Microsonic™ high-frequency oscillation provides smooth, safe movement without kickback. View larger. A Complete Workshop in One Versatile Tool
Whether you’re a professional woodworker or an avid do-it-yourselfer, the RK5100K is an effective way to streamline your work. Easily carried in its compact, lightweight bag, the kit can be kept at your fingertips for all your remodeling, installation, and repair projects.

Starting with the basics, the 21-piece multipurpose kit comes with a Sonicrafter tool and includes two cutting blades, a sanding pad, and 15 sanding sheets that help you to make plunge cuts, flush cutting door jams, and sand, with professional-grade results. It also includes a hex key and carry bag.

The kit’s versatile capabilities come in handy when performing multi-duty tasks, such as exposing hardwood flooring. First, the universal end-cut blade easily cuts through thick linoleum. Then, the sanding system takes over, helping you efficiently polish those hard-to-reach spaces.

High-Frequency Oscillation for Smooth, Safe Precision
For the safest and most accurate work, the RK5100K features super high-frequency oscillation technology. This means that instead of rotating, it makes 20,000 back-and-forth oscillations per minute for ultra smooth, efficient results. Because there are no fast-spinning parts or alternating blades, there are no threats of kickback.

Thanks to its advanced design, the RK5100K cuts only hard materials when fitted with a blade attachment. This way, the tool easily cuts heavy-duty materials, while keeping the user’s hands and fingers safe.

The RK5100K can cut wood, thin metals, fiberglass, masonry, plastic, carpet, flooring, cement board, and even vinyl siding.

High Sanding Capacity with Low Dust Levels
For sanding jobs, this tool requires very little downward pressure and delivers great accuracy. And its slim body enhances your sanding capabilities, allowing you to work on edging and corners that are often not possible to reach with other tools. Plus, it affords you quick and easy clean-up, throwing a very low level of dust whether you’re sanding, cutting, or scraping.

Easy Handling with Lightweight Frame and Soft Grip
The RK5100K has magnesium alloy gear housing, making it lightweight enough for extended use and rugged enough for long-term durability. The soft, ergonomic grip offers you optimum comfort and control while you tackle the job at hand.

What’s in the Box

  1. Poor Customer Service, mediocre long-term quality I wish I had, had the opportunity to actually use one of these that had seen extended service before I actually bought one.For the first few months the Sonicrafter worked OK. Then the mediocre workmanship started to show up. I sent numerous emails, and made several phone calls to Rockwell. They never answered or returned any of them. In desperation I called the sales number on the infomercial. The sales rep took all my information and said I would get a call the next day. Needless…

  2. Rockwell Quality [yes variable speeds] OMG, the Rockewell SoniCrafter is great. I was looking for a corded oscillating tool and looked at the Fein Multitasker and blades, but it is just way too expensive to purchase for my needs. So I bought the Dremel and the Rockwell to compare side by side…The $100 Dremel is lighter and a bit smaller but the buzz the motor makes compared to the Rockwell motor [a little bit heavier and slightly bigger] which humms smoothly is like comparing a Vespa scooter to a Victory street…
