Tool Identificationand Use
Where do you buy tools?
Dealers• Snap-On• MacRetail Stores• Canadian Tire• Wal-Mart
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
HammersBall Peen• Used for general striking
work• One rounded striking face• One flat striking face• Available in a range of sizes
from a few ounces to several pounds
HammersSledge Hammer• Large flat head• Made of metal• Able to distribute force over
a wide area
HammersBrass Hammer• Used to prevent marring
the work surface being struck
• Head made out of brass
HammersPlastic Tip Hammer• Used to prevent marring
the work surface being struck
• Similar to brass hammer, but plastic is an even softer material
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
ChiselsUsing a chisel holder protects your hands
when striking with a hammer Chisel Holder
PunchesStarting Punch• Has a tapper that ends with
a flat tip• Used for driving out rivets
after the heads have been cut off
PunchesDrift Punch• Has the same diameter for
the majority of its length • Used for driving out rivets
after the starting punch
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
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 Common File Types• Flat Mill• Half-Round• Round• Square• Triangular
All file types come in different sizes and with cutting edges that range
from coarse to fine.
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
FilesRotary Files• Come in a selection of shapes and sizes• Designed to be used in a hand drill or hand held air
grinder
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
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
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
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
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
Reamers• Some reamers are a fixed size, some are adjustable• Tapered reamers are good for removing burrs and for
starting taps
