Rotorazer Review 2018: Mini Circular Saw
Last updated: November 2017
Let's just get something out of the way...
If the Rotorazer sounds too go to be true - sadly, that's probably because it is.
Basically, this saw has a great marketing team, but the saw itself is useless for anything other than very light material work.
It's also WAY more expensive than some alternative small circular saws.
So, let me save you some time...
If you're interested in the Rotorazer, most likely you'll be much more satisfied with a different mini circular saw.
We have a list of our top Rotorazer alternatives below. They have the same benefits as this saw, but are much better choices.
These alternatives are:
- Small, lightweight, and very manageable.
- Useful for both light work, and more rigorous tasks.
- A much better choice than the Rotorazer.

If you've come across the Rotorazer in TV or Youtube ads, you'll know that it makes some big promises. Supposedly it can replace circular saws, saber saws, jigsaws, and other saws. Our full Rotorazer review is below, but our ratings above should give you an indication of our thoughts.
At the end of the day, this is a mini circular saw with a max cut depth of about 1/2 inches. It won't cut through a 2x4, it'll struggle with a lot of general woodworking cuts, and in general this saw is best suited to a crafts enthusiast who only needs it for light work.
Being a very small circular saw, the Rotorazer does have some benefits. It's very easy and comfortable to use, and also easy to store and move around.
We've also got some suggestions for Rotorazer alternatives at the bottom of this post.
Key Features
As mentioned above, the RotoRazer is a compact saw. It shares numerous features with other compact saws and some that are different. Here is a breakdown of some of the key features.
- 54.8mm (25⁄32 in) diameter blades – The small blade size allows for a smaller base plate, as well as making tighter internal cuts. It also allow for an overall smaller tool.
- Three blades are included – These are three of saw blade - Carbide tipped, high speed steel, diamond grit.
- Small base plate – The small base plate allows for cutting in tighter spaces than a standard circular saw will allow.
- 120 Volt / 360 Watt (3-amp) motor – Although not as stout as other compact saws, 3 amps can get many jobs done
- No-load speed of 4,000 rpm – Other saws have a lower rpm, which means slower blade speeds, which means slower cutting.
- Blade is off set to the left side – This may not seem like a big deal, but really works well for right handers.
- Dust collection port – Dust collection? Yep. This can allow you to use it in an area that you wouldn't normally, such as inside a house with carpet.
- Max. depth of cut at 90 degrees: 1/2”
- Weight – 2.65 pounds
- Retractable blade guard - This is not unusual, except that the guard also acts as the base/shoe of the saw.

Our Opinion: The RotoRazer Review
Now that we've covered the features of the RotoRazer, let's take a more in-depth look at this competitor in the compact saw arena.
Cost/Value: 3/5
The RotoRazer is a pretty expensive tool for what you get. Many a full size circular saw can be purchased for less than the cost of the RotoRazer.
Of course there are some other trade offs when you go for a larger circular saw - heavier, bulkier, louder, and so on. But power saws are primarily made to make cuts, and in terms of cutting capabilities you'll get much more bang for your buck with other circular saws.
The don't even need to be larger circular saws - Checkout the Rockwell RK3441K Versacut or the Black & Decker DBCSS20B. These are both small circular saws, which frankly perform much better than the Rotorazer when all the prices are considered.
Motor: 3/5
A 120 volt 360 watt (3.0 amp) motor powers the RotoRazer. That's a bit smaller than some other compact saws and numerous jig saws.
With that said, it has plenty of power for this little saw. The limiting factor of this saws capabilities won't be lack of power - the general size and functionality of the saw already make its capabilities quite limited, as mentioned above.
So in other words, the power production here is not an issue. This motor will easily handle all of the small jobs for which it's best suited.
Blade: 3/5
At 54.8mm (25⁄32 in) in diameter, the saw blades are not going to cut through a 2 by 4. Heck, they're not going to cut through 3/4” stock.
This limitation puts this saw in the hobby category, or specialty use, such as cutting tile and other thinner materials.
Blades are removed installed with the aid of an arbor locking tab and a wrench.
Shoe/Base: 2/5
The shoe, or base, is actually the plastic blade guard and it cannot be set at a bevel. Nope, you're limited to 90 degree cuts with the RotoRazer.
This once again emphasizes the types of jobs the RotoRazer is best suited for - Simple tasks involving light materials. Light woodworking and general hobbyist arts and crafts is what you should expect this saw to handle.
The base on the Rockwell RK3441K Versacut allows up to a 45 degree bevel cut. It's pretty similar to the Rotorazer in terms of size, weight, and power - but made by a better manufacturer, and generally a more capable power tool.
Body/Frame: 4/5
Most modern day power tools are made primarily of polymer casings and metal structures. The RotoRazer also utilizes this construction format. Polymer parts help keep the weight down, without sacrificing quality.
This is one of the few areas where we can give the Rotorazer close to top marks!
Blade Guard: 3/5
As mentioned above the blade guard is the shoe, or base, of the saw. It can be set to automatically stop at a number of depths and retracts when the saw is pushed down against the material to be cut.
The blade is completely enclosed by the saw's body and guard, so you can't sight on it while making cuts. The RotoRazer does have sighting marks on the guard, but these aren't as easy to use as sighting on the blade itself.
We're big on workshop safety here at Woodwork Boss, so I was happy to see a good solid blade guard on the RotoRazer. The sightings on the guard are a let down though.
Ergonomics: 4/5
Most standard circular saws use a perpendicular motor. The RotoRazer uses an inline motor that is part of the handle.
This allows for a narrow saw and puts the motor weight in the user's hand, instead of cantilevered out from the user's grip. This is much easier on the wrist and provides for less fatigue inducing work.
Ease of Use: 5/5
Being lighter than conventional circular saws, the RotoRazer is easy on the hands and arms. With the blade towards the left side the user can easily sight where the blade is cutting, without having to look over the saw. This makes for more accurate cuts.
Build Quality: 3/5
The RotoRazer is not a known name, made by a known manufacture. Instead, was originally pitched on TV, only available by ordering directly.
Later, the RotoRazor became available through retail outlets. The plastic housing and guard seem more brittle than many other manufacturer's products.
Dust Collection: 1/5
The RotoRazer does have dust collection features.. but honestly, don't even bother with them.
Even on top of the line circular saws (and other types of power saws), dust collection is a real challenge and it's an industry norm for the dust collection on most power saws to be generally poor.
It's the same story with the RotoRazer - there's a dust collection port, but it'll basically catch none of the dust.
Who should use the RotoRazer?
Based upon the limited depth of cut and the lack of making bevel cuts, this not going to be a go to saw for the average woodworker.
On the other hand, this could be a good saw for the hobbyist who is dealing with materials thinner than the 1/2” maximum depth of cut.
Uses for the RotoRazer
This small saw will be limited in doing standard woodworking, but one can cut tile, thin steel, aluminum, copper, wood, plastic. Just mount the correct blade for the material to be cut.
The RotoRazer is also capable of making plunge cuts, same as a standard circular saw, but remember, you're limited to perpendicular cuts with the RotoRazer.
Motor and Blade Location Makes for Ease of Use
Most circular saws use a motor that is perpendicular to the blade, directly driving it. This makes the saw wide, with the motor projecting out in the way of some guides and clamps.
The RotoRazer's inline design makes for a narrow width allowing the saw to slide past clamps and other obstructions when cutting. The motor is housing is the handle, putting the weight within the user's grasp.
The RotoRazer's blade is mounted toward the lift, which easier use by right handers.
Toss in a Carry Case and Go
Being a compact saw, the RotoRazer is easy to haul around. Toss it in a tool case and get going.
It won't take up much room and is light enough to easily haul it where you need to work, as long as the work isn't too thick or stout. A carry comes with the saw.
For the Budget Minded?
No, not really. This tool tends to be pretty pricey - especially when compared to other similar options.
Overall I would say that the Rockwell RK3441K Versacut has more features, is a much better and more capable mini circular saw overall, and offers far more bang for your buck.

Dremel SM20-02
[amazon box="B005JRJE6A" title="Dremel SM20-02" tracking_id="woodworkboss-20"]
As you engage the Dremel SM20-02 (also called the Saw-Max), you really feel its power buzzing through your hand.
Which is surprising, because this is a very small and easy-to-hold saw.
The Dremel is very versatile - cutting through metal, tile, wood, and most other materials you may need to handle during small projects.
The powerful 17,000 RPM motor delivers precise and clean cuts, every time.
This saw is just straight up better than the Rotorazer (and usually cheaper, too)...
The max cutting depth is 3/4" (compared to the Rotorazers 1/2"), and there's also two blade positions - one for straight cuts, and one for plunged cuts.
The Dremel SM20-02 is a quality product, that does exactly what it says on the tin.
It's a lightweight and small saw, with enough power and versatility to deliver precise and wonderfully satisfying cuts.
Hundreds of users in online reviews love it - a truly great mini circular saw.
Genesis GCS545C
[amazon box="B01HF1EQWY" title="Genesis GCS545C" tracking_id="woodworkboss-20"]
This option is a bit beefier...
And by that I mean the Genesis GCS545C is a more capable saw than the Dremel or Rotorazer - It has a larger cutting depth, and also has the ability to cut bevels.
On top of that, you can also get a rip guide to help make long and accurate cuts.
This Genesis saw can handle a variety of materials, and will be particularly useful for wood thanks to its bevel options, and large cutting depth.
It's powerful and delivers crisp, clean cuts.
Even with being a more capable saw, it's still very easy to use...
Being lightweight, it fits very well in the hand - and it's great for getting into those tight spots.
Reviews from users online are very positive. And, you also get some peace of mind with Genesis...
There's a two year warranty, and you can contact their support team in Carolina by phone at any time.
Rockwell RK3441K
[amazon box="B00GTEU0M4" title="Rockwell RK3441K" tracking_id="woodworkboss-20"]
Let me introduce to you, our wood specialist...
When you pick up this saw, you'll be surprised to feel that it only weighs 5lbs. Despite this, the RK3441K and it's 3,500 rpm motor were born to deal with wood.
It'll astonish you by breezing through 2x4's in one pass - and it's perfect for making cut-offs, plunge cuts, and rips.
The Rockwell is super easy to use...
With one hand, it'll help you produce precise and smooth cuts. And, it can also cut bevels at up to 45 degrees.
However, there are some negative reviews from users, which are concerning.
A problem that's been reported a few times is a bolt sheering and the saw breaking, soon after purchase.
This is a really unfortunate issue, because otherwise the saw is a great choice for woodworking.
If that puts you off too much, then consider the Genesis GCS545C (above) instead.
Or you can get the Rockwell, and just be prepared to return it for a replacement if you happen to get a faulty unit.
Conclusion
Unfortunately, the Rotorazer pretty much sucks.
But the silver lining here is that there are several better options, and we've covered a few of them in this article.
The other options are also lightweight and manageable, like the Rotorazer. But, they're more capable, better quality, and usually cost less to boot.
We're sorry to have to disappoint you about the Rotorazer - but, hopefully you found our alternative suggestions useful.
Good luck with your choice, and happy sawing!
If you’ve seen the TV or YouTube ads for this saw, you’ve seen how it’s said to replace almost every saw that a woodworker might have. You know, circular saws, saber saws, tile saws, outlet box saws, etc. With all that it’s claimed to do, we at WoodWork Boss present you one of the best RotoRazer reviews so that you can get the low down on this saw.
I’ve used many a different saw over the years, and I do prefer the lightest and smallest saw to do the job. The RotoRazer is a compact saw and shouldn’t wear your arms out when using it, so it just might fit the bill.
It would be nice to have a tool that could do all the jobs that others do. Once could save a fair amount of money and storage space. The RotoRazer is claimed to do the jobs of many other saws. Let’s take a look and see how it stacks up.

More about the RotoRazer Saw
Now that we’ve covered the features of the RotoRazer, let’s take a more in-depth look at this competitor in the compact saw arena. I’m pretty sure that you’ll find some interesting bits of information.
Cost/Value
The RotoRazer is not an inexpensive tool for what you get. Many a full size circular saw can be purchased for less than the cost of the RotoRazer. Of course, you give up the light weight and compact “foot print.”
Motor
A 120 volt 360 watt (3.0 amp) motor powers the RotoRazer. That’s a bit smaller than some other compact saws and numerous jig saws.
Battery
None included, as this saw uses 120 volts AC.

Additional Features/Accessories
The RotoRazer features a built in dust collector port, allowing for keeping things neat when cutting in a finished house, or in your shop, if it really worked. The collection port is pretty small in diameter and uses a small hose to connect to a shop vac via and adapter.
Using the RotoRazer
Who should use the RotoRazer? – Well, based upon the limited depth of cut and the lack of making bevel cuts, this not going to be a go to saw for the average woodworker. On the other hand, this could be a good saw for the hobbyist who is dealing with materials thinner than the 1/2” maximum depth of cut.

For the Budget Minded? – Not necessarily so, for the price the RotoRazer is limited in performance. Once can buy a couple of more powerful tools for the cost of one RotoRazer.
Pros and Cons
Everything has its ups and downs and the RotoRazer is no exception.
Pros
- Compact size provides for light weight and ability to cut in tight locations
- Dust collector port
- Can cut wood, plastic, metal, tile, and other materials, depending upon blade choice
- Blade is toward the left side allowing for easier use by right handed users
Cons
- Limited depth of cut
- No bevel adjustment
- Blade is not readily visible making tracking cut lines awkward
- Dust collection port and hose are small in diameter, restricting dust collection
- Not a known product name by a known manufacturer
Wrapping It Up
On the RotoRazer web site it’s claimed that this saw will do the job of the following saws:
- Jig Saw
- Circular Saw
- Hand Saw
- Band Saw
- Tile Saw
- Hack Saw
- Miter Saw
Having spent many years in woodworking, I don’t see how the RotoRazer can do the jobs of a band saw or jig saw unless it’s not expected to cut the kind of curves that those two saws can. Nope, I think it can fill in for the other saws, but not those two.
We’re sure that the RotoRazer can serve certain people fairly well, if it’s used with its limitations in mind. Here at WoodWork Boss we’re all about helping you become just that, a WoodWork Boss so we can’t recommend the RotoRazer as a gotta have tool.
