Which of the following would be used to make a drilling guide mark in a sheet of metal?
chisel |
|
pin punch |
|

A punch is narrow and is used to drive objects like nails (pin punch) or for making guide marks for drilling (center punch) or patterns in wood or metal.
Which of the following statements about drill bits is not true?
drill bits are primarily left-handed |
|
drill bit size maxes out at ¼" for woodworking |
|
drill bits are primarily right-handed |
|
drill bit size maxes out at ½" for metalworking |
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?
measuring thickness and irregular shapes |
|
ensuring that surfaces are level |
|
transferring distances between objects |
|
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.
What is a micrometer used for?
measuring length around corners |
|
measuring the diameter of cylindrical objects with high precision |
|
ensuring that a surface is level |
|
transferring dimensions between objects |
Micrometers provide accuracy to the thousandths of an inch and come in outside and inside varieties. An outside micrometer is used to measure outside thickness, such as the diameter of a bolt, while an inside micrometer is used to measure the inside dimension of an object, such as the diameter of the hole of a nut or the width of a channel.
You're creating a tube out of a sheet of metal. What type of fastener are you likely to use?
rivet |
|
glue |
|
nail |
|
punch |
A nail is a short pin-shaped shaft of steel that's typically used to fasten pieces of wood together. It has a flat head on one end and a point on the other. A rivet consists of a cylindrical shaft with a head on one end and a tail on the other. When the rivet is installed, the tail is expanded and reshaped to form another head, creating a dumbell shape that will hold two surfaces together semi-permanently.
