pyrcruax EF-20CS16 16-Inch 40V Brushless Cordless Chainsaw
Product description
For storm cleanup, firewood preparation, and cutting fallen limbs, the pyrcruax EF-20CS16 pairs a 16-inch bar with a brushless motor and a 40V battery setup. It is designed for homeowners who want a cordless saw for property work, with automatic chain lubrication and tool-free tension adjustment to make routine operation more straightforward.
The saw runs on two DeWALT 20V MAX batteries at once to create its 40V system. Batteries and charger are sold separately, so it’s a practical fit for shoppers who already have compatible packs or plan to source them separately.
Why it makes sense
A 16-inch bar and stated maximum cut diameter of 16 inches give this chainsaw a useful range for storm-fallen trees, firewood, and general property cleanup. Its brushless motor delivers up to 2 hp, while the chain speed is listed at 52 ft/s. Rather than choosing a gas-powered saw, buyers can use a cordless setup powered by two compatible 20V MAX battery packs, without handling gas for the saw.
The chain is lubricated automatically as you work, and the tool-free tensioning system lets you adjust chain tightness without reaching for a separate tool. Buyers describe the saw as powerful and quick, and some appreciate its easy tension adjustment. Feedback on battery life is mixed, so the battery packs you choose are an important part of the setup.
Key features
The EF-20CS16 uses a 40V system formed by two DeWALT 20V MAX batteries installed together. The manufacturer recommends packs rated at 4.0Ah or higher for cutting power and runtime, 2.0Ah packs are not recommended. This bare-tool configuration is intended for buyers who want to use compatible batteries they already own or select their own packs and charger.
Its 16-inch guide bar works with a 3/8-inch low-profile chain with a .043-inch gauge. The included components are the chainsaw, guide bar and bar cover, two 16-inch chains, and a user manual with a quick-start guide. Safety features include an instant-stop chain brake, a trigger safety lock, and low-kickback chain geometry. These controls support more deliberate handling during cutting tasks, follow the manual’s instructions for setup and operation.
Cleaning & care
The automatic oiler feeds lubricant to the chain during operation, and the reservoir is described as providing up to 20 minutes of continuous cutting per fill. Check the oil level before each cutting session and refill as needed. Keeping the chain properly tensioned also supports clean, controlled cutting, the tool-free adjustment lets you make that change without additional tools.
For a typical yard-cleanup session, install two compatible batteries, check the chain oil and tension, then use the saw to process fallen branches or prepare logs for firewood. After use, follow the included manual for care and storage of the saw, bar, and chain.
Questions before you buy

Buying verdict
The pyrcruax EF-20CS16 is suited to property owners handling storm debris, firewood, and other jobs within its 16-inch cutting range. Its brushless motor, automatic oiling, tool-free tension adjustment, and two-battery 40V platform bring practical features together in a cordless chainsaw. It makes particular sense when you want a 16-inch saw and can power it with compatible DeWALT 20V MAX packs.
