15R454 - Walter Enduro-Flex 4.5 Inch Grit 40 Flap Disc with 5/8-11 Hub

High-Performance Zirconium Blending Disc

The Walter 15R454 Enduro-Flex™ Blending Disc is engineered to meet the rigorous demands of the metal fabricating and finishing industry. This 4-1/2 inch disc, featuring a coarse Grit 40, utilizes a new generation of ultra-sharp refined zirconium grain. This advanced abrasive formulation ensures that the disc stays sharper for significantly longer periods while removing material at an accelerated rate compared to conventional flap discs. Designed for efficiency, the Enduro-Flex series provides a one-step finishing solution, allowing operators to grind and blend welds without changing tools, thereby reducing downtime and operational costs.

A standout feature of this product is the patented Eco-Trim™ trimmable backing. Unlike standard discs that must be discarded once the flap overhang wears down, the Enduro-Flex backing can be safely trimmed to expose fresh abrasive material. This innovation extends the useful life of the disc by up to three times, offering substantial cost savings over the lifespan of the consumable. The backing is made from a composite material that is easy to trim and environmentally friendly.

In addition to its longevity, the 15R454 is designed for operator comfort and finish quality. It incorporates a special top coat that continuously cools and lubricates the contact zone. This results in smooth, vibration-free grinding and sanding, preventing heat buildup that can warp or discolor the workpiece. The disc comes equipped with an integral 5/8"-11 threaded hub, ensuring compatibility with all standard angle grinders and facilitating quick, tool-free changes. Manufactured in Germany, this disc represents a premium solution for heavy-duty stock removal and finishing on steel and stainless steel surfaces.
