A reliable source for Broaching information and leading Broaching Companies.

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.

Keyseater 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.

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.

The materials keyseaters commonly pierce through are metal, wood and plastic. Keyseating machines are almost always CNC run machines. Any object that has a lock requires the skills and operations of a keyseater.

Because of the varied materials that keyseaters must cut through, the material that they are made out of must be equally tough, if not more so. Diamond, cobalt, carbide and steel are all common materials for keyseaters, the first three being particularly effective for high speed machines. Coating is another necessity for keyseating machines, since the material is not about being corrosive resistant but doing the best job of keyseating consistently.

Therefore, coating processes such as anodizing, plasma spraying, ion plating, thermal spraying and electroless plating all increase the tool's hardness and resistance to abrasion, as well as making them sleeker. All of these characteristics contribute to the workable life of the keyseater.
