Drill speeds are almost always measured in revolutions per minute, RPM or revolutions per second, RPS. This term means that the drill makes a complete revolution that many times in the specified time period. 7200 RPM means that it will revolve 7200 times in a minute, or 120 times in a second. Some materials require specific drill speeds in order not to damage them. The limits are usually on the maximum speed.
VSR - acronym meaning Variable Speed Reversible drill
variable speed drill No. The correct answer is: Variable Speed Reversing, meaning it has a switch that lets you run the drill clockwise or counterclockwise, at any speed from 0 RPM to the maximum rated speed for the drill in question.
This variable speed drill is for drilling different diameter chose different speeds. Workpiece material in the drill speed is important.

Most are belt driven and have a step down pulley on the motor and the drill. Changing the groove the belt is in changes the speed of the drill. Small groove on the motor and large on the drill will give you the slowest speed.
VSR on a drill stands for Variable Speed Reversible.
Larger bits require a slower (more power) speed.
You can drill holes in aluminum with a drill as long as you have the proper drill bit. Use a regular drill bit and keep speed moderate.
It is called "Drill Rod"

The speed at which a drill spins can vary depending on the model and type of drill. Generally, drill speeds can range from around 500 RPM (Revolutions Per Minute) for low-speed drills to over 3000 RPM for high-speed drills. Some specialized drills can even exceed 10,000 RPM.
