Walter Surface Technologies 15Q456 Flap Disc 60 Grit

Product Description

The WALTER SURFACE TECHNOLOGIES 15Q456 is a Type 27 zirconia alumina flap disc engineered for aggressive material removal on stainless steel. Built on a wood fiber backing, this 4.5-inch disc runs at a maximum of 13,300 RPM and delivers consistent cut rates with a medium 60-grit abrasive. The trimmable design allows the operator to extend disc life by trimming worn flaps, making it practical for high-output fabrication work. Metalworkers, pipe fitters, and weld-prep technicians reach for this disc when blending welds or smoothing stainless surfaces where contamination control matters.

The 15Q456 belongs to the Enduro-Flex Stainless series, which is formulated specifically for use on stainless steel and other ferrous materials where iron contamination must be avoided. The 7/8-inch arbor hole fits standard 4.5-inch angle grinders common in shop and field environments. Its Type 27 depressed-center profile suits flat surface grinding and weld blending at low angle approaches, common in structural steel, pressure vessel, and food-grade equipment fabrication.

Key Features

• Type 27 depressed-center profile for flat surface grinding and weld blending
• 60-grit medium-grade zirconia alumina abrasive for aggressive stock removal
• Wood fiber backing for durability and flexible flap movement under load
• Trimmable flaps extend usable disc life in production environments
• Rated to 13,300 RPM for use on standard 4.5-inch angle grinders
• Formulated for stainless steel applications where contamination control is required

Compatibility

Designed for use with 4.5-inch angle grinders equipped with a 7/8-inch arbor. Part of the Enduro-Flex Stainless series, intended for grinding and finishing stainless steel surfaces.

Installation Notes

Installation and use should be performed by qualified metalworkers or fabricators familiar with angle grinder safety. Always confirm the grinder's rated RPM meets or exceeds the disc's 13,300 RPM maximum before mounting. Power down and disconnect the grinder before mounting or removing the disc. Wear appropriate PPE including face shield, gloves, and hearing protection during operation, and never exceed the disc's maximum RPM rating.
