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
Rockwell RK5100K SoniCrafter tool, 2 cutting blades, 1 sanding pad, 1 hex key, 15 sanding sheets, and a convenient carry bag.

Ideal for use with a wide range of materials, this all-in-one tool makes sanding, cutting, and scraping simple tasks.

3.0 out of 5 stars Poor Customer Service, mediocre long-term quality, October 30, 2009

By 

Stormrider "Doug" (Seattle WA) - See all my reviews

This review is from: Rockwell RK5100K SoniCrafter 21-Piece Kit (Tools & Home Improvement)

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 to say I did not.

In brief my problems have been as follows:

1. The Allen Screw that secures the blades now vibrates loose, as a consequence I had to stop to re-tighten the blades every few minutes.
2. The front end gets VERY hot. I mean hot enough you can't hold it! It will deform thin plastic sheeting such as the vapor barrier on wall insulation.
3. The blades are very poorly made. They dulled quickly. I don't know what kind of blades they use for the demonstration videos, but it certainly is not the same as what they sent me. Certainly the nails they show the unit cutting must all be cheap non-ferrous metals.
4. The owners manual that came with the unit must have been written by someone for whom English is a second language.

Supposedly there is a two year warranty on the product. Good luck getting Rockwell to honor that. They essentially have no customer support to whom you can talk to get a RMA number or arrange a replacement.

As a result, my unit is now an expensive paperweight. It does have one useful purpose. I show it to my friends and associates to let them use it if they are thinking of buying one. After using it no one I know wants anything to do with this product.

I ended up buying a Fein Multimaster. More expensive? Certainly. But I only had to buy it once, and it works as advertised. You do in fact get what you pay for.

In summary. Initially the Sonicrafter worked as advertised, but it did not hold up to long term use over a 3 month period. My personal feeling is that the high heat generated by this tool coupled with the high frequency oscillations were more than the cheap materials used in building it could stand when used over time. This may work for a hobbyist making wooden models. but for serious work, it just did not stand up. Customer service was oriented at making sure the customer has no way to actually exercise his right to use the Warrenty.

5.0 out of 5 stars Rockwell Quality [yes variable speeds], December 3, 2008

By 

Mr. Geweke (Tucson Az US) - See all my reviews

This review is from: Rockwell RK5100K SoniCrafter 21-Piece Kit (Tools & Home Improvement)

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 bike.

Since the basic Rockwell is only $20 more than the Dremel and the extra blades are about the same price, there was no question about going for the quality/durability of a Rockwell.

The only convenience problem that I can foresee is getting replacement blades:
Dremel is carried by big box hardware stores; hobbyists who do crafts on the spur of the moment and do not need to rip open walls, will appreciate the around-the-corner convenience.
Rockwell is carried by speciality woodworking stores or the internet; the Home Proj. kind of guys have to plan ahead before ripping into a wall for remodeling. So ordering parts in advance should be a no brainer.

I also really liked the Rockwell case, it is created with niches and screw-downs to hold lots of blades/attachments in place.

I looked at the Bosch 12v battery operated version, and that would have been a good choice but I do not want to have numerous 18v tool systems and chargers for the various power hand tools that I use. I read that the Bosch delivers 20 min of battery power and I might need more time than that between charges.

All four tools mentioned above have variable speeds pretty much the same: 10,000 - 21,000 opm. The Bosch details that I read boasted of 5,000 - 20,000 opm, but I do not know if I need to go that slow. If I did I would have researched more into the rare Praxon version of oscillating tool, which is reportedly underpowered and equivalent to size and weight of the Dremel.

3.0 out of 5 stars rinthesun, December 2, 2008

(REAL NAME)   

This review is from: Rockwell RK5100K SoniCrafter 21-Piece Kit (Tools & Home Improvement)

I purchased this unit 2 weeks ago. Take note, this version, $119.95, does not have variable speed.

Fein's patent ran out, so that is why we are now seeing some competition. The Dremel version does not have a blade that will cut nails which is also true of the Multitool ($59.95) from Harbor Frieght. The Rockwell claims it has a blade that will cut nails a useful feature if you are disassembly something with nails or screws like a countertop.

All of the competition uses a bolt to attach the blades which must be tighten properly for the blades not to fall off. The new Fein units have a new patented blade attachment system that is pretty fool proof.

So for home use I would recommend the Rockwell over the Dremel until Dremel brings out a nail cutting blade. If money is not an object buy the Fein Multimaster.
