1/2IN X 16IN Spade Bit DW1591-SBD

Dewalt's professional-grade 1/2-inch x 16-inch Spade Bit engineered for rapid wood boring and precision drilling through thick lumber. Featuring a heavy-duty, full-length, heat-treated shank, this extra-long bit is designed to resist bending and breakage under the high torque loads required for deep structural holes in framing, electrical, and plumbing installations.
Key Features
Heavy-duty heat-treated shank provides maximum durability and protection against bending or breaking during high-stress, deep-hole drilling.
High-performance cutting spurs scribe the wood surface for an optimum hole finish with significantly reduced breakout on the exit side.
Extreme Speed Channel design facilitates faster chip removal, which prevents clogging and improves overall drilling efficiency in thick timber.
Universal 1/4-inch hex shank prevents slipping in the drill chuck and is fully compatible with all standard quick-change systems and impact drivers.
Chamfered corners provide enhanced durability and bit life, particularly when encountering nail impacts during rough-in applications.
Integrated hang hole allows for convenient workshop storage and serves as a practical attachment point for pulling wire through bored holes.
