STIHL TS 420 Petrol Cut-Off Machine (42380112810)

STIHL TS 420 Cut-Off Machine: All-Purpose, User-Friendly Petrol Disc Cutter

When a project demands strength, control, and dependable performance, the STIHL TS 420 Petrol Cut-Off Machine makes a trusted companion for both professional and serious DIY users. Compact yet powerful, this STIHL concrete cutter saw is ideal for road construction, landscaping, and heavy-duty building tasks, combining A1 operator comfort with impressive durability. Whether used as a handheld cut off saw or with the STIHL FW 20 cart, the STIHL TS420 delivers consistently great results. 

Compact Strength and High Cutting Capacity

The TS STIHL 420 cutoff saw is a small disc cutter with a robust 2-MIX engine, delivering 3.2kW (4.3 horsepower) from its 66.7 cm³ displacement. This highly efficient engine reduces emissions and fuel use, lowering overall running costs without compromising on performance. With a standard 350mm (14-inch) cutter disc*, the tool achieves a maximum cutting depth of 125mm, being ideal for working on concrete, stone, or asphalt. Its dry weight of 9.8 kg and balanced frame ensure you can operate the TS420 confidently throughout your cutting work. 

(*Please note that the STIHL saw TS 420 is supplied with a 350mm abrasive wheel, although STIHL recommends using a D-SB90 diamond cutting wheel for extended or intensive jobs.) 

Designed for Easy Starting

Getting the STIHL TS 420 saw running is easy thanks to several intelligent design features. The manual fuel pump primes the system quickly, reducing the number of strokes required to start. Alongside this, the decompression valve lowers the force needed on the starter cord, protecting the mechanism and making the start-up process smoother. STIHL’s ElastoStart technology adds yet another layer of convenience, cushioning the strain of pulling the cord and ensuring consistent starts even after extended breaks in use. 

Comfort and Control in Every Cut

Powerful tools can often cause strain to the user, but the STIHL saw TS420 has been designed with operator comfort in mind. STIHL’s anti-vibration system reduces transmission of vibrations to the handle (recorded at just 3.9 m/s²), minimising fatigue during tough cutting sessions. The STIHL 420’s ergonomically shaped handle provides excellent grip and enables precise guidance along marked lines, ensuring straight, controlled cuts every time. With quiet running and steady balance, these STIHL disc cutters allow you to work with confidence and accuracy at all times. 

Clean Operation and Reduced Maintenance

Another advantage of the STIHL disc cutter TS420 is its intelligent approach to air filtration. A pre-separation system uses a cyclone motion to remove up to 80% of dust before it reaches the filter, significantly extending the filter’s lifespan. This works hand in hand with a compensator in the carburettor, which maintains power and efficiency even as the filter becomes loaded. The result is that the STIHL TS 420 runs cleanly with less frequent servicing. For additional support, we sell STIHL Service Kit 35 and STIHL HP Super 2-Stroke Engine Oil as optional extras to keep your disc cutter performing at its best. 

Further Practical Features

The STIHL TS420 disc cutter comes with other practical features. Its water connection feeds directly to the cutter disc, cooling the blade and binding dust for safer, cleaner operation. Semi-automatic drive belt tensioning helps you keep the belt at the correct setting, extending its lifespan and reducing wear on the bearings. Meanwhile, a bayonet filler cap allows fuel to be topped up quickly without the need for extra tools, making the machine easier to use in the field.
