It looks like DeWalt recently issued upgraded versions of their 4-1/2″ (pictured) and 6″ angle grinders recenty, featuring a new grip and a “dust ejection system” designed to keep debris out of the motor — a feature Metabo’s been touting for years.
The “vibration-reducing” handle looks comfy. We’d imagine DeWalt added it in order to meet ever-changing European safety specs. (Our friends across the ocean seem a lot more concerned about the prolonged affects of vibration on tool users than OSHA, at least for now.) One other feature we don’t remember seeing on the old ones (though we might have missed it): sensors that automatically shut the tool off when the motor brushes need replacing to prevent damage.
I’ll admit to owning an older low-end DeWalt 4-1/2″ grinder which I’ve been pleased with. I paid around $70 for it at the time, and it’s worked great since then. Street pricing on the new replacement starts around $130, though, which puts it in a different league than my cheapie.
