Introduction To Hand Tools

Hand tool is any of the implements used by craftsmen in manual operations, such as chopping, chiseling, sawing, filing, or forging. Complementary tools, often needed as auxiliaries to shaping tools, include such implements as the hammer for nailing and the vise for holding. Virtually every type of tool can be a hand tool, although many have also been adopted as power tools which get their motive power from engines rather than from people.

WRENCHES or SPANNERS . A tool used to provide a mechanical advantage in applying torque to turn bolts, nuts or other hard-to-turn items. Spanner refers to a specialized

wrench with a series of pins or tabs around the circumference. There are two types of wrenches or spanners; An open-end wrench, a wrench with a U-shaped opening that grips two opposite faces of the bolt or nut. And the ring spanner, a wrench with an enclosed opening that grips the faces of the bolt or nut.

SCREW DRIVERS. A device specifically designed to insert and tighten, or to loosen and remove, screws. Types of screw drivers are classified according to its tip such as Slotted, Phillips, Pozidriv, Torx, Hex, Robertson, Tri-Wing, Torq-Set, and Spanner.

HAMMERS . A tool meant to deliver blows to a target, causing it to move or deform. The most common uses are for driving nails, fitting parts, and breaking up objects. Industrial hammers can be classified into three types; [1] Claw Hammer, a tool primarily used for pounding nails into, or extracting nails from, some other object. [2] Ball-Peen Hammer, the original function of this hammer was to "peen" riveted or welded material so that it will exhibit the same elastic behavior as the surrounding material. [3] Mallet, hammers with heads made of softer materials than the steel normally used in hammerheads, so as to avoid damaging a delicate surface.

PLIERS . Are hand tools, designed primarily for gripping objects by using leverage and numerous different jaw configurations to grip, turn, pull, cut or crimp a variety of things. Types of pliers includes; [1]Flat nose pliers, also known as "duckbill," after their resemblance to a duck's bill. With long,

narrow, flat jaws use for holding and gripping. [2] Long-nose, also called "needle nose pliers", which have long, narrow jaws for gripping in confined spaces.[3] Diagonal Pliers, such as wire cutters, side cutting pliers or side cutters, are not really pliers as it is only used for cutting.

In using hand tools, one must also know the basic Safety Tips

1. Know the purpose of each tool you use, and use each for the specific task it was designed to do.

2. Never use any tool, hand or power tool unless you are trained to do so and are familiar with its use.

3. If you have a question about hand tool usage, ask someone who know.

4. Inspect tools before each use and repair or replace if worn or damaged.

5. Clean tools after every use.

6. Keep cutting edges sharp.

7. Never test a cutting edge with your fingers, test on a scrap material instead.

8. Select the right size tool for the job, don't use cheater bars.

9. When working on ladders or scaffolding, be sure that you your tools are secure. A falling tool can seriously injure a co-worker or bystander.

10. Carry tools correctly, never put sharp or pointed tools in your pockets.

11. When hand-carrying sharp tools, point cutting edges away from you, toward the ground or cover the sharp edges.

12. Wear Personal Protective Equipment (PPE) such as safety glasses, safety goggles, face shields, gloves and proper clothing as appropriate.

If a tool is defective, remove it from service, and tag it clearly "Out of service for repair". Replace damaged tools immediately and do not use defective tools "temporarily". Have tools repaired by a qualified person and do not attempt field repairs.
