The Spyder Dado Blade Set is the ideal choice for ultra clean cuts in wood materials. Over-sized and resharpenable NiCo teeth are sharpened in an alternating tooth grind with a flat grind (ATG+F) to provide clean cuts in both soft and hard woods. Tracking straight with reduced friction, heat and noise, circular saw blades are the professional choice for cutting groves in all new wood materials from 1/4-in to 7/8-in in width. Up to 6x the life of standard carbide blades. Set includes: (2) 12-tooth cutting blades, (3) 2-tooth chipper blades, (3) spacers, (8) alignment shims.

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.
