The Rockwell RK5139K Sonicrafter with Hyperlock is three systems in one. Hyperlock makes tool-less blade changes simple and easy with less confusion. The Hyperlock Universal Fit system allows for (1) quick and easy tool-less blade changes, (2) securely tightens blades with up to one ton of clamping force, (3) and accepts other brand blades with its universal fit system. No more searching around or shopping for the proper brand blade. The RK5139K 2.5-Amp Sonicrafter also has variable speed control which allows for precision cuts when tackling detailed jobs or even heavy duty tasks. Its effortless Hyperlock design, and flexibility as a multi-tool, will make it your go-to-tool on the jobsite or around the house. Whether you’re a professional or an avid do-it-yourselfer, the all-in-one and versatile Rockwell RK5139K Sonicrafter with Hyperlock gives you the ability to sand, polish, scrape, and cut a wide variety of materials with easy blade changes. It is an effective tool to help streamline any job tasks. The variable-speed operates with microsonic high-frequency oscillation to produce smooth, safe movements without kickback. Ideal on the job site or around the house, this efficient tool boasts a slim body that makes it ideal for working in confined spaces. It will be your go-to-tool for all your projects like scraping to remove paint, old caulking, rust, stain, polish, or grout. Use it to score ceramic tile, remove and cut carpeting, or sand and polish those hard-to-reach spaces. Easily switch blades with the tool-less Hyperlock to cut wood, thin metals, fiberglass, masonry, plastic, flooring, cement board, and even vinyl siding. It would take various other tools to do what the all-in-one Rockwell Sonicrafter can do in less time, less effort, and less hassle.

Great tool I bought this to replace a Dremel multi-tool and I couldn’t be more satisfied. This Sonicrafter puts the Dremel to shame. It is quieter, more powerful and cuts much quicker. I purchased the Hyperlock model to take advantage of generic cutter heads and it doesn’t disappoint. For the price, I would rate it equal to the more expensive brands of this type of tool.
Great product I have a Fein tool and needed to get another because I have a large crew. I do remodels of kitchen and bathrooms and use the Fein tool on every job but needed another and did not want to pay the price for my crew to abuse so I bought the Rockwell and I hate to say it but I really like the Rockwell better. It accepts all blades and is super easy to change out and cost savings is huge as you know the prime cost of these tools are the various blades etc. Get it.. you won’t regret it!
