Are you looking for the best cordless chainsaw for making high precision cuts? Electric chainsaws don`t have the same strong punch you receive from a gas-powered chainsaw, although they are cleaner and more maneuverable. The cordless chainsaws are the best for cutting pesky branches, felling logs and pruning at home, on the farm, or camp. You, however, need to invest in the combination of a powerful motor and a heavy-duty high-gauge steel chain.

Top power tool manufacturers have the best motor technology that can deliver that strong punch, and who better to buy from than Dewalt? You won’t have to search for long before someone recommends a Dewalt cordless chainsaw to you. Professional woodworkers and homeowners praise Dewalt chainsaws as the best for high-quality cuts.

DEWALT DCCS670X1 FLEXVOLT 60V MAX Lithium-Ion Brushless 16" Cordless Chainsaw Kit (3.0AH)

Overview

A 60V motor from Dewalt is a power you can trust to handle more than just regular cutting. This chainsaw was a major relief for Dewalt fans as it runs on both 20V and 60V Dewalt batteries. Many fans, however, complain because the runtime on 20V batteries is too short for all-day projects. It is, however, Dewalt`s giant torque solution for homeowners and woodworkers that need to fell medium-sized trees, chop logs. It is still light and compact enough to lift overhead for trimming and pruning.

Power

Despite its 20V compatibility, this chainsaw is fitted with a 60V brushless motor. It has the high speed and torque needed to cut past tough and fibrous trees, which is why this chainsaw can be used to fell and chop huge logs. Its high-speed motor delivers speed over 6500RPM, which is more powerful than a 40cc gas-powered chainsaw.

The four-pole motor delivers over 200 Watt-hours with a 60V 6Ah battery which is enough for all-day projects. It is also brushless, so there is no maintenance needed on the motor. This chainsaw is still compatible with 20V batteries from Dewalt, which allows you to share with your cordless drill or impact wrench if you are not doing continuous cutting.

Performance

The main advantage of this chainsaw is high-speed operation that goes through the bark with little effort compared to 20V and 40V chainsaws. It cuts through a 10-Inch thick dry oak in less than one minute, meaning you can cut over 100ft in one hour. Its greatest drawback is the 3.5oz oil tank that requires regular refills.

Dewalt, however, included a simple quarter turn oil cap that allows you to open and refill in seconds. It gives you less runtime on 20V batteries, so you should only resort to those if you don`t have 60V models.

High voltage on a cordless chainsaw means more power, which is why Flexvolt is the best chainsaw for the most tasking all-day projects. 609M1 is also a powerful chainsaw, although its40V chainsaw has lower speeds compared to over 6600RPM delivered by Flexvolt. 620 is a small chainsaw only built for the lightest and non-continuous cutting projects.

Batteries

If you are planning to use the chainsaw far from a power supply, it is advisable to carry a spare battery. All these chainsaws have battery efficient brushless motors that will give you up to 1hr of power on a 5Ah or a 6Ah battery.
