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.

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.

Bosch is the best hands down. We do PVC decks and these get a work out. hold up well and don't cam out

These Torx bit work, but they are a bit loose in the deckplus screws that I use more often. I'm concerned about their longevity. I have used one bit to drive in about 30-40 screws when building a wooden fence. And they did work without issue, it is just that I wish they were tighter fit. See my video where I show how nice and tight the T25 that came with the screw box was as compared to this brand. When I got my dewalt T25, it was tighter, but I have used it to drive 500+ screws when I rebuilt my deck. It is now a bit loose like this one. So if Bosch is starting this loose to begin with, I’m wondering how long they will last. But the Bosch brand does cost less and still works. So it is a good value. Even if they go bad, I got a box of 10 (dewalt brand would cost me the same for just 2 of these bits). I paid $7 for 10 Bosch T25 bits.

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!

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.

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.

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

Very good I use everyday as an automobile mechanic. Works great with electric impact

These are the perfect shape and size for installing hidden clips on composite deck boards.

À date ce sont les embouts qui me sont les plus résistant! Enfin, fini les têtes grugées.

The length of the shaft makes these bits idea for framing.
