Impact Screwdriver or Impact Driver forms part of a masons
or builders toolkit. It can be a hand tool or electric and often comes in a kit
available with interchangeable heads for both screwing and drilling. The impact
driver is used because it is hard wearing creates strong downward force and
therefore allows for efficient drilling of very hard materials such as stone
and concrete or brick and cement. When used as a screw driver, the impact
driver delivers a torque higher than that achieved by hand. Conversely, the
Impact Screwdriver is also essential for loosening hard to remove screws which
are either corroded in place or over-screwed.
How does it work?
The Impact Screwdriver delivers strong rotational downward
force delivered by the inner core that has teeth which turn inside a shaft
creating torque. The outer shaft is often of a heavy metal material to
withstand shock and impact. A manually operated impact screwdriver will have
hammer and screw action.
The Hammer or Impact action is delivered by cam discs which
rotate transforming rotary motion into linear downward motion to continually
drive the drill bit or screw driver forward. The hammer action is actually
created by a pair of crammed discs and a spring-loaded chuck.
The electric version is controlled by a variety of speed
settings for better control.
What does it look like?
An impact screwdriver looks like a traditional screw driver,
with interchangeable heads or bits. An electric version may have a battery
charger to enable it to be cordless. They often have non slip grips and
electric versions are available with different motor power ratings.
Since the impact screwdriver or drill may be used in very
resistant materials, it is imperative to use the correct chucks and drill bits
to avoid accidents or harm. Specific tungsten carbide tips are available for
this purpose.
When using the Impact Driver as a drill, often the drilling
action creates dust, and fine particles which may be harmful. It is important
to consider eye and mouth protection when using these tools for extended
periods.
