Correct answer: Jigsaw
A jigsaw has a narrow reciprocating blade that allows it to follow curved and irregular cutting lines.
Question 2: What is the primary purpose of a countersink bit?
- To drill holes through metal
- To create a recess so a screw head sits flush with the surface (Correct answer)
- To enlarge existing holes
- To remove stripped screws
Correct answer: To create a recess so a screw head sits flush with the surface
A countersink bit creates a conical recess that allows the screw head to sit flush or below the material surface.
Question 3: What does the term 'kerf' refer to in woodworking?
- The angle of a blade's teeth
- The width of the cut made by a saw blade (Correct answer)
- The hardness rating of wood
- The grain direction of lumber
Correct answer: The width of the cut made by a saw blade
Kerf is the width of material removed by a saw blade as it cuts through wood or other material.
Question 4: A torque wrench is used primarily to:
- Remove rusted bolts
- Tighten fasteners to a specific tension (Correct answer)
- Measure bolt diameter
- Cut bolts to length
Correct answer: Tighten fasteners to a specific tension
A torque wrench applies and measures rotational force, ensuring fasteners are tightened to the manufacturer's specified torque value.
Question 5: Which material is most commonly joined using a soldering iron?
- Structural steel beams
- Copper electrical wiring (Correct answer)
- Hardwood furniture joints
- PVC plastic pipes
Correct answer: Copper electrical wiring
Soldering irons are used primarily for joining copper wires and electronic components using a low-melting-point filler metal (solder).
Question 6: What is the function of a tap in metalworking?
- To measure thread pitch
- To cut internal threads inside a hole (Correct answer)
- To cut external threads on a rod
- To deburr the edge of a metal sheet
Correct answer: To cut internal threads inside a hole
A tap is a cutting tool used to cut female (internal) threads inside a pre-drilled hole so a bolt can be screwed in.
Question 7: When using a hand plane, which direction should you work relative to the wood grain?
- Always against the grain
- With the grain (Correct answer)
- Across the grain at 90°
- Direction does not matter
Correct answer: With the grain
Planing with the grain produces a smooth surface; planing against the grain causes tearout and a rough finish.
