Irwin 88810 FLAT BIT 5/8″ X 6″

IRWIN 88810 SPEEDBOR 5/8″ x 6″ Spade Bit is built for fast, efficient wood drilling in high-demand jobsite environments. Designed for use with power drills and impact drivers, this spade bit features IRWIN’s patented Blue-Groove™ point and chamfered cutting edges that reduce splintering and improve chip removal—drilling up to 2X faster and lasting 2X longer than traditional flat spade bits. The 5/8″ diameter makes it ideal for general rough-in tasks, such as drilling through studs, joists, and beams for wiring, plumbing, or conduit installations. With a heavy-duty 10% larger shank and grooved hex base, it minimizes slippage in the chuck, providing stability and precision for both DIYers and professional tradespeople.

Built for speed and control, the 6″ length gives you access to deeper bore holes while maintaining a stable drilling path. Whether you’re working with softwoods, hardwoods, or engineered lumber, this spade bit holds up to repetitive use and high-torque applications. It’s compatible with all standard 1/4″ quick-change chucks, making it a time-saving option for electricians, framers, HVAC installers, and woodworkers needing consistent results on every pass.
