What are the parts of a drainage auger?

Drain auger reel
	The coil is a tightly coiled spring and makes up the majority of the drain snake. Coils can be of different lengths and diameters for different purposes.
	When purchasing a drain snake, the packaging or product information will indicate the diameter and intended use. It can also give dimensions for pipe diameters on which they can be used. Drainage snakes can range in diameter from 5/16″ to 1/2″ (4-13mm). The smallest are for use in swimming pools, while the largest are for drains.
Drain screw head
	The auger head (sometimes referred to as the "drill gimlet") is the extended part of the spool that sits at the end of the drain snake. This is the part of the tool that is fed into the sewer. Its free spring shape is perfect for grabbing clogs and its tip can push through, pierce and hook clogs.
	Some drain augers have interchangeable heads of various designs. For more information see: What types of auger heads are available for drain snakes?
Drain Auger Handles
	The addition of handles allows the basic drain auger to be used as is rather than with a drum or other types of augers. They come in two different forms: a crank handle or a grip handle.
	Crank handle This is a simple S-shaped tube that fits over the end of the snake and is secured with a thumb screw. The lower end is held with one hand while the upper end is rotated with the other hand.
	Grip handle The grip handles work similarly to the handles, but are integrated into the drain auger. They can be either single or double handled, but the single version will include a piece of tubing that acts as another handle. Ironically, they are sometimes also referred to as crank handles; this is because both varieties work with cranking.
	Both types of handles work reasonably well, however grip handles are more user-friendly and easier to get into smooth rotation. However, handles are cheaper.
Plastic body of the drain auger
	Some augers have a plastic casing that provides a protective barrier between the pipes/fittings and the snake itself. A shroud is commonly used on motorized augers as this type of auger moves faster and can cause more damage.
