Spyder 1" Reduced Shank S&D Drill Bit, Tri-Flat Machined Shank for No Slipping, 135° Self-Centering Split Point, Advanced Alloy for Metal and Wood Drilling (19160)

Spyder Mach-Blue Armor Plated S&D Bits deliver unmatched power, precision, and durability for large-diameter drilling in metal, wood, and plastic. Built from advanced M-series high speed steel and treated with Spyder’s exclusive Mach-Blue armor plating, these bits stay sharper longer, resist heat buildup, and cut cleaner through the toughest materials. The tri-flat shank design prevents bit slippage and ensures maximum torque transfer in standard drill chucks, while precision-ground flutes provide fast chip removal and smooth, accurate drilling. Engineered for demanding professionals, Spyder S&D bits deliver superior strength, control, and long-lasting performance—job after job.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.
