Concrete core drilling Brisbane is one service
company that rests its business on its unique set of services which consist
mainly of core drilling. At its very basic, core drilling is simply a technical
task of drilling circular holes in reinforced concrete with extreme precision
and speed.
Generally,
these holes are created on various materials that make up walls, floors,
concrete blocks and asphalt in places where these circular holes are needed for
an installation or become a part of a later project.
Some of
the more familiar uses include use their in plumbing, residential cabling, drainage
slab holes in roadways, and in many other uses requiring such cylindrical holes
in structures.
Safety techniques
After
some time doing projects, core drilling experts have devised their own set of
rules and safety standards to avoid risks and hazards that can be encountered
during the course of a simple drilling job.
Also, after
some time in the business, project operators (the ones who do the drilling and
sawing) have formulated its set of precautionary reminders in the execution of
their jobs.
Less water
During
the operation, less water is used on the diamond core bits (the cutting edge of
the equipment). Using little water as possible allows more efficient grinding
down of the concrete surfaces.
Too
much water washes away the grits which prevents the diamond bits from getting
exposed. By this time, the amount of water used has been roughly estimated by
technicians to approximate the consistency of a milky tea.
Right diamonds
The use
of the right diamonds means the correct choice of the diamond type that
correctly matches the application. The main goal is to save both time and
money. Before embarking on the job, a technician will carefully consider the
materials that will be drilled on (concrete, asphalt, floors, walls).
Next,
he will then consider a particular diamond bond specification of the core bits.
With the choice of too soft a bond can prematurely wear away the diamond.
Choosing too hard bonds can drastically increase drilling time.
Reinforced
concrete needs a soft diamond matrix. For softer materials, a hard diamond
matrix can give best results.
Effective pressure
In a concrete core drilling Brisbane operation, it is vitally important to maintain a steady and even
pressure while drilling or cutting away at a material. The proper amount of
pressure (mostly gathered through various experiences and uneven results) will
prolong the life of the core bit.
Using
too little pressure will make the diamond to glaze over. Inconsistent pressure
on the other hand can cause the bit to glaze over as well. at the other end, using too much pressure can
simply overload the drill and can cause damage to either the drill motor or the
core bit, maybe both at the same time.
Speed and power
Setting
the drill motor at the right RPM is essential for efficient grinding and
prevents glazing the diamond segments.
Generally,
smaller diameter core bits require higher RPMs. With regards to power,
underpowered drills will overheat, while overpowered ones will cause increased
abrasion and the glazing of diamond segments.
