Spyder's Tungsten Carbide-Tipped (TCT) hole saws cut more materials up to 5x faster and make up to 10x more cuts — lasting longer than conventional bi-metal hole saws. TCT hole saws drill through wood, MDF, fiber cement board, porous concrete block, ceramic wall tile, plastic/PVC and more. Use with Spyder's Rapid Core Eject arbor system to remove cores without prying (drill hole, press button, pull back the hole saw, and eject the core), cut at an angle, and enlarge existing holes using two adapters on one pilot bit. All TCT, Tarantula, and Bi-Metal hole saws fit on Spyder Rapid Core Eject arbors and pilot bits (sold separately), and on universal hole saw arbors. Spyder's TCT hole saw is the pro's choice for innovation, high performance, speed, and versatility — drill more holes in more materials in less time. Not for use in hammer mode, or for drilling metal, wood with nails, harder, abrasive materials, or block/brick/tile applications with a Mohs hardness of 6 or greater. Always use a drill with a support handle.

As a professional plumber, electrician or contractor, you put your tools through hell every day. You need tools that will last.

Spyder tools are made tough. They're built to perform under the harshest conditions, time and time again. Starting in 2007 with the Spyder Scraper, and continuing with award-winning 3×3, jig saws, hole saws and more, Spyder has quickly developed a reputation for making quality tools that pros trust.

While most other tool companies have long since stopped innovating, we've found ways to make blade attachments that work harder, last longer and finish the job faster.

If you make your living with power tools, you owe it to yourself to give Spyder tools a try.
