If you’ve ever searched “difference between a ring saw and a concrete saw”, chances are you’re standing on site trying to decide which machine will get the job done faster, cleaner, and with less drama.
Auskut has just launched two serious new contenders in this space – the Red Devil Inferno 415 Concrete Saw and the Red Devil Inferno Ring 370 Ring Saw. On paper they look similar. On the job, they’re built for very different cutting problems.
Let’s break it down in plain English:
What Is a Concrete Saw?
A concrete saw (also called a quickcut or handsaw) uses a standard circular diamond blade mounted on a central arbor.
What it’s best at
- Straight cuts in slabs, footpaths, driveways
- General demolition and civil work
- Fast, controlled cuts where depth isn’t extreme
The Inferno 415 Concrete Saw – Built for Real Work
The Red Devil Inferno 415 is Auskut’s heavy-hitting concrete saw designed for contractors who want maximum power without unnecessary complexity.
Key strengths:
- Massive 415mm blade
- 150mm depth of cut on a new blade
- Strong, reliable 2-stroke power
- Ideal for expansion joints, trenching, and slab cutting
This is the saw you grab when you want speed, simplicity, and brute force.
What Is a Ring Saw?
A ring saw uses a ring-shaped blade driven around its outer edge instead of the centre. That design completely changes what’s possible.
What makes a ring saw different?
- No centre arbor blocking the cut
- Can cut much deeper than a standard concrete saw
- Perfect for walls, pipes, openings, and rescue-style cuts
The Inferno Ring 370 – Depth Without the Bulk
The Red Devil Inferno Ring 370 is all about deep cutting in tight or awkward spaces.
Key strengths:
- 270mm depth of cut – nearly double a standard saw
- Ideal for block walls, reinforced concrete, pipe penetrations
- Cuts where a normal blade physically can’t reach*
If the job involves depth first, speed second, this is your weapon.
*On deeper or structural cuts, operators will often start the line with a standard concrete saw (handsaw), then switch to a ring saw once conventional blade depth becomes the limiting factor. This approach combines speed up front with maximum cutting depth where it’s needed.
Ring Saw vs Concrete Saw – Side-by-Side
| Feature | Inferno 415 Concrete Saw | Inferno Ring 370 Ring Saw |
|---|---|---|
| Engine | Air-cooled 2-stroke | Air-cooled 2-stroke |
| Power | 4.8kW (6.5hp) | 4.8kW (6.5hp) |
| Displacement | 93.6cc | 93.6cc |
| Blade Size | 415mm | 370mm ring blade |
| Max Depth of Cut | 150mm | 270mm |
| Blade Speed | 4800rpm | 4800rpm |
| Fuel Tank | 950ml | 950ml |
| Weight | 15.5kg | 15.5kg |
| Best Use | Slabs, straight cuts, demo | Deep wall cuts, openings |
Which One Should You Choose?
Choose the Inferno 415 Concrete Saw if:
- You’re cutting slabs, pavements, roads
- You want fast straight cuts
- Most jobs are under 150mm depth
- You want a simple, rugged daily driver
This is the go-to saw for concreters, landscapers, and civil crews.
Choose the Inferno Ring 370 Ring Saw if:
- You need deep cuts through walls or pipes
- You’re cutting openings in reinforced concrete
- Depth matters more than speed
- A standard blade just won’t reach
This is the problem-solver when a normal concrete saw hits its limit.
Same Power. Different Purpose.
What’s impressive about the Red Devil Inferno range is that both saws share the same brutal 93.6cc engine and 6.5hp output. The difference isn’t power – it’s blade design and application.
That means:
- No compromise on performance
- Just the right tool for the right cut
So, Ring Saw or Concrete Saw?
If you’re still asking “what’s the difference between a ring saw and a concrete saw?” here’s the shortest answer:
Concrete saw = speed and straight cuts.
Ring saw = depth and access where nothing else works.
With the Inferno 415 and Inferno Ring 370, Auskut now covers both ends of the cutting spectrum – from everyday slab work to deep, technical cuts that stop other saws in their tracks.
If you want help matching the right cutting blades or application to either saw, that’s where Auskut really shines. Come see our expert team in-store or contact us.
