Spyder TCT Hole Saw 4.5 in.

The Spyder 4.5-inch Tungsten Carbide-Tipped (TCT) hole saw is built for pros who demand speed, durability and versatility. Its precision-ground carbide teeth stay sharper up to 10× longer than bi-metal hole saws, while high-speed cutting geometry delivers up to 5× faster material removal. Whether you’re enlarging an existing opening or drilling a fresh hole, this TCT bit tackles wood, composites, masonry products and more without the need to swap tools.

Designed for use with any standard 5/8″-18 arbor (sold separately), the Spyder TCT hole saw ejects cores easily, cuts at angles and powers through demanding applications—all while maintaining a clean, burr-free edge. Always pair with a drill motor equipped with a side-handle and avoid hammer-drill mode for best results.
