Milwaukee Tool has launched a new M18 Fuel dual trigger braking angle grinder with One-Key, model 3676-20.
This is a 4-1/2″/6″ grinder with 15-position permanent side handle.
Powered by a brushless motor, the new grinder is said to deliver 13A corded performance and can make up to 135 cuts in 1/2″ rebar on a single battery charge.

Milwaukee says that their new M18 Fuel angle grinder was engineered for the most demanding applications, and purpose-built to deliver enhanced control and powerful performance.

The non-removable adjustable side handle has a secondary switch that is required for operation.
The grinder also features AutoStop tech for advanced braking and kickback control.
Why? Enhanced user safety. Some of you might be thinking “but I don’t want that!” From earlier conversations, I’m of the understanding that dual trigger activation tends to be a requirement or sought-after feature for larger construction companies. If this doesn’t sound appealing to you, Milwaukee has many other cordless grinders in their M18 Fuel lineup.
Milwaukee emphasizes that this and their other dual trigger angle grinder will not be replacing any models, and that they will continue to offer standard and enhanced safety options.

It also features One-Key for inventory management. Milwaukee says that One-Key helps professionals reduce downtime, prevent loss, and optimize fleet visibility across large jobsites or teams.

I’m not much of an angle grinder user myself, being mostly involved in telecom and audio/video, but the dual trigger safety feature seems more impractical than lifesaving. I likely haven’t used an angle grinder enough to appreciate the obvious safety feature this is.
Is this a way to prevent clothing from catching the wheel by forcing your sleeve outside of the blade radius?

I imagine it’s similar to dual trigger band saws – https://toolguyd.com/dual-trigger-cordless-band-saws/ – where commercial contractors are looking to avoid injuries.
Dual switches are about having to keep both hands on the tool.

Perhaps not as good as this one – but I got some positive feedback from a nephew who received my gift of a Metabo HPT 6-inch grinder back in 2023

I did not expect a lot – it was on sale for something like $186 on a BF promotion – but he does hardscaping work, and it apparently works for him
