Buying Guide
- Power vs. weight: Shorter cuts require lighter tools, while heavy framing tasks benefit from higher motor power (MWO) and RPM figures.
- Bevel capacity and cut depth: Ensure the saw reaches the depth needed for your typical projects, and check if 45° and 50° settings cover your most-used angles.
- Brushless motors: Generally deliver longer run time per charge and extended tool life; consider models labeled XR or similar for higher performance.
- Dust management: A built-in chute or compatible dust extraction reduces debris and improves accuracy over time.
- Battery ecosystem: If you own other 20V tools, verify compatibility to maximize runtime and simplify charging needs.
- Ergonomics and grip: An optimized rubber overmold and balance reduce fatigue during extended use.
- Compatibility and accessories: Look for auxiliary handles, depth adjustments, and included kits (batteries, chargers) to match your shop setup.
- Durability: Magnesium shoes and sturdy housings contribute to lifespan in demanding environments.
