Use 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 – up to 5x faster than standard hole saw arbors. Cut at an angle, and use two adapters (second adapter sold separately) on one pilot bit to enlarge existing holes.

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.
