Objective

Students will understand the parts, safety procedures, and practical use of a power drill through guided content, bit identification, and a hands-on drilling activity.

Part 1: Introduction Reading

A power drill is a handheld electric tool used to drill holes or drive screws into wood, metal, plastic, or other materials. It typically includes key parts such as the chuck (which holds the bit), the trigger, the forward/reverse switch, the clutch for torque control, and the handle. Drills can be corded or cordless.

Common drill bits include twist bits for general drilling, spade bits for wider holes in wood, and driver bits for fastening screws.

To use a drill safely, always wear safety goggles to protect your eyes from debris, use hearing protection in extended use, and ensure the bit is securely fastened in the chuck. Clamp your workpiece when possible, and always remove the battery or unplug the drill before changing bits or making adjustments. Let the tool do the work—don`t force it.

Part 2: Drill Bit Identification

Part 3: Safety Checklist & Setup

Activity:

• Complete a Safety Checklist before drilling:

• PPE on (goggles, ear protection)

• Bit securely inserted in chuck

• Wood or material clamped

• Drill set to correct direction (forward or reverse)

• Battery charged or cord safe and untangled

Part 4: Hands-On Practice

Task:

• Drill 3–5 pilot holes in a 2×4 using a twist bit.

• Practice changing bits and adjusting the clutch.

• Try driving a screw with a driver bit.

Goal: Use the correct drill bit and maintain control while achieving clean holes or screw placement.

Part 5: Reflection

Activity:

• Write in your notebook:

• What went well?

• What was difficult?

• One safety rule you found most important
