Just as an FYI, to my knowledge “impact rated” has very little to do with the strength of the bit and everything to do with how it fails. The idea being that you don’t want a bit that is under the extreme pressure an impact driver can cause to explode the way a hard metal would (such as d2 or s2). Impact rated bits are made of softer metal that is more prone to flex and will fail more controllably by twisting the metal. Some manufacturers have embraced the twisting of these bits to claim they can produce more torque… Read more »

I tried Bosch, Milwaukee impact, Dewalt impact/ regular, Cobalt, Makita black impact. There all junk/100 screws. Home Hardware has these red bits/ $4+ each their not bad. Makita cheap grey bit/ kits seem to last the longest/400 screws and there isn’t much difference between the Makita cheapo’s and the Makita Gold. If the Makita Gold bit slips due to paint in the screw (colored deck screws) it will last as long as the Makita cheapo’s, if the Gold bits don’t slip due to paint they may last 800 screws.

Hi, I bought a Vermont 3 1/2″ #2 Robertson in 01′ at Building for $2.45 It came in a little package. I put in about 15,000 various length screws using a 12 volt Makita drill with 1.3 AH red battery. The bit finally started to slip when I built an 8000 square foot deck. I tried every bit going since then. None last more than 200 screws heavy use. The Makita gold ones at Home Depot for $20 seem to be the going these days but they still aren’t as food as that old Vermont bit I had.

Good article thanks. Often an overlooked aspect.
