What Is a Chisel?
A chisel is a tool designed for processing hard materials such as metal, rock, concrete, and more. They come in various types, each with differently shaped tips to suit specific purposes. The tip of a chisel is typically wider and sharpened for effective scraping and cutting.
Uses of Chisels
Chisels are used in a range of applications, including cutting thin steel plates, scraping old concrete, and removing metal burrs, and spatter from welding. They are most effective for manual processing of small parts. For tougher materials or thicker boards, chisels are often used in conjunction with a hammer to strike and break the material. They are also used for breaking bricks and blocks in construction and home remodeling projects.
Principle of Chisels
Chisels are typically made of steel, a material stronger than the objects they are designed to process. High-frequency quenching is often used in the manufacturing of chisels to enhance their strength. While chisels are not extremely sharp, caution is still necessary to prevent injury.
Different types of chisels are tailored for specific uses:
- Flat Chisels: Bar-shaped with a wider tip, suitable for general applications.
- Brick Chisels: Feature a spatula-like wide tip, ideal for breaking bricks and stones.
- Cut Chisels: Similar to brick chisels, used for removing blocks and road signs.
- Slot Chisels: Have a flat handle and tip, suitable for sheet metal and burr removal.
- Tester Chisels: Characterized by a thin, pencil-like tip, allowing for precise application of force.
