Walter Super-5 PS 5-Inch Angle Grinder with Mechanical Brake

The Safest 5-Inch Grinder for Professional Welders

When you are in the middle of a fabrication job, the last thing you want to worry about is your grinder kicking back or coasting when you set it down. The Walter 6153 Super-5 PS™ is built with the welder's reality in mind. This isn't just another 5-inch grinder; it is a safety-focused powerhouse designed to keep you working efficiently and, most importantly, safely. The standout feature here is the mechanical brake. We've all waited for a grinder wheel to stop spinning before we can put it on the bench—or worse, had it catch a cable. With the Super-5 PS, the wheel stops dead in under two seconds the moment you let go of the trigger.

The paddle switch design is a favorite among fabricators for its ease of use and safety. It fits naturally in your hand, allowing for a secure grip even when wearing heavy welding gloves. Because it's a non-locking switch, the tool shuts off instantly if it slips from your hand, preventing potential injuries. But Walter didn't stop there. They included a Safety Clutch that saves your wrists (and the gearbox) if your cutting wheel gets pinched in a pipe or plate. Instead of the grinder jerking violently, the clutch slips, letting you regain control immediately.

Durability is key in a weld shop, and the Super-5 PS delivers. It features Powerguard™ technology, which acts like a built-in brain for the motor. If you push the tool too hard and it starts to overheat, an LED light warns you, and the tool will cut power to save the motor from burning out. Add in the Soft Start feature that stops the tool from jumping out of your hand when you fire it up, and you have a grinder that is smooth, powerful, and incredibly safe. Whether you are beveling plate, grinding down welds, or cutting stock, this Walter grinder is the reliable partner you need in your booth.
