Introduction to Manual Tools

Overview of Manual Tools

• The session introduces various manual tools, focusing on their handling and types.

• Emphasis is placed on the importance of understanding tool specifications, particularly for cutting materials.

Types of Tools Discussed

• The discussion includes chisels used in construction, highlighting their varying angles (35 to 60 degrees) based on material type.

• Mention of scissors and guillotines as essential tools in mechanical workshops for cutting sheets of different thicknesses.

Specific Tool Functions

Chisels and Their Applications

• Chisels are described as forged steel tools used for making holes in sheets; they come with a cylindrical body and variable angles depending on application.

• The angle range for chisels is noted to be between 90 to 120 degrees, allowing precise centering when drilling.

Importance of Marking Holes

• A marking tool is recommended before drilling to ensure accuracy; this prevents misalignment during the drilling process.

Additional Tools in Mechanical Work

Hammers and Their Uses

• Hammers made from carbon steel are discussed, noting their use in riveting and shaping small parts.

• Different types of hammers are mentioned, including rubber or nylon hammers used for finishing touches without damaging surfaces.

Conclusion on Tool Usage

• The importance of selecting the right hammer based on the task at hand is emphasized, especially when working with rolling components.
