Plastic Drill Bits
Plastic
drill bits were designed to deal with such
materials as Plexiglas® and Acrylite® along with
other plastics.
It’s entirely
possible that by looking at the title of this
article you may be inclined to think that a new
drill bit has been developed using plastic as
the primary component of construction. However,
when referring to plastic drill bits we are
actually referring to a drill bit specifically
designed to bore through a variety of plastics
while producing a smooth hole.
Many have mistakenly tried to use a standard
wood bit to achieve this goal and wound up with
cracks and jagged edges in their plastic (we’ll
talk more about this later).
A plastic drill bit was designed to deal with
such materials as Plexiglas® and Acrylite® along
with other plastics.
If you are using a plastic drill bit for the
first time it is important to make sure that
when you drill as a guide for an attaching screw
that you make the hole size slightly larger than
the screw to allow for any contractions in the
plastic.
While a standard drill can be used to drill
holes in plastic, a drill bit specifically for
plastics may have best results when a drill
press is used. The primary reason this is true
has to do with the slow even pressure needed to
achieve the smoothest desired result. If you do
need to use a hand drill, be sure to ask which
plastic drill bit may be best to use with this
type of drill.
There are nearly 90 separate drill bits for
applications involving plastic - all an inch or
smaller.
Some experienced handy folk have found that
regular wood drill bits can be used for this
application, but require modification to the
existing drill bit. Small flats must be ground
on each side of the edges that will cut into the
plastic. The speed of the drill must be reduced
to supply gentle, continuous pressure to the
plastic material.
If you’d rather purchase the plastic drill bit
you need simply visit your favorite hardware
store or shop online for the greatest variety
and information.
