15R504 - Walter Enduro-Flex 5-Inch Flap Disc 40 Grit Type 27

Premium Zirconium Flap Disc for Heavy Stock Removal

The Walter Enduro-Flex™ 15R504 is a high-performance 5-inch flap disc designed to meet the rigorous demands of industrial metal fabrication. Engineered with a coarse 40-grit zirconium grain, this Type 27 disc delivers exceptional material removal rates on both steel and stainless steel applications. The refined zirconium abrasive self-sharpens during use, ensuring a consistent cut rate and surface finish throughout the product's lifespan, making it ideal for heavy weld removal, edge chamfering, and surface blending.

A standout feature of the Enduro-Flex series is the patented Eco-Trim™ backing. Unlike traditional fiberglass backings that limit the usable life of the abrasive, the Eco-Trim backing is manufactured from a specialized polymer that can be easily trimmed away. As the flap overhang wears down, the operator can reduce the backing diameter to expose fresh abrasive material that would otherwise be discarded. This innovative design extends the disc's life by up to three times compared to standard competitors, offering substantial cost savings and improved efficiency in high-volume production environments.

Operational comfort is enhanced through a vibration-absorbing backing structure that promotes quiet, smooth grinding. The Type 27 profile provides the optimal angle for flat surface finishing and blending. With a standard 7/8-inch arbor, the 15R504 is compatible with most industrial angle grinders. This disc represents a one-step finishing solution that combines aggression with longevity, reducing the frequency of disc changes and increasing overall throughput.
