    Q:Is this a magnetic bit

    Answer This Question

    A:  Not really, not magnetic enough to hold an 1x3/4 inch construction screw. Which for me is a deal breaker.

          Poor Quality
          I drove about 8, 2” t-10 screws before the tip was twisted. Went to grab the other bit in the 2 pack and it’s a t-15 with t-10 printed on it. Disappointed, definitely not worth it.

            Tip of the bit started twisting after less than 20 screws. Maybe that is the design, but I was disappointed.

            point twisted
            I owned this 2 pack for all of 2 days. First day the tip of the bit twisted. I turned down the torque on my drill. 2nd day the same thing: twisted tip. This was not due to abuse. Did not even notice when it happened, except couldn't drive the next screw. Compare this to the single GRK bit I used for the last 3 months, on the same project. The metal is just not hard enough.

              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.

                  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 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.

                  Wear guard tips last Received item in good condition. The wear guard tips last quite a while. I have driven hundreds of screws before installing a new one. The bits lock into my impact nicely, easy to change. If you use a drill motor, they are equally easy to use. I prefer the Milwaukee wear tips after months of abuse, they hold up better than most brands. Its easy to damage one if you don't hold or place the bits correctly. This is user error, not the company's fault. Make sure to pull your hands away after starting, it's easy to slip off and punch a hole in the wood or worse yet your finger.

                  MILWAUKEE SHOCKWAVE IMPACT DUTY 3-1/2 IN. T25 TORX ALLOY STEEL SCREW DRIVER BIT (2-PACK) These Milwaukee torx bits are very strong, and drive with no vibration or wobble. I drove 4 inch screws with no problem, or slipping. The 3 1/2 inch extension on these bits are also very handy, it allows you to get into reach situations you could not with the short ordinary bits. I was very impressed with these bits, and will continue to buy and use.

                  The Milwaukee Shock Wave 3-1/2 inch Torx T30 Screwdriver Bit comes in a package of two bits. I prefer bits in the 3 1/2 inch length for most of my work, but of course I will use shorter ones for tight areas. The bits are very sturdy, fit into the screws very firmly, and are very reasonably priced. They are for a larger screw but the Milwaukee bits work well regardless of the size.
