a material through to the other side of the material, unlike blind broaching, which only involves surface work. These machines function by way of a topside support and guiding system, which ensures that the cuts are clean and precise. The cut comes from below the work-piece and cuts on the down stroke. The guiding system, usually a vise or clamp, keeps the material in place, and is either fed through the cutter manually, if the table is permanent, or if the table is moveable this happens automatically. The piece being cut moves horizontally, while the keyseater cutter moves vertically. Although keyseaters are best known for cutting key holes, they are also capable of making other cuts, including cuts that do not fully penetrate. Examples of other products are tools like wrenches, fasteners and bushings.
