Anyone tried one of the Bosch Daredevil spade bits? I just did at my
local industrial supply's open house. The Bosch rep introduced it as
something that would change my life, and had me drill a couple test
holes. The daredevil bit has a full screw thread on the end of it rather
than threads cut on the sides of tip.
The bit also has a different cutting profile than standard spade bits,
where different parts of the bit start cutting first. This makes it very
easy to drill a hole through wood, and the resulting hole is fairly clean
The effort required to advance the drill is minimal. Once the bit has
started, the only effort required is to keep the drill straight.
On the one of test holes I drilled, the hole quality seemed on par with
the sharp spade bit. Both were good quality holes, it'll be interesting
to see what happens as the tool inevitably starts wearing down.
One negative, however, is the bit needs the reverse capability of the
drill to cut a partial hole.
I don't know about it changing my life (not the way the impact driver has
anyway), but it's really neat.
Never teach your apprentice everything you know.
