What type of cutter is designed to make cuts with a rectangular shape on a key?

  1. Round Cutter

  2. Triangular Cutter

  3. Slotter

  4. Chisel Cutter

The correct answer is: Slotter

The slotter is specifically designed to create rectangular-shaped cuts, which is essential for accurately shaping keys. This type of cutter operates to produce the flat, straight edges required for the grooves and cuts found on keys. The slotter can efficiently remove material in a manner that achieves the precise geometry needed for effective key function and compatibility. Other types of cutters, such as the round cutter, triangular cutter, and chisel cutter, are employed for different applications. The round cutter is mainly used for creating circular shapes, the triangular cutter is used for pointy cuts, and the chisel cutter is primarily used for engraving or creating slopes, none of which would produce the specific rectangular profiles required for key cutting. Therefore, the slotter is the most appropriate choice for producing the desired shapes necessary on keys.
