This blog is designed as a practical resource and toolkit for technicians and trade learners. It brings together three essential elements:
- A guide to commonly used trade tools and their correct usage.
- A comprehensive checklist of documents required for overseas job applications.
- Skill test practice guidance with templates and examples.
These actionable resources help you prepare effectively and return to this guide whenever you need a refresher.
1. Trade Tools Every Technician Should Know & How to Use Them
Tools are the backbone of every trade. Knowing what tool to use and how to use it safely and accurately improves job quality, efficiency, and workplace safety.
1.1 Hand Tools (Common Across All Trades)
- Screwdrivers (Flat & Phillips)
Used for tightening and loosening screws in electrical panels, machines, and fittings. Always choose the correct size to avoid damaging screw heads. - Spanners and Wrenches
Essential for tightening nuts and bolts. Adjustable spanners are useful for multiple sizes, while ring and open-end spanners provide better grip for fixed sizes. - Pliers (Combination, Long Nose, Cutting)
Used for gripping, bending, and cutting wires or small metal parts. Long nose pliers help in narrow spaces. - Hammer
Used in construction and fitting work. Ball-peen hammers are common in mechanical trades, while claw hammers are used in carpentry and civil work.
1.2 Electrical Trade Tools
- Multimeter
Measures voltage, current, and resistance. Essential for testing circuits and identifying faults. - Insulation Tester (Megger)
Checks insulation resistance to prevent leakage and short circuits. - Wire Stripper & Crimper
Used for removing insulation and attaching terminals to wires. - Voltage Tester (Tester Pen)
Quickly checks whether a wire or terminal is live.
Usage Tip:
Always test tools before use and ensure power supply is isolated before working on circuits.
1.3 Mechanical & Fitting Trade Tools
- Vernier Caliper & Micrometer
Used for precise measurement of internal and external diameters and thickness. - Torque Wrench
Ensures bolts are tightened to a specific torque value. - Bearing Puller
Used to remove bearings without damaging shafts. - File Set (Flat, Round, Triangular)
Used for smoothing edges and shaping metal.
Usage Tip:
Maintain tools clean and calibrated for accurate measurements.
1.4 Welding Trade Tools
- Welding Machine (Arc/MIG/TIG)
Used to join metal parts using heat and filler material. - Electrode Holder & Earth Clamp
Provide electrical connection for welding. - Chipping Hammer & Wire Brush
Used for cleaning slag after welding. - Welding Helmet & Gloves
Protect eyes and skin from heat and sparks.
Usage Tip:
Always use proper protective equipment and check electrode polarity before welding.
1.5 Civil & Construction Tools
- Spirit Level & Plumb Bob
Used to ensure structures are level and vertical. - Trowel & Float
Used for plastering and finishing concrete surfaces. - Measuring Tape & Chalk Line
For accurate layout and marking.
Usage Tip:
Correct measurement and alignment reduce rework and material wastage.
