Rockwell-RK5132K Review Summary:

The Rockwell RK5132K is a powerhouse oscillating tool suitable for price-savvy tradesmen and DIYers. It’s a complete package that includes the multi-tool, accessories, and a carry bag to get on the job right away.

Equipped with a 3.5-amp motor that delivers up to 20,000 OPM (oscillations per minute), this device is built to withstand heavy load. And its six-step variable speed dial offers control for various applications.

The RK5132K sports a sleek design that fits snugly, even for folks with smaller hands. Plus, it’s only 2.9 pounds and features a 10-foot cord, which offers you a degree of freedom from the mains outlet.

Also, the universal fit system allows this multi-tool to accept accessories from most popular brands. And, it employs a tool-less blade change system that locks accessories with 1-ton of holding force — ensuring zero blade movement.

Rockwell Tools, a subsidiary of Positec Tools, is known for manufacturing power and hand tools capable of professional and private use. In fact, their Sonicrafter — an older version of the RK5132K — was named Product of the Year by DIY Week in 2011.

The 3-year limited warranty shows it’s still in contention as a reliable product.

Features and Benefits of Rockwell RK5132K Oscillating Tool

Now that you’ve been introduced to the RK5132K, aka Sonicrafter F30, let’s delve deeper into its capabilities.

Durable Work-Hungry Motor

The Rockwell RK315K has a 3.5 amp motor that raves on under pressure.

With a thirty-four-pound stall force, you can exert abnormal pressure during operation, and the motor won’t fail you — it will maintain its speed.

In addition to its torque, it boasts a 20,000 OPM max speed that would make easy work of sawing through wood, scraping grout, cutting PVC pipes, and shearing off nails. What’s more, with the appropriate blade mounted, it can cut metal sheets smoothly.

Easy-to-Handle Design

Any designer knows weight and portability are the hallmarks of convenient oscillating tools. And, the Sonicrafter F30 represents these qualities.

Opening the field, weighing only 2.9 pounds, it’s considerably lighter than comparable 3.5-amp oscillating tools. Even an ounce extra would accelerate arm fatigue. So if you’re using the RK5132K for any length of time, you’d rapidly appreciate this feature.

Scoring the touchdown, it bears a 10-foot cord that would cover an average-sized room without the requirements of an extension lead. In short, although it’s corded, the cable restraints are more forgiving with this multi-tool.

Universal Blade Interface

Equipped with a Universal Fit System blade interface, the Rockwell accepts blades and accessories from most major brands — meaning you’re not tied down to a sole manufacturer’s attachments. Plus, it allows you to position blades to a convenient angle for your work.

What’s more, its Hyperlock blade change mechanism is tool-less and stress-free. It only requires you to loosen and screw the clamp tighter to remove or mount blades. Honestly, it’s a lot better than changing blades with an Allen key — plus, digging around to find one.

And, while it’s a somewhat old-fashioned technology, it delivers literally a ton of holding force. This means your attachment won’t stray from its position, thus your cuts will be precise.

Variable Speed Control

The on/off switch is located just below the Hyperlock, which provides you with centralized control of the tool. To change operating pace, the RK5132K uses a dial with six-speed levels. It adjusts with the range of 11,000 OPM to 20,000 at top speed.

Even better, as it operates using set speeds, it allows you to focus on handling the tool — unlike multi-tools with a paddle trigger.

However, whether using a trigger or set speed control, it does mean you can tailor your tool to the application. Let’s face it, it’s not all about fast and furious oscillating action — some surfaces require a slow and steady approach. And this multi-tool can deliver that light touch or forceful speed — as your task requires.

What Users Say About The Rockwell RK5132K

The Rockwell RK5132K appears to be a value for money multi-tool that offers solid performance for the DIY enthusiast or the tradesman seeking a secondary device.
Okay, enough of my views. Let’s read the misguided, neutral third-party opinions from customers.

Users cherish its speed and torque in operation. The RK5132K performs an almost endless list of tasks exceptionally — with suitable blades. Owners of this unit also praise the rigidity and safety of its blade change system — welcoming the firm attachment grip.

What’s more, the majority also appreciate that the Sonicrafter F30 is lightweight and easy to operate — admiring how they can handle it for longer periods before tiring.

The accessory kit is another valued addition, because most can work with the tool straight away. However, some felt the included blades were flimsy, and they’d have to buy new ones with a befitting quality.

Alternatives to Rockwell F30 Oscillating Tool

While the RK5132K is a rugged powerhouse, perhaps it’s not quite ticking all your multi-tool boxes. Here are three alternatives worthy of further consideration.

If you love the Rockwell but deep down you’re a cordless tool fanatic, take a look at the DeWalt DCS356B.

Although it reaches the same top speed as the RK F30 Sonicrafter, its variable pace is controlled by a three-stage selector — with speeds between 13,000 to 20,000 OPM.

And, unlike the RK5132K, it doesn’t come with a 32-piece accessory kit. But it is equipped with LED light, dual-grip, and a faster tool-less blade change system.

  • Both have a top speed of 20,000 OPM.
  • The DCS356B comes with a slightly higher price tag.
  • With an oscillating angle of 3 degrees, the DeWalt has a less aggressive angle, compared to 4 degrees of the Rockwell.

If you’re only an occasional tool user and want an even more budget-friendly option, the Galax Pro 22000 could be a solution.

Sporting a 3.5-amp motor with a variable speed and power-focused four-degree cutting angle. It also features a rotating side handlebar to reduce vibration, a 30-piece accessory kit, and like the RK5312K, a six-speed operation dial.

  • Faster operating speed — runs at 22,000 OPM compared to Rockwell RK5132K’s 20,000 OPM.
  • Unlike the Rockwell, the Galax comes with a side handlebar.
  • It’s lighter on the pocket than the RK5132K.

The Bosch GOP40-30B is ideal if you’re looking for more grunt and a wider range of oscillating speeds.

Arriving with a 4.0-amp motor and a more personalized variable speed dial of 8,000 to 20,000 OPM. It also features a snap-in no-touch accessory system that’s considered one of the fastest and easiest to use on the market.

  • The Bosch is considerably more expensive, compared to the Rockwell.
  • Slightly more powerful motor — 4 amps compared to the RK5132K’s 3.5 amps.
  • Both feature a tool-less accessory change system.


Oscillating tools are becoming increasingly popular among handymen, professionals, and even amateurs. And there’s no better reason for this upsurge than their versatility. These small angle-grinder-like machines can reach tight spots and accept accessories that perform the jobs of several power tools. And they don’t have to cost a fortune.

So, it’s not so hard to see why the Rockwell RK5132K Sonicrafter F30 enjoys a large following. It’s lightweight and has a lengthy cord that lets an operator work conveniently. More noticeably, it sports a force that waltzes through flash cutting, grinding, sanding, plunge-cutting, and other tasks it faces.

Also, it’s a smart choice for workspace use because of its no-touch accessory change system, one-ton holding force, and dial-controlled variable speed.

While it does lack an LED light, as we’ve seen, the multi-tool essentials are present — offering value for money. So go check out the Rockwell RK5132K and see for yourself.
