A brake is a mechanical device that inhibits motion by absorbing energy from a moving system. It is used for slowing or stopping a moving vehicle, wheel, axle, or to prevent its motion, most often accomplished by means of friction.

A drill is a tool used for making round holes or driving fasteners. It is fitted with a drill bit for making holes, or a screwdriver bit for securing fasteners. Historically, they were powered by hand, and later mains power, but cordless battery-powered drills are proliferating due to increased efficiency and ease of use.

Drills are commonly used in woodworking, metalworking, construction, machine tool fabrication, and utility projects. Specially designed versions are made for a surgery, dentistry, miniatures, and other applications.

Pads (also called leg guards) are a type of protective equipment used in a number of sports and serve to protect the legs from the impact of a hard ball, puck, or other object of play travelling at high speed which could otherwise cause injuries to the lower legs. These are used by batters in the sport of cricket, catchers in the sports of baseball and fastpitch softball, and by goaltenders in sports such as ice hockey, ringette, bandy, rinkball, field hockey, rink hockey and box lacrosse.

Semi- is a numerical prefix meaning "half". The prefix alone is often used as an abbreviation when the rest of the word (the thing which half of is being described) is clear from context.
