Cons

DeWalt DCCS690 18" Chainsaw
Best Large BarPros
- Largest bar in this class
- Good power for its size
- Tool-free adjustments
Cons
- Heavy and can be unwieldy
- Battery drains fast with 18" bar
The DeWalt DCCS690 is the only 18-inch cordless chainsaw in this roundup, making it the best choice for professionals who need to cut larger diameter timber. It uses the same FlexVolt 60V platform as the DCCS670 but with a longer bar and more aggressive chain. Owner reviews note it can handle 20-inch logs with ease.
The saw features a brushless motor and an efficient oiling system. The main trade-off is weight and battery consumption. With the 18-inch bar, the saw requires a high-capacity battery to get through a full day of work. It is best suited for users who need the extra reach and cutting capacity.
What to Check Before Buying a Professional Cordless Chainsaw
Battery ecosystem is the most important factor for professionals. If you already own a platform like Milwaukee M18 or DeWalt FlexVolt, staying within that system saves money on batteries and chargers. For new buyers, consider the availability of high-capacity batteries (12.0Ah or larger) as they are essential for sustained cutting.
Bar length should match your typical work. A 16-inch bar is versatile for most tasks, while a 12-inch bar is best for limbing and a 18-inch bar for larger logs. Chain speed and torque are also critical. Look for brushless motors and automatic oilers for low maintenance.
Mistakes to Avoid
Do not buy a saw based solely on bar length. A longer bar requires more power and battery capacity, which can lead to poor performance if the motor is underpowered. Always check the motor specs and battery amp-hour ratings.
Avoid using standard 18V batteries on high-drain saws. Many professionals report that standard 5.0Ah batteries cause the saw to stall under load. Invest in high-output or high-capacity batteries for reliable performance.
