What’s the Best Tool to Use for Spade Bits?

Powerful cordless or corded drills are ideal for spade bits – Bosch Daredevil spade bits are aggressive, and best matched with a powerful drill. We recommend using the Bosch 18V Brute Tough™ 1/2″ Hammer Drill/Driver.

Common Diameter Sizes.

The most common sizes are ¾“ and 1“ diameter, however the Bosch Daredevil spade bits are available in ¼“ through 1-1/2“ diameters.

Bosch Daredevil spade bits are available in an extended length for hard to reach applications and deeper hole drilling, a stubby (or short) length for tough to reach applications and shallow holes. Or you can simply buy an extension as an add-on to your standard spade bit length.

Common Material to Drill with Spade Bits.

These bits are designed for drilling holes through common construction lumber – both treated and untreated. They also do very well through sheet goods (Plywood, OSB, Forming Plywood)

Tips and Tricks the Pros Know.

  • After the bit engages the wood, you don’t need to push – just pull the trigger and let the drill do the work. Great for overhead drilling.
  • A side handle on you drill helps you to better control and guide the tool, and helps you handle the torque that the bit requires
  • ¼” hex extensions are available for drilling holes outside your reach
  • “Stubby” or short bits are available for tight quarters
  • Long bits are available for constant drilling outside your reach

Daredevil Spade Bits.

Bosch Daredevil spade bits are uniquely engineered to provide the following benefits:

  • Spurs – the points on the sides of the bit that stick out are for cutting through the back side of the lumber, leaving less tearout
  • Reamer – the sides of the bit are sharpened down the length – this reams the hole as it is drilling, leaving cleaner hole sides
  • Contoured paddle scoops chips out of the hole, and eject them – allowing for faster drilling
  • Fully threaded tip pulls the bit through the lumber – saving time and effort
  • ¼” hex shank allows for quick chuck engagement, and fits in smaller tools and impactors. Is grooved to reduce slippage in the drill chuck
  • Tool steel material allows the bits to drill hundreds of holes
