87920 Speedbor Spade Drill Bit, 1-1/4 X 4 In., Hex Shank

The Irwin Speedbor 87920 Spade Drill Bit is a wood boring tool engineered for precision drilling in tight spaces and confined areas. Its compact 4-inch length allows you to drill between studs, rafters, and inside cabinet interiors where standard drill bits cannot reach, making it ideal for renovation projects, wiring installations, and shelving work. The 1-1/4-inch cutting diameter creates generous holes for wiring, plumbing, and hardware while maintaining structural integrity.

This spade bit solves common drilling challenges by delivering clean, straight holes without wobble or walk-out. The sharp cutting edges and blue groove point reduce setup time and material waste, allowing faster job completion with professional-grade results on every application.

Features and Benefits

• Blue Groove Point and Cutting Edge: Designed for faster chip removal during the drilling process.
• Double Cutting Spurs: Scribe the outside of the hole to minimize breakout and deliver straight, precise passages on wood surfaces.
• Hex Shank Design: Grooved hex shank prevents slipping in drill chucks or bit extensions and fits all standard quick-change chucks for secure, reliable grip.
• Flat Flute Construction: Delivers consistent wood boring performance.
• Compact 4-Inch Length: Enables access to hard-to-reach drilling locations without awkward angles or extra setup.
