Drill bits are cutting tool
s used to create cylindrical
holes, almost always of
circular cross-section.
Drill bits come in many sizes
and have many uses. Bits are
usually connected to a mechanism,
often simply referred to as a drill,
which rotates them and provides
torque and axial force to create
the hole.
A drill bit is a cutting tool that's
fitted into a power drill and used
to cut holes in materials.
They come in a wide variety
of shapes and sizes, but they
all have similar parts as follows:
Point: the top, cone-shaped part
of the drill bit that consists of
a spur and cutting lip.
A drill bit is the cutting
device located at the end
of a drilling machine's drill string.
Like the bit on a hand-held drill,
it creates a passage through the
material into which it bores.
It may assist — to some extent
— in removing the material
which it cuts away to form
the passage.
A drill is a power too
l that uses a rotating drill bit.
It is used to create holes in
various materials, such as wood
, metal, and plastic. Drills are
commonly used in construction
and carpentry work, as well as
in plumbing and electrical work.
To determine the size of
the drill bit, you need to
calculate the diameter of
the hole that needs drilling.
Drill bits with sizes between
1 mm and 20 mm in diamete
r are the most common drill bits.
The drill hole size should be the
same size as the screw's
central core diameter or
slightly smaller.
