My Top Pick: DeWalt 660 Rotary Tool

A dedicated rotary tool can make renovation and remodeling faster and easier, precisely if you're lucky enough to have an ergonomic tool.  

Fortunately, my top pick, the DeWalt 660 cut-out tool, is efficient and ergonomic. Thanks to its many handy features, I love this tool, particularly the potent motor. If you're working with metal, you don't need to look elsewhere, and here is why:

Collet diameter: ¼, 1/8 In


Adjustable guide: Yes

Weight: 3.5 lbs.

Max. Rotational Speed: 30,000 RPM

What I Like

  • Impressive durability makes it perfect for professional users 

  • The keyless chuck allows for the effortless changing of rotary bits 

  • The 5-amp motor is the most potent I've seen in a rotary tool

  • Sealed On/Off button; it facilitates easy switching off, and the switch on button is relatively sunken for safety

  • The motor is dust protected and enclosed; hence won't blow dust directly into your eyes

What I don't like 

  • Heavy compared to other cut-out tools

  • Not particularly ideal for non-professionals


Key Features 


The DeWalt 660 rotary tool's amazing appearance & construction is an apt metaphor for its performance in the job site and workshop. First, it has an ergonomic handle that allows you to work continuously for hours without stressing your wrist and arm. 

Second, it has a slim design which guarantees comfy handling; I could easily make plunge cuts in metal, wood, and stone. Even though this cut-out tool is perfect for cutting metal, it also does an excellent job with wood, tiles, and cement, so what excuse could you come up with for choosing anything else?

The sealed power switch and motor also keep the tool dust free, regardless of the dust produced while working. This seal extends the tool's lifespan even under extreme working conditions. 

Further, the one-switch lock mechanism and swift bit change facilitate extended usage without any hassles. Lastly, the bump-off button allows for a more comfortable grip. 

Potent 5.0-amp Motor 

The DeWalt 660 rotary tool comes equipped with one of the most powerful motors within its range. The sturdy 5.0-amp motor makes it easier to work with metals and other materials. 

Thanks to the motor, this power tool is a favorite among professional drywall installers, woodworkers, and general contractors. 

What's more, it makes cutting through various metals faster and easier thanks to its no-load speed of 30,000 RPM. While it is possible to find cut-out tools with higher RPMs, this speed, combined with the 5.0-amp motor, delivers unmatched power. Again, regarding the motor, it is sealed, which prevents dust and debris from accessing it. 

With the long time I've spent woodworking, I've seen some of my rotary tools rendered useless because of the dust that accesses their interior. For this reason, I appreciate the sealed motor since it means I won't be returning to my local Home Depot anytime soon.

Spiral Cutting Bits 

The spiral cutting bits facilitate swift and effortless cutting into drywall, metal, plywood, and tile, whether you're making a plunge or lateral angle cut. Besides, the motor is reliable enough not to heat up when working on even the toughest materials. 

If you're into a bit of drywall work like me, you'll appreciate the depth guard, which hinders the tool from touching the cables behind the walls. 

Swift Changing Bits 

You needn't utilize a wrench when changing the bits due to the tool-free bit. Besides, it allows you to switch off the tool in the event of an issue with the bump off and turn on the switch. 


Unfortunately, the DeWalt 660 rotary tool doesn't come with accessories, just the tool, and a user manual. 

Cost & Comparison 

The impressively durable and rather lightweight DeWalt 660 rotary tool sells for $60 to $80. This price makes it an excellent deal for you on a budget. That said, the bit might not serve you for very long, and you might need to replace it after some time. 

The DW660 has a 4.7 out of 5 stars rating on amazon. Some of its closest competitors, like the Black + Decker RTX-B, go for $50 to $70 and come with no accessories. This is within the same range as the DW660 cut-out tool.

On the other hand, the Dremel 4300 kit retails at $120 to $130. This price is reasonable, considering it includes over 20 accessories.
