What is the recommended speed to run a grinding wheel? - answer-Never run it faster
that the max RPM of the grinding wheel
How should you start a grinder? - answer-Stand off to the side and wait a full minute
Is 46 or 60 the coarser grit? - answer-46
What are the 2 most commonly used abrasive materials? - answer-Aluminum oxide and
silicone carbide
For what purpose is the diamond dresser used? - answer-When a very fine finish is
required
What is the purpose of ring test? - answer-to check for cracks
If a grinding wheel makes a ringing sound what does that mean? - answer-wheel is not
cracked
What is the purpose of truing a grinding wheel? - answer-Restores the shape of the
wheel and makes the outer surface of the wheel concentric with its bore
An out of balance wheel: - answer-vibrates
Belt grinders are useful for: - answer-quickly deburring and chamfering a workpiece
What is the purpose of a GFCI? - answer-Senses drop in current and switches power off
,The kind of abrasive material use in grinding wheels for general purpose application is: -
answer-aluminum oxide
Is it safe to carry a portable grinder by the power cord? - answer-False
Is it safe to use standard sockets with electric impact wrenches - answer-False
The larger the power drill, the slower the RPMs and the higher the torque - answer-True
Can you use conventional drill bits with a hammer drill? Why or why not? - answer-Yes of
the hammer drill has a switch to turn off hammer action
Most cordless drills have torque control - answer-True
Prolonged use of power or air tools can cause carpal tunnel sydrome - answer-True
Is it safe to run an impact wrench with a universal joint and socket attached - answer-No
because it may throw off attachments
What conditions would you use a GFCI - answer-Wet conditions
What 3 things does a GFCI protect: - answer-1. Overload 2. Overcurrent 3. Ground fault
protection
A GFCI prevents all electrical shocks - answer-False
Higher voltage on a battery means: - answer-Greater power of tool
, What type of power load must be used in the low velocity tool? Why? - answer-Power
load with a crimped end must be used cause high power load would get lodged in the
tool
6 colours ranging from lowest strength to highest strength for power load are: - answer-
1. Grey 2. Brown 3. Green 4. Yellow 5. Red 6. Purple
Power loads should not be carried loosely in pockets or aprons. Why? - answer-Could
be set off causing serious injury or death
Fasteners used in explosive actuated tools are: - answer-Manufactured from special
steel and tempered
A drive pin is a fastener used to: - answer-Permanently attach one material to another
What is base material? - answer-Material which the fastener shank is driven into
To determine the sustainability of a base material, use a fastener as a centre punch
struck by a single average hammer blow. If the fastener is blunted ( meaning it can't
fasten) the material is too: - answer-Hard
To determine the sustainability of a base material, use a fastener as a centre punch
struck by a single average hammer blow. If the fastener penetrates easily, do not fasten
because the material is too: - answer-Soft
To determine the sustainability of a base material, use a fastener as a centre punch
struck by a single average hammer blow. If the material cracks or shatters, do not fasten
because the material is too: - answer-Brittle
A threaded knurled pin is designed for what material - answer-Mild steel
