💡 Why do brushless models outperform brushed versions in continuous jobs?
A modern brushless setup makes these tools incredibly handy for job sites because it removes friction from carbon contacts so you get longer runtimes and cooler operation during heavy cuts.
- Electronic commutation directs power straight to the armature for maximum efficiency under load
- Lower heat buildup protects internal electronics and extends the lifespan of your cutting wheels
- Lighter mechanical design reduces hand fatigue when working overhead or in tight corners
