BOSCH ITT20215 15-Pack 2 In. Torx #20 Impact Tough Screwdriving Power Bits

Everyone seems to ask what these bits are when they first see them -- they are thin, have a silvery label, and I don't share them. When you want some daily work bits that don't round over quickly or snap, Bosch has figured out the best products in this market. They aren't quite up to Wera, but they also are 20% of the cost of Wera. So how does Bosch do it? I could say it's just German engineering (Wiha, Wera, and Bosch are all German-made), but they've figured out the metallurgy really well. Bits can be harder for better tip holding but then are more prone to snapping. They can be softer for less snapping but then they wear faster and become loose in the socket as well. What Bosch does is to use harder metal, design the shaft so it's stronger and more resistant to breakage, and then (crucially) does a better job of making the actual working tip so it fits better. Bosch bits tend to hold the screw even without a magnetic holder, and they certainly can out much less than others (looking at you, Milwaukee). If I were rating bits after tens of thousands of screws, I'd still put Wera first, Bosch second, Wiha third, and then quite a drop in quality to Makita XPS and the newer Dewalt Elite bits. Bosch, though, is hands down the best all-around bit and even more so when cost is considered. This applies to all the sizes and lengths I've used. Highly recommended.

Work great where the longer style are often needed when used on decking boards. They seem to work well thus far as I do wear these types of bits out and clearly cheaper in volume than from local big box stores.

Inexpensive and good quality bits. I have been using them without worry of damage for a couple of months now and the teeth are still looking new!

Very good product

The strength of these are great! Most screws that I use for outdoor applications have the T20 head. The t20 bit that comes with the screws are not made very well and break easily. I bought a multi-pack of these thinking they would break easily as well and would have several as back-ups. I was wrong, these are very sturdy and do not strip or break. I am still on the first bit and it is still going strong (I would estimate I have screwed in between 75-100 two inch deckmate screws so far with the first bit). I would highly recommend this brand for these bits.

Great product. Much better than the cheapo ones I had earlier. I bought a large number of them because I was doing a large deck and wanted to make sure I didn't have to stop in the middle of the project.

Got these for pistol optics and the screws that have to be torqued to a specific lbs per and they work great. Highly recommend.

Don’t waste your money on DeWalt or Milwaukee, let alone the no name “impacted rated” hits. Deck builder here, tried them all and Bosch bits last significantly longer than any other I’ve tried.
