Bits did not last
I was removing deck screws from composite decking attached to treated pine joists using an impact Bosch driver. Of the five bits that I purchased the tip broke off of four of them and the fifth one became unusable after removing around ten screws. The project is still not completed.

    Absolutely the worst
    These are the worst bits I've ever used. Milwaukee should be ashamed. Both bit end twisted driving screws into soft southern pine 2 x 4's. These two bits drove a total of 6 screws. Fifty times life my butt. Don't waste your money.

      Stripped
      Will not hold the torque of driving long screws. I was driving 3 1/2 inch long screws with these Milwaukee square bit drivers. They Kept stripping out driving screws into softwood at that.

        Amazing Screwdriver Bits
        These screw drivers are amazing. They come in packs of two. They are sturdy and fit the screw heads securely for easy drilling. They fit many types of screws, so it makes the job quick and easy. They are steel and made with unique heads so getting the job done quick requires very little effort. I didn’t imagine that this tool would do the job so easily. It is well made.

        Strong, long lasting bits
        I’ve used many different brands of driver bits in my impact driver and most seem to last about the same before rounding out and no longer gripping screws well. These Milwaukee bits are the second set of these and I am definitely going to get more in all the sizes I typically use. These bits fit the screws tightly and typically last about two times longer then other brands I’ve used. The 2” length is perfect for most applications but longer bits are also available. Overall I’m very happy with these and will continue to pick more up as needed.

        Phillips drivers are a good choice with fasteners. Since the invention of this type of bit, you have more control in regards to pressure of force on the actual fastener. The actual length of these drivers, I find works well with most jobs at hand. For extra reach, I always keep an extender at hand. The coating on the bit itself, keeps rust and corrosion at bay for a long time. I find that if you pay attention when inserting the bit into the driver head, making sure that it bottoms out, creating reduced wear on the tip, therefore prolonging it's useful life.

        Many many moons ago, there was only Phillips and Slotted for our choices with fasteners. Since the invention of this type of bit, you have more control than ever before in regards to pressure of force on the actual fastener. No more standing on the drill so that the bit does not tear out the head of the fastener. The actual length of these drivers, I find works well with most jobs at hand. For extra reach, I always keep an extender at hand. The coating on the bit itself, keeps rust and corrosion at bay for a long time.

        I’ve used many brands of drill/driver bits over the past few years snd while some have been better then others, none really stood out as being really durable. The tips all tend to wear out pretty quickly snd start stripping screws. I decided to give these Milwaukee bits a try. I really like the extra length of the 3.5” vs the traditional 2” bits that most kits come with. This allows better reach especially in tighter areas. These bits inserted and withdrew from my driver easily without snd binding. I found them to engage the screws nicely and without slipping. While I have only used these a few weeks, I have not seen any noticeable wear and I’m confident these are going to last longer then other brands I’ve used in the past.

        The Shockwave impact duty 3 1/2 square drive driver bit is a nice additiion to my power tools. I have a kreg pocket screw jig that I use constantly and this driver works perfectly with the special pocket hole screws. I have used these in both my drill/driver and in my ryobi cordless impact tool and it fits the bill perfectly, I feel like I am more in control of the torque I apply to the screws.

        These are great bits. I really like the length and the durability of them. I've got a dewalt impact driver that I use but I like the Milwaukee bits better than the dewalts so this is what I get. One thing to note. In the package or out of the impact the length is 3.5 inches. But once you put it in the impact driver half of an inch goes into the driver. So if you are trying to reach something in a deep hole deeper than 3 inches it wont reach. Thats my only complaint other than that they're amazing bits.
