Tool Material
What makes a quality tool?• Made of high-strength alloy steel• Light and easy to use• Highly polished – Easy to clean– Comfortable to handle

Handling and Storage
Where and how should you store tools?• Keep tools stored in a roll-type tool cabinet• Remove oil and dirt from tools– Dirt can damage moving parts of tools
• Lightly oil clean tools to prevent rust

HammersSledge Hammer• Large flat head• Made of metal• Able to distribute force over
a wide area
![Page 7: Tool Identification and Use](https://reader031.fdocuments.net/reader031/viewer/2022012919/56816181550346895dd111ba/html5/thumbnails/7.jpg)
HammersBrass Hammer• Used to prevent marring
the work surface being struck
• Head made out of brass
![Page 8: Tool Identification and Use](https://reader031.fdocuments.net/reader031/viewer/2022012919/56816181550346895dd111ba/html5/thumbnails/8.jpg)
HammersPlastic Tip Hammer• Used to prevent marring
the work surface being struck
• Similar to brass hammer, but plastic is an even softer material
![Page 9: Tool Identification and Use](https://reader031.fdocuments.net/reader031/viewer/2022012919/56816181550346895dd111ba/html5/thumbnails/9.jpg)
HammersRubber Mallet• Usually made of solid
rubber• Some Rubber Mallets have
an internal cavity in the head filled with lead shot
• These are called “Dead Blow Mallets” and prevent rebound when striking

Chisels• Come in a variety of sizes and types• Used for cutting bolts and rivets• Can be held in hand or secured with a holder
![Page 11: Tool Identification and Use](https://reader031.fdocuments.net/reader031/viewer/2022012919/56816181550346895dd111ba/html5/thumbnails/11.jpg)

PunchesStarting Punch• Has a tapper that ends with
a flat tip• Used for driving out rivets
after the heads have been cut off
![Page 13: Tool Identification and Use](https://reader031.fdocuments.net/reader031/viewer/2022012919/56816181550346895dd111ba/html5/thumbnails/13.jpg)
PunchesDrift Punch• Has the same diameter for
the majority of its length • Used for driving out rivets
after the starting punch
![Page 14: Tool Identification and Use](https://reader031.fdocuments.net/reader031/viewer/2022012919/56816181550346895dd111ba/html5/thumbnails/14.jpg)
PunchesAligning Punch• Has a long gradual taper
and a finer point than the starting punch
• Used to align corresponding holes
• Punch is pushed through the holes and then pulled upright to align them
![Page 15: Tool Identification and Use](https://reader031.fdocuments.net/reader031/viewer/2022012919/56816181550346895dd111ba/html5/thumbnails/15.jpg)
PunchesCenter Punch• Used to mark materials
before drilling or marking parts
• When used for drilling, a small impression is made in the material to align the drill bit

Files File Cut• Rough to Smooth depends on the
number and size of cutting edges

Files • Files should have a handle firmly attached to the tang
• This allows a firm grip and prevents the tang from piercing the hand

DrillsPower Drills• Operated by compressed air
or electric motors• Either type of power drill uses
a chuck to secure drill bits• 3/8” and ½” are the most
common sizes• This size means the largest
drill bit size the chuck can fit
![Page 21: Tool Identification and Use](https://reader031.fdocuments.net/reader031/viewer/2022012919/56816181550346895dd111ba/html5/thumbnails/21.jpg)
DrillsCordless Drills• Able to fit into tight spots a
power cord or air hose cannot• With the use of adapters they
can be used as screw and nut drivers
• Useful for quickly removing component screws and bolts
![Page 22: Tool Identification and Use](https://reader031.fdocuments.net/reader031/viewer/2022012919/56816181550346895dd111ba/html5/thumbnails/22.jpg)
DrillsDrill Press• Drill motor and chuck are
mounted on a stand• Material to be drilled is
mounted directly below on table
• Drill bit is lowered into work by turning hand lever
• Eliminates the need to hold drill and ensures proper alignment
![Page 23: Tool Identification and Use](https://reader031.fdocuments.net/reader031/viewer/2022012919/56816181550346895dd111ba/html5/thumbnails/23.jpg)
DrillsDrill Press• Can only be used on parts that
will fit on the mounting table• CANNOT be taken to the
vehicle for drilling on a part that cannot be removed

DrillsDrill Bits• “Chucked” in a drill’s chuck• Does the actual cutting when
drilling holes• Available in fractional inch
sizes (standard) or metric• Usually made of either carbon
steel, high-speed steel, and cobalt steel alloys
![Page 25: Tool Identification and Use](https://reader031.fdocuments.net/reader031/viewer/2022012919/56816181550346895dd111ba/html5/thumbnails/25.jpg)
Reamers• Used to enlarge or shape holes• Makes the hole more accurate in size and smoother• NOT be used to make deep metal cuts• Should only cut a few thousandths of an inch at a time
![Page 26: Tool Identification and Use](https://reader031.fdocuments.net/reader031/viewer/2022012919/56816181550346895dd111ba/html5/thumbnails/26.jpg)
Reamers• Some reamers are a fixed size, some are adjustable• Tapered reamers are good for removing burrs and for
starting taps
