What are holding tools?

Holding tools are devices used to hold a workpiece firmly in place while you cut, file, saw, drill, solder or glue. They keep the object steady so work is safe and accurate.

Common holding tools (with simple pictures)

Where you might use them (Kenyan examples)

• Repairing a bicycle chain — use a bench vice or locking pliers to hold the wheel or chain.
• Carving a stool — hold wood in a vice or with clamps when chiselling or sawing.
• Fixing a jiko (cookstove) or metal pan — use bench vice to hold metal while filing or welding.
• School practicals — holding materials steady during measuring, drilling or gluing.

How to choose the right holding tool

1. Size of workpiece — big pieces need a bench vice or long clamps; small pieces need hand vice or pliers.
2. Type of work — heavy metalwork needs a strong vice; woodworking often uses clamps that do not dent the wood.
3. Shape of the object — use locking pliers for round pipes; flat jaws for boards and plates.
4. Protect the surface — use soft jaws (wood or leather pads) when clamping finished surfaces.

How to hold work safely — step by step

1. Choose the right tool for the job.
2. Position the workpiece so you can reach the place to be worked on comfortably.
3. Place soft pads between the jaws and the work if the surface must not be damaged.
4. Tighten the clamp or vice steadily until the workpiece cannot move — do not over-tighten.
5. Check that tools (saw, file, drill) have a clear path and will not hit the clamp or your hands.

Safety rules

• Always wear safety goggles when cutting, drilling or filing.
• Do not put your hands between the jaws — use a stick or brush to clear chips.
• Keep clamps and vices clean and free from oil to prevent slipping.
• Use gloves when handling sharp metal, but remove loose gloves around rotating machines.
• Do not use a vice as an anvil or hit the vice with a hammer unless it is made for that.

Care and maintenance

• Keep the screw and moving parts oiled lightly so they turn smoothly.
• Clean jaws of dirt and filings after use.
• Check for cracks or bent parts — report or replace if broken.
• Store small hand-holding tools in a box or on a pegboard to avoid loss.

Simple classroom practical (10–20 minutes)

Practice: Clamp and cut a small wooden scrap safely.

1. Materials: wooden scrap, bench vice or G-clamp, hacksaw or hand saw, safety goggles, scrap wood pad.
2. Steps:
   1. Place the scrap on the bench. Put a soft pad between the scrap and the vice jaws.
   2. Clamp the scrap so that about 1/3 of the piece sticks out for cutting.
   3. Wear safety goggles. Hold the saw with both hands and cut smoothly, keeping your hands away from the blade.
   4. After cutting, loosen the clamp and remove the workpiece.
3. Check: The scrap did not move; edges are neat; no injuries.

Glossary (simple)

• Jaw: The part of a clamp or vice that touches the workpiece.
• Screw: The threaded rod used to tighten a vice or clamp.
• Soft jaw: A protective cover (wood, leather or rubber) used to avoid marks on the work.
