Bosch DareDevil Spade Bits - Review
Bosch is known primarily for their tools, but lately they've really been making a name for themselves in the accessories market. Anyone who has used tools for a while knows that blades and bits are just as important as the tool that they're seated in. Tools are sort of a 'weakest link' scenario; a great drill with a dull bit is only going to be as good as the dull bit. We've been testing out the Bosch DareDevil Spade Bits and can now say that if you put one of these in a great drill, what you have is a relentless wood eradication system.
The primary difference between the DareDevil Spade bits and your standard spades bits is this little threaded nub up at the centering point. Once these threads catch (which they can't not do), the bit is actually pulled into the wood. This happens with so much aggressiveness that we practically felt in danger of dislocating our shoulder while drilling holes. The body of the spade is also contoured so that the shaved wood doesn't clog up the hole and bog down the bit. The pointed spurs are additionally designed to minimize blow-out (which is better than most spade bits, but still considerable). There's a lot going on with these little bits.
The bottom line is that the Bosch DareDevils absolutely devastate lumber and if you're looking for some real fireworks, put one in an impact driver. After a couple of minutes it'll look like there's a pileated woodpecker living in your workshop. We spent about 30 seconds on a pressure-treated 2x6 drilling maybe a half dozen random holes and, as you can see from the image, the results are serious.
The only issue that we could find with these bits is that you can't just pull the drill out of a half-drilled hole, you actually have to put the drill in reverse. Once the centering threads catch and the connection to the wood is made, it's over. This is hardly a drawback, but just something we had to get used to.
If you're an electrician, carpenter, whatever really, we suggest checking out these bits. If you're a deck builder, just stop what you're doing and find some as fast as you can, and make sure to get the extension so putting holes in 4x6s won't be a problem.
