What is the main purpose of a center punch before drilling metal?
Drilling A Create a small indentation that helps locate the drill bit B Cool the drill bit C Measure the thickness of the metal D Remove burrs from the hole
A center punch makes a starting mark that helps keep the drill bit from wandering.
A twist drill bit is most commonly used to
Drill Bits A make round holes in material B tighten nuts C cut external threads D smooth a painted surface
A standard twist drill bit is designed primarily to make round holes.
What is a flat file commonly used for?
Files A Removing small amounts of material and smoothing edges B Driving nails C Measuring angles D Holding round stock
Files remove small amounts of material and are commonly used to smooth or shape edges.
Which tool is commonly used with a hammer to cut or shape cold metal?
Metalworking A Cold chisel B Wood rasp C Screwdriver D Try square
A cold chisel is designed for cutting or shaping metal without heating it first.
What is the main purpose of a washer placed under a nut or bolt head?
Fasteners A Spread the load over a larger surface B Cut threads into the bolt C Increase electrical voltage D Measure bolt length
A washer helps distribute clamping force and can protect the surface below the fastener.
What does the pitch of a screw thread describe?
Threads A The spacing between adjacent threads B The length of the wrench needed C The hardness of the screw D The diameter of the screwdriver handle
Thread pitch describes the spacing between successive threads.
What is the main purpose of a wood chisel?

Compared with fine-grit sandpaper, coarse-grit sandpaper generally
Abrasives A removes material faster but leaves deeper scratches B removes less material and leaves a smoother finish C cannot be used on wood D contains no abrasive particles
Coarse abrasive grains cut more aggressively and usually leave a rougher scratch pattern.
Which hammer is commonly used in metalworking for tasks such as peening and shaping metal?
Hammers A Ball-peen hammer B Claw hammer C Rubber mallet only D Sledge file
A ball-peen hammer is a common metalworking hammer used for peening and shaping metal.
Before changing a blade or bit on a portable power tool, the safest first step is usually to
Shop Safety A disconnect the tool from its power source B increase the tool speed C remove eye protection D hold the trigger down
Disconnecting power helps prevent accidental startup.
Why should safety glasses be worn when grinding, drilling, or cutting material?
Shop Safety A To help protect the eyes from flying particles B To reduce tool voltage C To make measurements more accurate D To keep fasteners from loosening
Grinding, drilling, and cutting can throw particles toward the operator, so eye protection is important.
