Hand Tools

To strip electrical wires and to twist mutliple wires together.

Clifford Earl Fitch, Sr. , an engineer at Ingersoll Rand.

One thing that tradesmen are taught is that you do not depend on the insulation factor of your tool handles to save you from an electrical shock. The fact that tool handles are made of insulating materials is coincidental. The handle material has to be comfortable in the hand, has to be cheap to produce and that it is an insulating material is secondary.All electrical work should be done in the off condition for safety purposes and it does not matter if the handle is an insulating material or not.

Water pump pliers are basically channel lock pliers with large rounded jaws instead of the straight ones. My pair can easily encompass a 4" circle or go down a notch to cover a 3" circle. They are very handy for undoing oil filters in autos and pipe joints on ABS pipe.

An electrician would be one person that would use them.

Calipers are used for measuring small thicknesses and widths, not making holes.

"Outside calipers" look like tongs and could stab through lightweight material, but that is not the primary function.

Drill bits are not universal. You choose the size of the drill bit according to the size of hole you like to make.

Each tool has its own cleaning procedures.

1. Using a wire brush/paint brush/cotton waste thoroughly brush/wipe hand tools.

2. If found rusted/corroded use proper abrasive to rub and remove rust/corrosion.

3. Apply anti-rust/corrosion agents.

4. Insert in proper casings.

5. Input anti moisture substances inside casing to absorb if humidity trapped inside.

6. Keep tool and casing in a dry place.

7. While taking for use brush/wipe out anti-rust/corrosion agents applied earlier to avoid slippage on use hence damage.

8. Try do not touch metal parts with hand to avoid sweat on parts which may cause rusting/corrosion.

9. Use gloves while cleaning hand tools.

10. Ensure cleaning is done every day before keeping it aside.

To eliminate short circuiting, to enable and supply reliable and correctly rated power supply, fool proof handling of connection points and equipments during the time of servicing and maintenance.

A wrench is used to tighten nuts. Socket wrenches are a type of nut driver.

If you don't maintain them , they'll wear and break faster.

If you don't maintain them, they produce poorer results.

Dull cutting tools leaves a chewed-up cut instead of a nice, smooth one as an example.

When you can't use that tool any more, you'll either have to stop working while you go and buy a new tool - which will cost you both time and money.

Or pick a poorer tool and work slower, also costing you time.

Tools that get worn can also be dangerous, both to the user, to the surroundings and to other people around you. A tool that get you damaged will make you miss work, costing you time. A tool that destroys the piece you're working on, or something right nearby will force you to do repairs. That means added work and cost, and again lost time.

A tool that damages someone else can get you sued, or even jailed.

All good reasons to maintain your tools.

Safety is important when handling any tool.
First thing that should be done is to read the manual that comes with the tool kit.
If possible wearing heavy duty gloves and goggles will add to the persons safety.

A small, sharp knife such as a paring knife or a steak knife will often reach deeply enough into the crosshair pattern of the screw's head. However, if the screw is in too tight, you might permanently twist the blade without loosening the screw. So, a pair of vise grips can be used to slightly crush the head of the screw in order to gain a grip. Pliers often just do not give enough grip, and channel locks are often too large and unwieldy for the circumstance.

Cannot be treated as a machine but a lever mechanism.

An Allen wrench, or "hex key" is tool used to turn Allen screws or bolts. They come in various sizes, both SAE and metric, and may be single, or foldable into little sets that look like Swiss Army Knives. The heads are far more unlikely to strip out than Phillips or slotted screws, and are often used in, and included with "assemble it yourself" furniture like Ikea stuff. You just insert the end in the screw and turn. Lefty-loosey-Righty-tighty.

Unfortunately nowadays not many hand or electric tools are made in US. Some companies make their best tools in America, Germany, Mexico or Japan. Of the popular makes almost all Ridgid, Stanley, Crescent, Porter Cable, Black and Decker, and Milwaukee have their cheaper tools made in China. . Tools are made everywhere but in my opinion the best are made in Germany, UK, Switzerland, Sweden, USA, Japan and Mexico I still use a 1985 DeWalt 384 rotary saw made in Mexico, almost every day.

a feeler guage cannot be calibrated, it is made at precise measurements that cannot be changed.

When a feeler guage is out of spec, it is replaced.

hammer

A cold chisel is one made from steel that is then tempered and is able to cut through other metals. Much used by metalworkers and blacksmiths.

They come in different weights and prices but a good Stanley 8 pound sledgehammer sells for aprox $30.

Rather than a screw or bolt head having a single slot to take a screwdriver, a torx screw head system uses a six-pointed star shape, and a screwdriver designed to fit.

high carbon steel

Impact sockets are made of softer metal.
