Wera 057656 #2 x 50mm Phillips Impaktor Diamond Coated Power Bit

Strongest bit for impact use. Not the "God" bit but takes abuse in stride. If you are tired of constantly changing bits try this one.

You can't go wrong purchasing these bits. Great product and will stand up to a lot of usage. I'll purchase these again.

great bits,and love the easy to read shaft.

These are my go to bits for my impact driver they haven't snapped on me yet and they got a really good grip. Dope ness as always with wera

Wera Quality, no need to say more

Nice to have it to use. the center is accurate without variation

There is absolutely no diamond coating as far as I can tell, so the line about them aiding grip is total BS. Still, they wear longer than Dewalt impact bits and I haven't broken one yet.

Durable and ease to find.

I was using milwaukee shockwave bits but wasn't satisfied with the fit, how much they deformed and how much wobble was in the shaft. These wera bits are made to tight tolerances and fit in stainless hardware very well. They spin true in the chuck, no wobble. My only gripe is that they explode a lot sooner than the milwaukees. I deal with a lot of stainless fasteners stuck in corroded aluminum and my M18 and M12 impacts will kill these bits after a couple hundred uses. The upside is that the tips keep their shape to the very end and don't destroy screws. I might buy more in the future but only after testing out some wiha bits too.

this bit takes a good beating with stubborn screws i've been working with!

Very tough bit.

Impaktor bits are well made and worth the money. Hard on bits and this made an immediate impact on my jobs. Support KC Tools real company selling best tools available

Excellent service and product

I feel much more confident using these bits, they also save money as they resist rough handling

I do not drive screws all day for a living. However, I drive screws a lot, and when I have to use Phillips instead of Torx or Square, I prefer these bits because they last a long time, and they help the screws last a long time. - - I can fantasize about bits where the shank is HVOF sprayed with 15 microns of nickel alloy 625 for corrosion resistance and the tip is a micro-roughened diamond - nanocrystalline SiC composite, but the best bits I can actually buy are these.

I use more Pozidriv and 1/4" hex than Philips, but it is always good to have decent bits around "just in case", and these fir that bill.

I have been using this bit since last week, and I really like it. Screwed around 1.000 different kind of screws with impact drivers and it seems very good. Well designed, strong, perfect fit, etc. It is early to say this is the best power bit what I have ever had, since I've used it for a short period of time, but this one is my favorite 2" bit so far. - Note: The diamond powder tearing off quickly, but I am giving 5 stars because of everything else is outstanding with this bit.

We repair equipment all day long, so far its been a week and now damage to the bit or the screws. Due to excellent fitment.

When I received the bit, I thought they sent me the wrong one! I looked at it and said, "where is the diamond?" Then I put it under a microscope and then I could see. It is a very fine diamond dust that is vacum brazed onto the tip. Why so fine? Big pieces break off. I put the bit in my Bosch 18 volt impact or and ran 30-3 inch screws as far as they would go into a seasoned yellow pine board. The bit performed extremely well! The diamond particles gripped the screw head and kept the bit from slipping. Bits start to strip out when they slip even a little. (1/1000s inch). It moves the metal around on the tip. It does not happen with this bit! (Eventually the diamond coating will wear out, but it lasted very well in my testing. I also tried the terminator bit. It was good steel, but the diamond Impaktor bit blew it away. These are EXPENSIVE, but if you have the money, they are great.)

These are outstanding impact bits. Have used them before and have had nothing but success.

It took me a wile to decide to buy those but I'm happy I did! Nice bits...scary thin. - Now all I have to do is start buiding my new deck! - Hey KC Tools thank's for the gift! (#2 philips bit)

These bits are of high quality and will outlast your usual bits that you get from the store.

simply put this is the best bit i have used. im a installer and use a impact drill all day .this bit does not strip the screws or the bit. the best

The Wera bits work great. I have been using this one the past few weeks. Wanted to give it a try, I do not see much difference, I do not have a impact drive tho, so that could be the difference.

Awesome
