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.
Which of the following statements about an 8-point saw is not true?
an 8-point saw makes a rougher cut than a 6-point saw |

|
an 8-point saw makes a finer cut than a 12-point saw |
|
an 8-point saw has eight teeth per inch |
Saw blades are described by the number of teeth per inch (TPI). The higher the TPI of a saw the finer the cut it will make.
Which of the following is the primary difference between pliers and pincers?
pincers squeeze, pliers cut or pull |

|
pliers are designed for large objects, pincers are designed for small objects |
Pincers provide a mechanical advantage that's used to cut, pinch or pull an object. The force applied to pincers is concentrated to a point or to an edge of the tool which allows pincers to be brought very close to a surface. Pincers are typically used for removing objects from a material to which they've previously been applied, for example, to pull nails from wood.
Which of the following determines whether a socket can be used with a particular ratchet?
the point size |
|
the drive circumference |
|
the drive size |
|
the socket 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.
You've bored a large hole in a piece of wood to insert a doorknob. Which of these tools would you use to smooth the edges of the hole?
