Which of the following statements about drill bits is not true?
drill bits are primarily right-handed |
|
drill bits are primarily left-handed |
|
drill bit size maxes out at ½" for metalworking |
|
drill bit size maxes out at ¼" for woodworking |
Drill bits remove material to create holes. They come in a variety of sizes, maxing out at ¼" for woodworking and ½" for metalworking. The majority of drill bits are right-handed which means they cut while rotating in a clockwise direction.
Inside and outside micrometers measure inside and outside:
tolerances |
|
lengths |
|
diameters |
|
angles |
Micrometers measure the diameter of cylindrical objects. Outside micrometers measure the external diameter of cylinders and inside micrometers measure the internal diameter of the cylinder's hole.
Which of the following determines whether a socket can be used with a particular ratchet?
the drive size |
|
the socket size |
|
the point size |
|
the drive circumference |
A ratchet (or socket wrench) is a wrench that applies torque in only one direction with a handle that can be moved back and forth without losing contact with the fastener. A ratchet uses variable attachments called sockets which come in a variety of drive sizes based on the size of the opening that attaches to the ratchet. Sockets with the same drive size will vary in the shape (six-point, twelve-point) and size of the nut opening that attaches to the fastener being tightened or loosened. Smaller point sized sockets are stronger and can apply greater torque while larger point sizes allow easier alignment.
Which of the following tools are you more likely to use when woodworking?
rivet |
|
chisel |
|
wrench |
|
punch |
A chisel has a long sharp edge and is used, often in conjunction with a hammer, for cutting. In woodworking, chisels are used to remove large sections of wood to create the initial shape of a design. In metalworking, chisels are used to remove waste metal when a smooth finish is not required.
A welding rod provides:
stability for the welding torch |
|
protection for the welder |
|
the joining material for a weld |
|
fuel for the welding torch |
The joining material for a weld is called a welding or filler rod and is available in a variety of diameters and alloys for different welding tasks.
