Because the spinning motion produces friction which causes it to heat up!
Normally with a chuck key.
Friction caused the temperature of the recently used drill bit to feel hot to the touch.
When you operate an electric drill, the motor inside converts electrical energy into kinetic energy to rotate the drill bit. This kinetic energy is transferred to the drill bit, allowing it to drill holes into the material.
Friction. When the drill bit is doing its job, cutting the material causes heat and so does the contact of the flue against the walls of the hole.
Use a brand-new bit for metal mounted on a hand drill (not electric). Slowly rotate the bit in the lead, which is a "soft" metal.
In an electric drill, electrical energy from the power source is converted into mechanical energy to rotate the drill bit. This conversion is achieved through the interaction of the electric motor within the drill, which transforms the electrical energy into rotational motion.
An electric drill has a small electric motor inside, driving a series of gears. The power from the gears turn a chuck, which holds the bit placed into it thereby drilling a hole.
An SDS hammer drill is an electric drill that hammers the drill bit in and out slightly as it drills with it. This type of drill is mainly used to make holes in concrete or masonry, and is able to do so easier than a regular drill and bit are.

An electric drill transfers electrical energy from the power source (e.g., battery or outlet) into mechanical energy, which is used to rotate the drill bit and perform work on a material.
She made Holloweenles!
The rotating action of the drill bit makes the hole.
