Lesson Content/Board Summary

METAL WORK HAND TOOLS

Driving Tools

Driving tools are used to strike or hit objects, such as nails, chisels, or punches. They are designed to transfer force effectively.

The following are types of driving tools:

Hammers: These are common driving tools. Examples include:
- Claw Hammer: Used for driving nails and pulling them out.
- Ball-peen Hammer: Used for shaping metal, riveting, and setting punches.
- Sledgehammer: A heavy hammer used for heavy-duty work like breaking concrete or driving large stakes.
Mallets: Usually made of wood, rubber, or plastic, used for striking surfaces that should not be damaged by a metal hammer.

Cutting Tools / Boring Tools

Cutting tools are used to remove material from a workpiece to change its shape or size. Boring tools are a type of cutting tool specifically used to create or enlarge holes.

The following are types of cutting and boring tools:

Hacksaw: Used for cutting metal. It consists of a frame and a replaceable blade with fine teeth.
Chisels: Used for cutting, shaping, or carving metal.
- Cold Chisel: Used for cutting cold metal.
Files: Used for removing small amounts of material, smoothing surfaces, and sharpening edges. They come in various shapes and cuts (e.g., flat, round, half-round).
Hand Drill: A portable tool used for making holes in various materials by rotating a drill bit.
Brace and Bit: A hand-powered tool used to drill holes, especially in wood, but can be used for softer metals with appropriate bits.

Care and Maintenance of Metal Work Hand Tools

Proper care and maintenance ensure tools last longer, perform better, and are safe to use. Here are key practices:

Cleaning: Always clean tools after use to remove dirt, grease, and metal shavings.
Lubrication: Apply a thin coat of oil to metal parts to prevent rust, especially on cutting edges and moving parts.
Sharpening: Keep cutting and boring tools sharp. Dull tools are less efficient and can be dangerous.
Storage: Store tools in a dry, organized place, such as a toolbox, tool rack, or cabinet. Ensure they are not piled up to prevent damage.
Inspection: Regularly inspect tools for damage, wear, or loose parts. Replace or repair damaged tools immediately.
Safe Handling: Use tools for their intended purpose only. Wear appropriate personal protective equipment (PPE) like safety glasses and gloves.
