The Mach-Blue Armor Plating combined with the advanced M-series alloy tool steel construction and proprietary heat treatment make these bits truly revolutionary — they retain sharper cutting edges for longer, have reduced heat build-up and cutting friction, and increased durability, rigidity, and breakage resistance. These incredibly durable bits are the pro’s choice for precision drilling, extended bit life, and value. Ideal for electrical work and other applications in sheet metals, including enlarging 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.
