Walter Surface Technologies 15I453 Type 27 Flap Disc 150 Grit

Product Description

The WALTER SURFACE TECHNOLOGIES 15I453 is a Type 27 flap disc engineered for use on angle grinders in metalworking and fabrication environments. Part of the Enduro-Flex 2-in-1 series, it combines coated and non-woven abrasive layers into a single disc, allowing technicians to grind and finish in one pass. The disc measures 4-1/2 inches in diameter with a 5/8-11 arbor hole and is rated to a maximum of 13,300 RPM. The 150 grit, medium-grade aluminum oxide construction is suited for controlled material removal and surface conditioning on a range of metals.

This flap disc is designed for use on aluminum, non-ferrous metals, stainless steel, and carbon steel. The coated and non-woven combo construction makes it well suited for applications that require both aggressive cutting action and a consistent surface finish in the same operation. Typical install scenarios include weld blending, deburring, and surface prep work in fabrication shops, mechanical contractors, and industrial maintenance settings. The plastic backing provides rigidity while keeping weight low at 0.1 pounds per disc.
