Description

Reach Further and Drill Faster with Diablo’s Extended 16-Inch Self-Feeding SPEEDemon™ Spade Bits

The Diablo DSP3050 SPEEDemon™ Extended Length Spade Bit is the ultimate solution for deep-reach wood boring in professional construction, electrical, and plumbing rough-ins. Featuring a massive 16-inch overall length, this bit is specifically engineered to drill through multiple wall studs, thick floor joists, or hard-to-reach rim joists with ease. The revolutionary SPEED-TIP™ self-feeding design acts as a lead screw, effortlessly pulling the bit through the wood with minimal physical pressure, which significantly reduces user fatigue and preserves the battery life of your cordless tools.

Forged for maximum durability on the modern jobsite, this bit is Impact Strong™, making it fully compatible with high-torque impact drivers and standard drill drivers alike. The optimized Curved Paddle design facilitates rapid chip evacuation, clearing wood debris quickly to prevent heat buildup and allowing for more holes per battery charge. Equipped with an angled spur cutting edge, the DSP3050 scores the wood surface before boring to ensure clean, smooth entry points with minimal blowout, making it a high-efficiency essential for any contractor needing extended reach without sacrificing speed.

Key Features

  • SPEED-TIP™ Self-Feed Design: Automatically pulls the bit into the wood for faster, more controlled hole-making with minimal effort.
  • Extended 16-Inch Length: Specifically designed for drilling through deep wall cavities and stacked framing components where standard bits cannot reach.
  • Optimized Curved Paddle: Rapidly removes wood chips to prevent clogging and increase the number of holes drilled per battery charge.
  • Impact Strong™ Hex Shank: Provides a secure fit and increased stability in impact drivers, eliminating bit slippage in the chuck.
  • Angled Spur Cutting Edge: Precisely scores the wood surface for professional-grade clean holes and reduced surface splintering.

Pro-Tip: When using extra-long 16-inch bits for plumbing or electrical rough-ins, maintain a firm, two-handed grip on your tool. Because the SPEED-TIP™ pulls the bit forward automatically, you don't need to lean into the drill; instead, focus on keeping the bit perfectly level to ensure your hole exits exactly where you intended on the other side of the timber.
