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.

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.

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.

The bits are very sturdy, fit into the screws very firmly, and are very reasonably priced. I've used the bits for awhile with no signs of wear from usage. I prefer the 3 1/2 inch length but Milwaukee has shorter bits if you need a shorter bit.

The Milwaukee Shock Wave 3-1/2 inch Torx T15 Screwdriver Bit is a sturdy bit. I prefer bits in the 3 1/2 inch length for most of my work, of course I will use shorter ones for tight areas. The bit fits a T15 screw very securely with no slop and resists the bit rounding off if you aren't quite fully locked in. The wrap around the shaft was a bit loose but it didn't affect the bit. The next time I need to buy a screw driver bit, I will look at Milwaukee first.

I'm very happy with this pair of bits. They are created true to size and will fit perfectly in a #3 size phillips screw. Its quite handy having some of these bits around; they aren't bulky like bit holders and can fit easily into all kinds of places. The tip is very durable too; it hasn't worn down at all since I got it. I'm not impressed with its ability to hold screws magnetically, but it doesn't advertise that it can, so I can't hold that against it. This is a good pair of bits to have.

This is a great pair of bits. True to their size, they fit in #3 screw heads very snug. I really like how long the bit is. I can reach into all kinds of places that I couldn't before. Extension bit holders have wide bit receiving ends which inhibits the ability to reach narrower holes; this bit doesn't have that problem. The bit is also magnetized. Some bits like this advertise they can, but little can actually hold a screw; this one does a good job of it.

The concept of having the bit shaft absorb excess energy is a good one. I have had fasteners broken by impact drivers and also had fastener heads stripped by impact drivers and metal bits. These are a good length that will fit many uses. Milwaukee advertises these as having wear resistant tips and custom designed shafts to manage the energy created by impact drivers. They also say these will last 50x longer than standard bits. I'm looking forward to that!

These bits have some nice features built into them. First of all there's the "Wear Guard Tip" that extends the life of the driver blades. The "Wear Guard" treated tip should last fifty times longer than a untreated tip. And then there's the "Shockwave" shank that's designed to mitigate instantaneous over-torque. Instantaneous bit shocks on a normal bit causes premature rounding or shearing of of the bit blades. Will it be the last bit I'll ever have to buy? Maybe not but they have the built-in technology to last a very long time.

I didn’t get into anything too heavy with these bits like repetitive screw driving. I sunk a few 5” T-15 trim head screws for a gate mounting block on my garage with the impact and I used it in a regular drill while putting my shutters back up after painting them recently. I didn’t encounter any slippage, stripping, or cam out of the bit tip during any activity. With deeper trim head screws there’s pretty much no deflection and the bit fits in tight with no wobble. The pan head style I used for the shutters seemed to have a lot more play, but I didn’t have any issues with slipping or stripping heads either. I like the extra length of the bits the best since most standard 1”- 1-1/2” bits can’t get to recessed screws. I drove at least 50 screws and the tip isn’t even marred up yet, so these should last a while.

I ordered the 2-pack of Milwaukee SHOCKWAVE 2 in. Philips #2 Impact Duty Alloy Steel Screwdriver Bit to replace the bits I have been using that had a tendency to wear out after a short time. I have used one for several jobs and the tip looks brand new indicating that the durability will be superior to my old bits. The fit into the screws has been excellent. The chuck fits easily into my conventional drills as well as my impact drill. These are now my go-to bits so the red shafts are handy, making them easy to find in my tool box.

These 3 inch Milwaukee Shockwave impact duty T25 Impact bits worked better than I expected. I decided to open up this new package even though I had an older T25 bit that never gave me problems. I compared the quality and efficiency of my two bits upon my daughter's old bed which I needed to disassemble. The Milwaukee bits felt smoother removing the screws in addition the bit head felt more snug and did not once slip out of the screw. I did like the longer size of these bits as it made it easier to reach a couple of screws. I put one bit in my drill bag and keep the other on my work bench at home

Hi all, I bought these bits because I own an old motorhome that is riddled with these square head screws. When I must tar the top or repair a siding I must unscrew literally hundreds of these little screws. I used to have a manual screwdriver & man, would that take forever. I also own a Milwaukee screw gun that these bits fit into perfectly. Now it doesn't take anytime to pull paneling. I suggest you get these bits if you are in a similar situation. They really take a lot of work off your back.

Milwaukee SHOCKWAVE 2 in. Philips #3 Impact Duty Alloy Steel Screwdriver Bit (2-Pack) The bit is ...
Milwaukee SHOCKWAVE 2 in. Philips #3 Impact Duty Alloy Steel Screwdriver Bit (2-Pack) The bit is 2” overall in length. It is a blunt nosed #3 Philips size. The blunt nose has a shape of a square near the center and cross wings that fit the Philips screw head pattern. The square shape increases the grip and the wings allows you to be off vertical by a little when starting the screw into the surface. The best orientation is directly parallel with the screw. I had #12, #14, and deck screws that this bit fit perfectly. Played with about 40 cycles of screwing in the screws and then removing the screw. No problems. There are features of the Bit: 1). the specially designed covering on the tip that helps prevent the tip from deforming from the perfect fit. 2). The red center section that will twist (slightly) if the screw jams in the wood while in a drill motor. Without the twisting, the screw could break off. 3). The heavy metal base that inserts into the drill or wrench is also designed not to break under the force applied for screwing. You can use a wrench with this bit, but you must apply significant pressure to keep the bit tip in the screw. Too little insertion pressure will allow the bit to round the screw head pattern. The 2” length is nice when you are in areas that have restricted clearance. Short bit plus the length of the drill body can limit you between studs or between obstacles. I have some towel racks and toilet paper holders that have covers that are like a 3” deep cup. You put the screw into the cup and it goes out the bottom and into the wood. The bit that was 3.5” long was a necessity for my Delta Shower bar. This series of bit comes in a variety of shapes and lengths. Nice tools.

As an avid woodworker and DIY guy I have tried a lot of different screwdriver bits over the years, hands down these Milwaukee Shockwaves are some of the longest lasting toughest bits I've been able to find. For most projects I find the longer 2in length is more useful than the shorter bits and better than dealing with the magnetic bit holder that constantly results in bits coming out when they got too much bite in the screw.

It is nice to have the option of buying just 2 bits for a specific project or if you want to try a new line of products and not having to buy a complete pre-made set with many different tips. I like the Shockwave precision Phillips Head edges on this bit. It seats nicely into the screwhead without any wiggle. The bits are clearly labeled at the end of the bit shaft, making it easy to pick the right bit when it is mixed in with other sizes. When working with recessed surfaces or countersinking a screw, I prefer the 2-inch bits when compared to the 1-inch bits, they give me clearance from the Chuck Body and Jaws. The 2-inch bit sticks out 1.375 inches from the chuck jaws. (See image Below) I used a tool magnetizer to make my bits magnetic for holding screws. I find this is a better solution when compared to using a magnetic bit tip holder. When you purchase Milwaukee products you have an expectation that the products will be well made and work as expected. These bits worked extremely well.
