STIHL TSA 350 Cordless Cut-Off Machine – 350mm / 14″

STIHL TSA 350 Cordless Cut-Off Machine

The STIHL TSA 350 is a professional battery-powered cut-off machine developed for contractors who need the cutting capacity of a 350mm petrol disc cutter without fuel mixing, pull starting or petrol-engine exhaust emissions.

It accepts a full-size 350mm / 14-inch cutting wheel and provides a maximum cutting depth of 125mm. This makes it suitable for demanding construction, landscaping, groundwork and pipework applications, including cutting concrete, paving, brick, natural stone, reinforced concrete, rebar and steel when fitted with an approved cutting wheel for the material.

The TSA 350 runs from a single battery in the professional STIHL AP System. When paired with the recommended STIHL AP 500 S battery, it provides maximum available performance while remaining compact and well balanced for a machine with this cutting capacity.

Please note: this listing is for the tool-only STIHL TSA 350. A battery and charger are not included unless specifically stated in the product option.

Why Masseys Recommends the STIHL TSA 350

Masseys recommends the TSA 350 to professional users who need the cutting depth of a traditional 350mm cut-off saw but want a simpler single-battery cordless setup.

Its main advantage is the balance it achieves between capacity and portability. It provides a maximum cutting depth of 125mm while requiring only one STIHL AP battery.

This makes it particularly attractive to contractors who already use professional STIHL cordless tools and want to add a full-size cut-off machine without investing in another battery platform.

The instant start is useful for jobs involving frequent short cuts, where repeatedly starting and stopping a petrol machine can become inconvenient. Its low-vibration EC motor also helps the operator follow marked cutting lines accurately, especially when cutting paving, kerbs or finished construction materials.

For maximum cutting performance, Masseys recommends using the TSA 350 with the STIHL AP 500 S battery. For regular professional use, pair it with a suitable rapid charger from our STIHL battery charger range.

Professional 350mm Cutting Capacity

The TSA 350 accepts 350mm or 14-inch cutting wheels with a 20mm bore. With the correct approved wheel fitted, it can achieve a maximum cutting depth of 125mm.

This cutting capacity makes it suitable for substantial paving slabs, kerbs, concrete products, brickwork, pipework and steel sections that may exceed the capacity of a smaller 230mm or 300mm cut-off machine.

The machine is supplied with a 350mm composite resin cutting wheel. For prolonged or intensive masonry and concrete cutting, an appropriate STIHL diamond cutting wheel may provide longer life and more consistent performance.

Always select a cutting wheel that is approved for:

• The STIHL TSA 350
• A 350mm wheel diameter
• A 20mm wheel bore
• The machine’s maximum spindle speed
• The material being cut
• Wet or dry cutting, as applicable

Single-Battery STIHL AP System Power

Unlike the higher-output TSA 500, which requires two AP batteries, the TSA 350 operates from one compatible STIHL AP battery.

The AP 500 S is the recommended battery and should be used to obtain maximum performance from the machine. Its high power delivery allows the TSA 350 to reach a maximum electrical input of 3.3kW.

STIHL quotes a maximum working time of up to approximately 20 minutes with a fully charged AP 500 S. Actual working time will vary according to:

• The material being cut
• The cutting-wheel type and condition
• The depth of cut
• The pressure applied by the operator
• Wet or dry cutting
• Battery temperature and condition
• Ambient operating conditions

Twenty minutes of cutting time should not be interpreted as only twenty minutes on site. Cut-off machines are normally used intermittently, with time spent measuring, marking, positioning materials and moving between cuts.

Professionals carrying out repeated or continuous cutting should consider keeping a second STIHL AP 500 S battery charged and ready.

Constant Power and Power Boost

STIHL Constant Power electronics help the TSA 350 maintain consistent cutting performance as the battery discharges. This prevents the pronounced drop in output that can occur with some cordless tools as the remaining charge falls.

Power Boost allows the machine and a compatible battery to communicate electronically and release the maximum available output for demanding cuts. The system can temporarily regulate performance when required to protect the battery and help maintain its service life.

Together, these systems give the machine a more predictable cutting response throughout the usable battery charge.

Fast-Stop Brake with Energy Recuperation

When the trigger is released, the fast-stop brake brings the cutting wheel to a standstill in less than approximately four seconds.

Energy generated as the wheel slows is fed back into the battery. This recuperation function helps make use of energy that would otherwise be lost during braking and can contribute to the available working time.

The rapid braking response is also useful when repositioning the machine between individual cuts.

Integrated Water Connection

The TSA 350 has an integrated, adjustable water connection for supplying water directly to the cutting area.

When the machine and cutting wheel are approved for wet cutting, water can help:

• Bind some of the dust produced during cutting
• Cool the cutting wheel
• Improve visibility around the cut
• Support more consistent cutting-wheel performance
• Reduce loose dust around the immediate working area

For work away from a convenient mains-water connection, consider the STIHL WSA 40 cordless pressurised water container.

The absence of petrol-engine exhaust does not remove the risks created by silica, masonry or metal dust. Suitable water suppression, extraction, ventilation, respiratory protection and site controls must still be used.

Adjustable Magnesium Guard

The lightweight magnesium cutting-wheel guard can be adjusted to suit the working position.

Its integrated water guide directs water and debris away from the operator while preserving a clear view of the cutting wheel and cutting line. The magnesium construction helps provide durability without adding unnecessary weight to the front of the machine.

Low-Maintenance EC Motor

The brushless EC motor is efficient, quiet-running and requires less routine maintenance than a combustion engine.

There is no petrol to mix, combustion-engine air filter, spark plug, carburettor or pull-start assembly. This reduces routine servicing requirements and removes problems caused by stale fuel or extended storage.

The motor’s smooth operation and low vibration also help the operator guide the wheel accurately through the material.

STIHL Magnetic Filter

Cutting steel and reinforced materials can release fine ferromagnetic particles into the surrounding air.

The TSA 350 uses a removable magnetic filter to capture ferromagnetic dust before it reaches sensitive internal components. The filter can be removed and cleaned, helping protect the motor and support consistent long-term performance.

It should be inspected and cleaned regularly when the machine is used for steel or rebar cutting.

Semi-Automatic Drive-Belt Tensioning

The semi-automatic belt-tensioning system simplifies adjustment of the drive belt.

Maintaining the correct belt tension supports efficient power transfer and helps extend the service life of the belt and bearings. Adjustment and maintenance must be completed in accordance with the STIHL operating instructions.

Control Panel and Status Display

A control panel on the handle provides clear machine-status information from the operator’s normal working position.

The display can indicate operating status and warn the user if the machine is approaching an excessive operating temperature. This provides useful feedback during demanding or repeated cutting work.

What Can the STIHL TSA 350 Cut?

When fitted with the correct approved cutting wheel, typical applications include:

• Concrete and concrete products
• Reinforced concrete
• Paving slabs and paving blocks
• Kerbs and edging
• Bricks and concrete blocks
• Natural stone
• Clay bricks and clay pipes
• Asphalt
• Steel sections
• Reinforcing bar
• Stainless steel
• Ductile cast-iron pipe
• Approved plastic water pipes with the specified cutting wheel

Do not assume that one cutting wheel is suitable for every material. Diamond, composite resin and specialist cutting wheels are produced for different applications.

Using the STIHL TSA 350 Indoors

Because the TSA 350 does not have a petrol engine, it produces no combustion exhaust emissions at the point of use. This can make it suitable for appropriate indoor construction or refurbishment work where petrol machinery would be unsuitable.

Indoor use still requires a suitable risk assessment. Cutting concrete, brick, stone, steel or other construction materials can create hazardous dust, sparks, fragments and noise.

Always follow the machine and cutting-wheel instructions and use appropriate:

• Water suppression or dust extraction
• Ventilation
• Respiratory protective equipment
• Eye and face protection
• Hearing protection
• Hand protection
• Protective footwear
• Exclusion zones and site controls
