Bosch UniversalChain 18: The Powerhouse for General Cutting
The Bosch UniversalChain 18 is a well-regarded cordless chainsaw that fits into the extensive Bosch 18V PowerForAll system. It is designed for users who need a reliable saw for cutting firewood, trimming thicker branches, and performing general garden maintenance. The 25cm bar provides a good balance between reach and control, making it suitable for most residential cutting tasks.
Owner reviews consistently highlight its robust build quality and consistent cutting performance. The automatic chain lubrication system is praised for being effective and low-maintenance. However, some users note that the battery life can be limited during heavy use, and the saw is slightly heavier than some competitors, which might cause fatigue during extended sessions.

Powerful and reliable for general cutting and firewood.
Bosch UniversalChain 18
Best for General CuttingPros
- Strong cutting power for thicker branches
- Part of the versatile PowerForAll battery system
- Automatic chain lubrication is effective
Cons
- Heavier than some competitors
- Battery life can be limited under heavy load
The Bosch UniversalChain 18 is a solid performer that excels at cutting through medium to thick branches and small logs. Its 25cm bar and 4.5 m/s chain speed provide efficient cutting, and the automatic oiler keeps the chain running smoothly without constant attention. The saw feels well-built and durable, with a comfortable grip that reduces vibration.
However, its weight (2.8 kg with battery) is a notable drawback for some users, especially during prolonged use. The battery life is also a common point of feedback, with some owners finding they need a second battery for larger jobs. Despite these points, it remains a top choice for those who need a reliable, powerful saw for general garden work.
Flymo Contour Cordless Chainsaw: The Lightweight Pruner for Small Gardens
The Flymo Contour Cordless Chainsaw is designed with the home gardener in mind, focusing on lightness and ease of use for pruning and trimming tasks. With a 20cm bar, it is best suited for cutting smaller branches, shaping hedges, and maintaining ornamental trees. Its low weight makes it easy to handle for extended periods, even for users with less upper body strength.
Aggregated owner reviews often mention its excellent manoeuvrability and how easy it is to start and operate. The automatic oiling system is also appreciated for its simplicity. However, some users find it underpowered for larger cutting jobs, and the chain tensioning mechanism can be fiddly to adjust without tools. The battery life is generally adequate for light tasks but may not last for a full day of heavy pruning.
Flymo Contour Cordless Chainsaw
Best for Light PruningPros
- Very lightweight and easy to handle
- Great for quick pruning and trimming tasks
- Simple to start and operate
Cons
- Underpowered for thicker branches
- Chain tensioning can be fiddly
The Flymo Contour is a joy to use for light garden maintenance. Its low weight (2.2 kg) makes it easy to manoeuvre into tight spots and hold for extended periods without fatigue. The 20cm bar is perfect for cutting branches up to about 8cm in diameter, and the automatic oiler ensures the chain stays lubricated during use. It is a great tool for keeping hedges and small trees tidy.
On the downside, its power is limited, and it will struggle with larger branches or logs. The chain tensioning system requires a tool and can be a bit tricky to get right. Battery life is decent for light work, but you may need to recharge or swap batteries for a full day of pruning. It is best seen as a convenient, lightweight option for the casual gardener.
What to Check Before Buying a Cordless Chainsaw
Before choosing between Bosch and Flymo, consider the typical size of branches you will cut. For branches over 10cm in diameter, the Bosch with its 25cm bar is the better choice. For lighter pruning, the Flymo is sufficient. Also, check the battery system: if you already own Bosch 18V tools, the UniversalChain 18 is a logical addition. If you prefer a saw that comes with its own battery and charger, the Flymo KIT is convenient. Finally, consider the weight and ergonomics, especially if you plan to use the saw for extended periods or at height.
Mistakes to Avoid When Buying a Cordless Chainsaw
A common mistake is buying a saw with too short a bar for the tasks you need to do. Always measure the thickest branch you expect to cut and choose a bar length at least 5cm longer. Another mistake is ignoring the battery system; buying a tool that uses a proprietary battery can lock you into an expensive ecosystem. Finally, do not overlook the importance of an automatic oiler. Manual oiling is messy and easy to forget, leading to premature chain wear.
Battery and Ecosystem: Which Brand Offers More Value?
Bosch has a significant advantage with its 18V PowerForAll system, which is shared with dozens of other tools from Bosch Home & Garden and other brands. This means the battery you buy for the chainsaw can also power drills, grass trimmers, and leaf blowers. Flymo's 20V system is more limited, primarily used for its own range of garden tools. For users who plan to expand their cordless tool collection, Bosch offers better long-term value and flexibility.
Build Quality and Warranty: Which Saw Lasts Longer?
Bosch is known for its robust build quality and reliable engineering. The UniversalChain 18 feels solid and well-constructed, with a durable plastic housing and metal components where needed. Flymo, while a reputable brand, uses more lightweight plastics to keep the weight down, which can feel less durable over time. Both brands offer a standard 2-year warranty, but Bosch's warranty is often extendable through registration, providing added peace of mind.
Performance in Different Cutting Scenarios
For cutting firewood or thick branches, the Bosch UniversalChain 18 is the clear winner. Its longer bar and faster chain speed allow it to cut through logs up to 20cm in diameter with relative ease. The Flymo Contour is better suited for precision pruning and trimming, where its lightweight design and smaller bar make it easy to navigate around shrubs and trees. For general garden maintenance, the Bosch is more versatile, but the Flymo is more specialised for light work.
