Tools & Equipment Flashcards

What safety feature on many circular saws stops the blade rapidly when the trigger is released?

Answer: Electric brake

An electric brake briefly reverses current to the motor when the trigger is released, stopping blade rotation quickly to reduce the risk of contact injuries.

Before operating a keyed chuck drill, which step is absolutely required?

Answer: Remove the chuck key from the chuck

The chuck key must always be removed before starting the drill; a key left in the rotating chuck becomes a dangerous projectile that can cause serious injury.

What is the function of the spiral flutes on a drill bit?

Answer: To channel chips and debris out of the hole

The spiral flutes create a helical channel that carries chips and debris out of the hole as the bit advances, preventing clogging, overheating, and bit breakage.

Under what circumstance is it acceptable to remove the guard from an angle grinder?

Answer: Never — the guard must always remain installed

Angle grinder guards must never be removed because they protect operators from sparks, debris, and the hazard of disc fragmentation at high RPM.

Which power saw is best suited for making curved or irregular cuts in wood or thin materials?

Answer: Jigsaw

A jigsaw uses a short, narrow reciprocating blade that can pivot and navigate curves, making it the correct tool for curved or irregular cuts.

What role does the pilot bearing on a router bit serve?

Answer: It rides along the workpiece edge to guide and control the cut depth

The pilot bearing rolls along the edge of the workpiece, guiding the router bit and ensuring a consistent profile cut without requiring a separate fence or guide.

When operating a belt sander on wood, in which direction should you move the tool to minimize surface scratches?

Answer: With the grain to reduce visible scratch marks

Sanding with the wood grain keeps any scratch marks parallel to the grain lines, making them far less visible in the finished surface.
