Fein added an interesting feature to some of the angle grinders in their WS 14 line; they replaced the switch with four touch pads — two in the front and two in the rear.
You start the grinder by touching one of the font pads and one of the rear pads. The grinder will continue to operate as long as you touch one of the four pads and will slow to a stop when you release it. Just so you don’t accidentally start it, you can lock the grinder off.
The compact and ergonomic grinder can be configured for left- or right-handed use. The grinder also features their quick change system for changing discs without tools, shock proof encapsulated electronics, soft start, and an integrated guard.
Pricing starts at $225 for the Fein’s “tip start” angle grinder.
