METAL-CUTTING TOOLS
LEARNING OBJECTIVES: Identify the
different types of metal-cutting tools. Describe
the uses of different types of cutting tools.
Many types of metal-cutting tools are used by
skilled mechanics of all ratings. As you become better
acquainted with the ABE rating, you will probably
discover many tools that you use for cutting metal that
are not described in this text. In this text, only the basic
hand metal-cutting tools will be considered.
SNIPS AND SHEARS
Snips and shears are used for cutting sheet metal
and steel of various thickness and shapes. Normally, the
heavier or thicker materials are cut by shears.
One of the handiest tools for cutting light (up to
1/16-inch thick) sheet metal is the hand snip (tip snips).
