Husqvarna Construction 542761409 Segmented Diamond Blade

Product Description

The HUSQVARNA CONSTRUCTION 542761409 is a TSD-S segmented diamond blade designed for cutting ceramic tile, stone, fiberglass, and cement siding. The blade measures 4.5 inches in outer diameter with a segment thickness of 0.080 inches and accepts a 7/8-inch, 20 mm, or 5/8-inch bushing arbor, making it compatible with a wide range of angle grinders, circular saws, and tile saws. It supports both wet and dry cutting applications. This blade is intended for installation and tile-setting professionals who need consistent performance across multiple hard materials in the field or on the shop floor.

This blade is suited for residential and light commercial tile and masonry work. Typical applications include cutting ceramic floor and wall tile, natural stone slabs, fiber-cement siding panels, and fiberglass materials. The segmented rim design promotes airflow and debris clearance during dry cuts while still performing reliably in wet-cutting setups. It is sized for use on standard 4.5-inch angle grinders and compatible tile saw arbors. Each package contains 5 blades.
