These Bosch Spade Bits are the only bits that I use for drilling holes in wood these days. I have tried many other paddle bits in the past but I found that the Bosh Daredevil Series is on point.
I was pretty excited when Bosch sent me this 12 piece set. I already have a bunch of them in my truck but it’s about time for me to get new sharp ones - perfect timing. Most of the time I only use a handful of the sizes and the rest remain in their bag sharp is the day they were forged. Sizes are 1 1/4”, 1 1/8”, 1”, 7/8”, 13/16”, 3/4”, 11/16”, 5/8”, 9/16”, 1/2”, 3/8”, and 1/4”.
As an electrician I generally only use the 5/16” and 3/8” for low-voltage. The rest of the time, the vast majority of it, I use 1/2”, 7/8” and 1” for running Romex or feeders, and on the occasion of doing commercial construction 1 1/8” and 1 1/4” (where I need to fit multiple sheathed MC cables through one hole).
What I like about the blades is the design. Most paddle bits or spade bits are flat with a spike at the top. These do not do a very good job of removing material while cutting so they generally take longer to drill through a hole, they dull quicker, and when you hit a nail the blade is pretty much shot. These Daredevil Spades by Bosch are shaped in a wave on both sides, which aids in removing material from the hole that you’re drilling. The tips on the sides are designed to not break off as easily when hitting a nail, and the center spike at the tip of the bit his spiraled like a screw so it helps pull the tool through the material rather than you having to push so much.
As long as you take care of your bits and your blades they will last you a long time. The major cause of bits and blades going bad is from heat as well as hitting objects that are not meant to be drilled through. As long as you don’t do those two things any bit or blade that you use will last you a very long time. But we all know things don’t always work out that way. But I promise if you baby these things they will continue busting ass for you for a long time to come.
I give these Bosch spade bits a five star rating because I use them every day, and nothing else has come up yet that is any better in my opinion. These do the job extremely efficiently and reliably, and as an electrician I am extremely happy to have them in my tool pouch.
