STIHL Cordless Power Cutter TSA 350 – AP system is a serious professional cut-off saw built for contractors who need petrol-level cutting ability without the noise, fumes, and maintenance that come with a traditional disc cutter.
Designed around a 350 mm cutting disc with up to 125 mm cutting depth, it’s made for landscaping, construction, civils and site work where clean, precise cuts matter. Run it with the recommended AP 500 S battery and you get a compact cordless machine that’s capable of tackling paving, concrete, steel and general jobsite cutting with proper control.
A Professional Cordless Cut-Off Saw for Site and Construction Work
The STIHL TS350 is built for one job: serious cutting work where a standard grinder or smaller battery cutter won’t touch the sides. It’s aimed squarely at professional users in landscaping, building construction and civil engineering who need proper depth, control and output — but want to step away from petrol machines.
With a 350 mm cutting disc and a maximum cutting depth of 125 mm, it’s designed for kerbs, paving, concrete products, steel sections and general site cutting where accuracy matters as much as power.
Power That’s Intended to Replace Petrol in the Right Applications
STIHL hasn’t positioned the TSA 350 as a lightweight alternative. With up to 3.3 kW electrical power and around 2.8 kW mechanical output, it’s designed to handle many of the jobs traditionally reserved for machines like the TS 420.
To get the full performance from the TSA 350, STIHL recommends running it with the AP 500 S battery. That’s an important detail — this is a high-demand tool, and smaller batteries won’t deliver the same output under load.
Compact Handling and Precise Cutting Control
One of the biggest advantages of the TSA 350 is how controlled it feels for a 14-inch cut-off saw. At 7.3 kg without battery, it stays compact and well balanced, making it easier to guide accurately through cuts rather than wrestling the tool.
The rigid construction and ergonomic handle design help with disc alignment, which reduces wastage when cutting expensive materials or working to tight lines on site.
Constant Power and Power Boost Electronics
Battery cut-off saws live or die by consistency. STIHL’s Constant Power system keeps cutting performance steady as the battery discharges, rather than fading away towards the end of a charge.
The TSA 350 also features Power Boost, where the tool and battery communicate to deliver the maximum available output when the cut demands it. For professional users, that means fewer stalls and less forcing the machine through tough material.
Dust Control and Long Service Life Features
Cutting on site creates dust, debris and metal particles — and that’s what kills motors over time. STIHL has built the TSA 350 with features aimed at long-term durability in harsh environments.
- STIHL Magnetic Filter captures ferromagnetic particles before they reach the motor
- Water connection allows dust suppression and cooling during heavy cutting
- Adjustable magnesium guard improves visibility and directs debris away from the operator
This is the kind of detail that matters if the saw is being used regularly, not just occasionally.
Fast Run-Out Brake for Safer, More Efficient Work
The cutting disc brakes in under 4 seconds once released, which improves safety and keeps work moving. STIHL also uses regenerative braking, feeding recovered energy back into the battery during stopping.
That doesn’t magically double runtime, but it does improve efficiency over a working day.
Runtime Reality and Battery Planning
Like any high-output cordless cut-off saw, runtime depends heavily on what you’re cutting and how hard you’re pushing it. With the recommended AP 500 S battery, working time ranges from around 11 to 20 minutes.
For professional users, the solution is simple: run multiple batteries or rotate packs across a fleet. This isn’t a machine you buy expecting one battery to last all morning — it’s built for high-load cutting where output comes first.
Where the TSA 350 Makes the Most Sense
The TSA 350 is a strong fit for contractors who want a professional 14-inch cut-off saw without petrol drawbacks. It’s particularly useful where emission-free operation matters, including indoor work or noise-sensitive sites.
If your work involves frequent cutting of paving, concrete products, kerbs or steel, and you want cordless convenience without stepping down in capability, the STIHL TSA 350 is one of the most serious battery cut-off saws in STIHL’s AP range.
Support, Servicing and Aftercare from Suffolk Mowers
A professional cut-off saw like the STIHL TSA 350 is an investment, and it’s the sort of machine that earns its keep when it’s backed up properly. Buying through Suffolk Mowers means you’re not just getting a box on a pallet — you’re getting dealer support from people who understand how this kit is used on real sites.
We can advise on the right battery setup, especially as STIHL recommends the AP 500 S to unlock full performance. If you’re already running AP batteries across other tools, we’ll help you build a sensible rotation. If you’re stepping into the system for the first time, we’ll make sure you don’t end up underpowered or short on runtime.
Servicing, Parts and Long-Term Reliability
Cut-off saws live in harsh conditions — dust, grit, metal particles and constant load. Suffolk Mowers can support ongoing maintenance, genuine STIHL parts supply, and servicing to keep the TSA 350 working as it should over the long term.
Warranty and Professional Backup
Purchased through an authorised dealer, the TSA 350 is covered by STIHL’s warranty support. And if you ever need help with setup, accessory choice, cutting discs or general operation, you’ve got a local team who knows the product and the type of work it’s built for.
In short, Suffolk Mowers supports the sale properly — before you buy, while you’re using it, and long after it’s paid for itself on site.
