hacksaw |
|
crosscut saw |
|
ripsaw |
|
back saw |

Which of the following determines whether a socket can be used with a particular ratchet?
the drive circumference |
|
the socket size |
|
the point size |
|
the drive size |
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 statements about drill bits is not true?
drill bits are primarily right-handed |
|
drill bit size maxes out at ¼" for woodworking |
|

|
drill bits are primarily left-handed |
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.

What is a caliper used for?
ensuring that surfaces are level |
|
transferring distances between objects |
|
measuring thickness and irregular shapes |
|
making perfectly vertical lines |
Calipers are similar to micrometers in shape but instead of measuring distances, calipers are used to transfer distances between objects. An outside caliper is used to transfer outside dimensions while an inside caliper is used to transfer inside distances. A vernier caliper is an extremely precise caliper (down to \({1 \over 1000}\) inch) that allows measuring / transferring either inside or outside dimensions.
