The STIHL TSA 300 is a professional 36V cordless cut-off saw for construction, hardscaping and pipework. Its powerful 2.5kW EC motor drives a 300mm / 12-inch cutting wheel and provides a maximum cutting depth of 110mm. Low vibration, an integrated water connection and a fast-stop brake help the operator make controlled, accurate cuts through demanding materials.
Tool only: this listing does not include a battery or charger. STIHL recommends the STIHL AP 500 S battery for maximum cutting performance. A compatible charger must also be purchased separately unless you already own one.

Professional cordless cutting performance
The STIHL TSA 300 is designed for professional users who need the cutting capacity of a 300mm disc cutter without the fuel mixing, exhaust fumes and regular engine maintenance associated with a petrol machine.
Its high-efficiency EC motor delivers consistent power throughout the usable battery charge. The narrow cutting kerf and low level of engine vibration help the TSA 300 achieve cutting performance comparable with the petrol STIHL TS 410 cut-off saw, while maintaining a compact and well-balanced design.
The machine weighs approximately 6.3kg without the battery or cutting wheel, making it considerably easier to handle than many conventional petrol cut-off saws.
What can the STIHL TSA 300 cut?
When fitted with the correct approved cutting wheel, the TSA 300 can be used to cut:
- Concrete and reinforced concrete
- Bricks and building blocks
- Paving slabs and kerbstones
- Natural stone
- Metal and reinforcing bar
- Pipes and hollow sections
- Asphalt, when fitted with a suitable asphalt cutting wheel
Always match the cutting wheel to the material. Masseys stocks a selection of cut-off saws, cutting wheels and accessories, including a STIHL 300mm concrete diamond cutting wheel and a STIHL 300mm concrete and asphalt cutting wheel.
300mm cutting wheel and 110mm cutting depth
The TSA 300 uses a 300mm / 12-inch cutting wheel and can cut to a maximum depth of 110mm. This gives it greater cutting capacity than the smaller STIHL TSA 230 cordless cut-off saw, making the TSA 300 better suited to deeper cuts in paving, concrete, brickwork and pipework.
A composite resin cutting wheel is supplied as standard. For longer or more intensive work in concrete, paving or asphalt, choose a suitable professional diamond cutting wheel.
Integrated water connection for wet cutting
The adjustable water connection supplies water directly to the cutting wheel. This helps cool the cutting area, bind airborne dust and improve visibility while cutting mineral materials.
Where there is no convenient mains-water connection, the STIHL WSA 40 cordless pressurised water container provides a portable automatic water supply for compatible STIHL cut-off machines.
Cutting concrete, brick, paving and stone can create hazardous respirable silica dust. The machine must be used with the appropriate water suppression, extraction, respiratory protection and other personal protective equipment required by the task, site assessment and operating instructions.
Fast-stop brake with energy recuperation
When the trigger is released, the fast-stop system automatically brakes the cutting wheel in less than four seconds. Energy recovered during braking is fed back into the battery, helping to improve the available working time.
Magnetic filtration for demanding site conditions
Ferromagnetic dust and particles can be drawn into a power tool during metal-cutting work. The TSA 300 uses magnets within the cooling-air path to capture these particles before they reach the motor.
The magnetic filter is removable for straightforward cleaning, helping to protect the internal components and maintain reliable performance.
Low-maintenance EC motor
The brushless EC motor operates with very little mechanical wear and does not require fuel mixing, spark-plug servicing or carburettor maintenance. STIHL Constant Power electronics maintain consistently strong performance rather than allowing the output to fall progressively as the battery discharges.
The machine produces no direct exhaust emissions during use and operates with lower noise and vibration than a petrol cut-off saw. This can make it a useful option for noise-sensitive, urban or partially enclosed working areas, provided all ventilation, dust-control and site-safety requirements are met.
Battery and charger requirements
The TSA 300 is part of the professional STIHL AP / ALLPRO Battery System.
STIHL recommends the AP 500 S battery for maximum performance. A fully charged AP 500 S provides approximately 20 minutes of quoted working time, although the actual result will depend on the material, cutting wheel, pressure applied and working method.
Smaller AP batteries may physically operate the machine but can reduce its available performance. For professional use, Masseys recommends budgeting for an AP 500 S battery and a rapid charger such as the AL 501. View the available STIHL battery chargers.
IPX4 protection and STIHL connected readiness
The TSA 300 is IPX4 rated for protection against splashing water from all directions, making it suitable for professional outdoor use in typical working conditions.
The housing is also prepared for an optional STIHL Smart Connector 2 A. When fitted, this can transmit operating information to the STIHL connected system to support tool and fleet management.

STIHL TSA 300 or TSA 230?
Choose the TSA 300 when you need a 300mm cutting wheel, cuts up to 110mm deep and higher professional cutting capacity. It is the stronger option for construction, hardscaping and pipework where the smaller machine’s cutting depth would be restrictive.
Choose the STIHL TSA 230 when lower weight, compact dimensions and shallower cutting tasks are the main priorities.
STIHL TSA 300 or TS 410 petrol cut-off saw?
The TSA 300 is well suited to users who value lower noise, reduced vibration, no direct exhaust emissions and lower routine motor maintenance. It is particularly attractive to contractors already using professional STIHL AP batteries.
The STIHL TS 410 petrol cut-off saw may remain the more practical choice for prolonged remote working where batteries cannot be charged or rotated easily. The right option depends on the cutting workload, site restrictions and access to charging facilities.
Why Masseys recommends the STIHL TSA 300
Masseys recommends the TSA 300 for professional users who want genuine 300mm cutting capacity without returning to a petrol-powered machine. It is compact, well balanced and powerful enough for demanding construction, landscaping and pipework applications, while the fast-stop brake, water connection and low-vibration design make it easier to control accurately.
We particularly recommend it to customers who already own STIHL AP System equipment, because the AP 500 S battery can also be used across a wide range of compatible professional STIHL tools.
Battery selection is important with this machine. Our team can help you choose the correct battery, charger, cutting wheel and water-supply equipment for the materials and workload you expect to encounter.

Frequently asked questions
Does the STIHL TSA 300 include a battery and charger?
No. The TSA 300 is supplied as a tool-only machine. A compatible STIHL AP battery and charger are required.
Which battery is recommended for the STIHL TSA 300?
STIHL recommends the AP 500 S for maximum cutting performance. Smaller compatible AP batteries may result in reduced output.
How long does the TSA 300 run with an AP 500 S battery?
STIHL quotes approximately 20 minutes of working time from a fully charged AP 500 S. Actual working time varies according to the material, cutting wheel, cutting pressure and operating method.
How deep can the STIHL TSA 300 cut?
It provides a maximum cutting depth of 110mm when used with a suitable 300mm cutting wheel.
Can the STIHL TSA 300 cut concrete?
Yes. It can cut concrete, reinforced concrete, brick, paving and natural stone when fitted with the appropriate approved cutting wheel. Water suppression and the correct protective equipment must be used where required.
Can the STIHL TSA 300 cut metal?
Yes. It can cut steel and reinforcing bar when fitted with a cutting wheel approved for the material.
Can the TSA 300 be used indoors?
Because it produces no direct petrol exhaust emissions during use, it can be suitable for some indoor or enclosed applications. This does not remove the risks from dust, sparks, noise or the material being cut. Appropriate ventilation, water suppression or extraction, PPE and a suitable risk assessment remain essential.
Does the TSA 300 have a water connection?
Yes. An adjustable water connection is built into the machine to supply water to the cutting wheel for cooling and dust suppression.
