What are the types of screwdriver bits?

There are a lot of different shapes of bits on the market and today we will look at what they are. They differ mainly in the type of screw head for which they are intended.

Screwdriver bits are interchangeable ends for screwdrivers and drills that allow you to screw in different types of screws. They are made of different materials (e.g. steel, titanium, tungsten) and have different types of ends depending on the screw head.

The most common types of bits can be found in the following table:

	flat/slotted (SL - slot) - classic straight bit
	cross (PH - Phillips) - classic cross bit
	cross with a slot (PZ - Pozidriv) - for greater grip and stability
	Torx (Tx) - star shape, minimum torque required
	hex (H) - hexagonal bits (hexagon)
	Robertson (R) - square bits

There are also other, less well-known types of bits. These include, for example:

AW, Torx with a hole, XZN (dodecagonal), Tri-wing, Torq-set, five-star, etc.

The bits are further divided into:

1. Standard bits
