48M807 - Walter Safety Brake Disc for Angle Grinders

Technical Overview of the Walter 48M807 Brake Disc

The Walter 48M807 Brake Disc is a specialized safety accessory engineered to enhance the operational security of handheld angle grinders. Designed specifically for use with 4-1/2 inch and 5-inch angle grinders equipped with a standard 5/8"-11 threaded arbor, this component addresses one of the most common hazards in metalworking: the coast-down time of abrasive wheels.

In standard grinder operation, the momentum of a grinding or cutting wheel can cause it to spin for several seconds—or even minutes—after the trigger is released. This residual rotation poses a significant risk of injury to the operator or damage to the workpiece if the tool is set down prematurely. The Walter Brake Disc functions as a mechanical braking interface that drastically reduces this deceleration period, bringing the wheel to a complete halt rapidly after power is cut.

Constructed from durable materials capable of withstanding the high torque and heat generated during industrial grinding applications, the 48M807 is an essential addition to safety-conscious fabrication shops. It integrates seamlessly with the grinder's spindle assembly, ensuring that the braking action is consistent and reliable without interfering with the tool's balance or performance during use. By minimizing the time an operator must wait before setting the tool down, this accessory not only prevents accidents but also incrementally improves workflow efficiency.
