Random Orbital Sander with anti Vibration Technology that Improves Productivity
and Reduces Feedback vibration by up to 50%

Mark Donovan of
HomeAdditionPlus.com reviews Rockwell's random orbital sander (RK4245K)
with active vibration canceling technology.
A random orbital sander is a
common woodworking tool used for sanding furniture and other finished
surface materials and items. As the name suggests a random orbital sander
has a spinning disk that goes through an irregular orbit as it spins. As a
result, it produces a high quality sanded finish while at the same time
significantly reducing the risk of inadvertent scratches frequently caused
with older sanders. |

Dramatically
Reduced Vibration
What I really found superlative with
the Rockwell RK4245K random orbital sander was its unique active canceling
vibration technology, referred to by Rockwell as VibrafreeTM.
Compared to conventional counterbalancing mechanisms the RK4245K random orbital
sander’s VibrafreeTM
technology reduces vibration by up to 50%. As a result, sanding productivity is
increased by as much as 100%. In addition, feedback vibration to the hand is
dramatically minimized. After using other random orbital sanders for an extended
period of time, I found the vibration feeling lingering in my hands for an hour
or more. This was not the case with Rockwell’s RK4245K random orbital sander.
I also found the RK4245K to be
much quieter than other random orbital sanders that I have used in the past.
Comfortable Palm
Grip
Besides minimal vibration, I also
found the RK4245K random orbital sander’s rubberized palm handle area
comfortable to grip. In addition, the on/off sealed rubber switch was a
fingertip away when holding and operating the sander.
High Power and
Performance
In regards to its sanding performance
I found the RK4245K, with its 5 inch diameter sanding head and 2.7 amp motor
delivering 12,000 orbits per minute, to stand out in its ability to quickly and
efficiently remove material. In addition, with its random 1/8 inch orbital
action it produced smooth swirl-free finishes.
Dust Control
Dust is a major concern for me and
other woodworkers when operating a random orbital sander. I found the RK4245K
to perform extremely well in dust collection. With its cyclonic dust/air
separator, and its dust extraction adapter that can easily be connected to
vacuum cleaners, I found the dust generated by the sander to be well managed and
contained within the RK4245K.
Its bag-less and filter-less
Cyclonic/Dust/Air SeparatorTM
system produces an advanced airflow design that guides and traps dust particles
in the dust collector box while allowing air to easily escape. This unique
dust/air filtering and separation system helps the RK4245K random orbital sander
achieve its high sanding productivity.
Summary Conclusions
I found the Rockwell RK4245K random orbital sander to be an excellent value and
extremely effective tool for the woodworking shop. Combined with its VibrafreeTM
vibration reduction technology, comfortable palm grip, and power, the RK4245K
stands out as a winner in my opinion. With dramatically reduced vibration I was
able to operate it for extended periods of time without leaving my hands buzzing
or tingling afterwards. If you are in the market for a new random orbital sander
then I would suggest taking a look at the Rockwell RK4245K random orbital
sander.
