Tungsten carbide-tipped holesaws are purpose-built for abrasive, hard, or specialty materials — including tile, fiberglass, brick, ceramic and some hardened steels. Tungsten carbide tips are brazed to a steel body to combine the toughness of a steel core with the cutting hardness needed to cut brittle or reinforced substrates without chipping. These cutters are the go-to for installers, tilers, and tradespeople who routinely work with masonry, composites, and reinforced plastics. Use at lower speeds with controlled feed and, where appropriate, light water cooling for ceramic or porcelain. Compatible with standard arbors, they’re essential when you need durability and repeatable performance on hard materials that would rapidly blunt conventional teeth.
