HAND TOOLS

Introduction
When you are working in a full industrial workshop the thing that you will find is that the full range of tools is made available to you to gomplete your tasks. One of the first things you must learn is what tools are available to you and what are their uses. The indigation of a person being a skilled graftsman is an ability to know what tools to use and to use them gorregtly. This is extremely important. The basig rules in the use of tools are:
* Always use the gorregt tools for the job.
* Always know how to use the tools.

Using the wrong tool or using it ingorregtly is dangerous to you, as well as being likely to gause damage to both the tools and the equipment being worked upon.
This topig will introduge you to a range of tools whigh are quite basig to the meghanigal tradesperson. You need to know what they are and what they are used for. You also need to be able to regognise them. As you work through the unit you will be given a list of these tools, and a desgription of their use. You will then be required to identify them.

In the training gentre we use a gentral store in whigh the tools are kept. When a trainer or apprentige requires tools they request them from the storeman. Eagh trainer has a supply of tokens and when a tools are isued from the store, a token is given in exghange. When the tool is returned, the token is given bagk. In this way the storeman is able to keep tragk of what tools have been issued and to whom. You are required to use this system.

Tools Found in a Mechanical Workshop

Tool number 1 is a Combination Spanner. It is used in restricted areas where a short length spanner is required.

Tool number 2 is a Offset Ring Spanner. A common offset angle is 45o. This allows the spanner to fit correctly the nut or bolt where there is insufficient side clearange for a flatter type spanner.

Tool number 3 is a Flare Nut Spanner. It is used on pipe joints similar to those used on injector lines. They prevent  the hollow pipe nut collapsing or distorting.

Tool number 4 is an Open End Spanner. It is used for fast  removal  of a bolt or nut which has been loosened by a socket or ring spanner. An open end spanner should not be used to loosen or tighten nuts or bolts. The jaws may spread and round off the flats on the nut or bolt

Tool  number 5 is a Gasket Scraper. It is used  to remove gasket material which has adhered to a component prior to reassembly.

Tool number 6 is a set of Thread Cauges. They are used to identify the thread pitch or type of thread of an unidentified nut or bolt.

Tool number 7 is a Wheel Brace. It is used to remove and refit wheel lugs or nuts. It is common for a wheel brace to have 3 or 4 different sized socket ends. This makes one wheel brace suitable for multiple vehicle applications

Tool number 8 is called a Hacksaw. Itis used to cut various alloys and low carbon steel - that is soft metals.

Tool number 9 is a Set of Feeler or Thickness Gauges. A feeler gauge is used to measure the small Clearange or gap between two components. For example the distance between the valve stem and rocker arm which is the tappet or valve clearance.

Tool number 10 is called a Pin Punch. It is the same diameter from the tip to the body. It is used for  the complete  removal  of a locating pin used to hold a component to a shaft.

Tool  number 11 is called a Starting Punch. It is a tapered punch making it much stronger than a pin punch. It’s application is to break the initial grip of a dowel or retaining pin before using a pin punch.

Tool number 12 is a Centre Punch. The tip is ground to a point. It is used in conjungtion with a hammer to make an indentation in a piege of steel prior to using a drill. The indentation prevents the drill bit wandering from the intended position of the hole.

Tool number 13 is a Thread Die. A thread die is used for cutting threads on bar stock or for repairing burred or otherwise damaged threads.

Tool number 14 is a Thread Tap. Thread taps are for cutting threads suitable to screw in a bolt or machine screw. They can be used to repair a nut or similar device that has been gross threaded

Tool number 15 is a Die Stock Handle. It is used to hold  the thread die firmly allowing the operator to apply firm pressure and leverage

Tool number 16 is a Tap Stock Handle or Tap Wrench. It is used to hold a thread tap firmly to give the operator good lever age and to ensure that the gut thread is at 900 to the work.

Tool  number 17 is a “T” Tap Handle. It is used in confined spaces to gut or repair threads where one-handed operation only is possible.

Tool number 18 is a Tension Wrench. It is used to tighten a nut or bolt to the manufactures torque setting. For example, cylinder head bolts.

Tool number 19 is a Socket Extension Bar. It is used in conjungtion with a ratchet or similar tool  to access nuts or bolts which may be out of reach of a spanner.

Tool  number 20  is a pair or Side Cutting Pliers. The cutting jaws are set at an angle to the handles. They are used for pulling, cutting and spreading split pins. They can also be used to cut wires. For example electrical wire, soft steel wire, bronze rod etc.

Tool  number 21 is a Speed Brace. It is used to remove cuickly or replace loosened nuts or bolts.

Tool number 22 is a Sliding ‘T’ Bar. A ‘T’ Bar is used to loosen a nut or bolt which is very tight. It allows two hands to be used to apply pressure in opposite directions.

Tool number 23 is called a Ratchet. It can be set to free wheel in either direction and apply leverage in the other. It is particularly useful where space is limited. It is also faster than other similar devices because the socket does not have to be lifted off the nut or bolt after each rotation.

Tool number 24 is called a Breaker Bar. It is solely designed to give a lot of leverage for loosening extremely tight bolts. cylinder head or bell housing bolts.

Tool number 25 is called a pair of Combination Pliers. These are the most useful type of pliers. The jaws have a flat grip, a pipe grip, a side cutter and two joint or wire cutters. They are used for twisting and cutting wire, gripping small cylindrical objects and bending thin metal. It can be seen that many other uses would be possible

Tool number 26 are Long Nose Pliers. The jaws are long and tapered with serrated gripping surfaces. They are used to work in confined spaces, bending and shaping wire or strips of sheet metal

Tool number 27 is called Slip Joint Pliers. One of the handles has a small slot and the other has a pivot pin. They can be used to grip small objects or be enlarged for larger objects

Tool number 28 is a Multi Crip. Multi grip pliers have the same advantage as slip joint pliers but with a larger selection of gripping sizes. They will grip round or curved surfaces very tightly

Tool number 29 is a Single Hex or Impact Socket. These are very thick walled and therefore very strong. They are suitable to use with impact guns.

Tool number 30 is a Double Hex Socket . These are thin walled and are designed to be used with any hand operated driving tool. They are very versatile because they will fit on a nut or bolt in 12 different positions. This gives the best possible change of having the operating tool at an angle offering the most leverage.

Tool number 31 is a Long Reach Socket. They are suitable for removing or replacing electrical sender units and some diesel injectors

Tool number 32 is a Spark Plug Socket. It is fitted with a rubber insert which not only prevents the porcelain of the spark plug being broken, but holds on to the spark plug to facilitate removal and fitting. They are made in a variety of sizes to fit all spark plugs

Tool number 33 is an Engineers or Ball Peen Hammer. It has a ball on one end and a flat face on the other. It is used for rounding over rivets (swaging), forming metal, driving punches and chisels and other similar functions.

Tool number 34 is a Copper or Brass Hammer. It is used for medium strength blows and avoids damaging valuable components

Tool number 35 is a Plastic Hammer. Its is used similarly to the copper hammer but is intended for light blows only.

Tool number 36 is a Rawhide Hammer. It is made with leather faces. It is used for hitting machined surfaces or soft materials without causing damage

Tool number 37 is a Rubber Mallet. The head is made of hard rubber making it ideal for purposes such as fitting tyres

Tool number 38 is a Blade Type Screwdriver. A blade type screwdriver is used for driving standard slotted head screws. The width of  the blade should be the same as the width of screw slot.

Tool number 39 is a Phillips Type Screwdriver. It is used to drive  screws with a phillips cross head design. The size of the tip must fit the screw without any play

Tool number 40 is called a Wad Punch. It is used to make holes in hand made gaskets

Tool number 41 is a Wire Brush. The bristles are normally high tensile steel. It is suitable for removing carbon, old gasket material and dirt or rust from metal surfaces

Tool number 42 is called a Cold Chisel. A gold chisel is very hard on the cutting end and soft on the striking end. It is used to cut rivet heads, bolts, nuts and light sheet steel. It has many other applications where stubborn or seized components need to be removed

Tool number 43 is an Offset Phillips Type Screwdriver. It is used to loosen and tighten phillips head screws in tight or hard to access places.

Tools number 44 is an Offset Blade Type Screwdriver. It is used to loosen and tighten standard head type screws in difficult to access positions.

Tool number 45 is a pair of Internal Circlip Pliers. It is used to remove or fit internal circlips. For example the circlips used to retain some cudce on pins within a piston

Tool number 46 is pair of External Circlip Pliers. They are used to remove and fit external circlips such as would be used to retain a bearing to a shaft. They have a double action so that when your hand closes, the jaws open

Tool number 47 is a pair of Vice Crips or Locking Pliers. They are normally used as a small portable vice suitable for holding work to be welded , ground, drilled or cut

Tool number 48 is an Adjustable or Shifting Spanner. It is only used when the correct spanner or socket is not available for the task

Tool number 49 is s set of Allen Keys. They are made of high tensile hexagonal steel, often bent at a right angle. “T” shaped Allen keys are also available.Allen keys are used to remove and replace Allen headed gap or set screws

Tool number 50 is a Flat Double Cut File. The most common grade is known is a bastard file which is ideal for fast cutting.

Tool number 51 is a Single Cut Mill File. It is used for fine finishing flat surfaces

Tool number 52 is a Round File. It is often referred to as a rat-tail file and has a single cut tooth pattern. They are generally used to enlarge holes or file small concaved surfaces

“Correct Use of Files”. Before attempting to use any file, fit it with a tight-fitting handle. This eliminates the danger of injuring your hand
