Within the Milwaukee Shock Wave series of Impact Duty Bits, T15s are offered in a 2 pack of 3 ½” length. The bits are designed to fit ¼” hex impact drivers, ¼” Drill driver chucks and quick-lock ¼” chucks. I evaluated their application with both a quick-lock chuck and a 3/8 drill chuck. Size is engraved at the base of the bit shaft. Milwaukee has a branded name for their wear guard tip which boasts a 50x’s longer life than comparable bits. The T15 head is about the same diameter as the bottom half of the bit shaft. The area just behind the tip is noticeably smaller in diameter than the rest of the bit body. This forward area of the bit shaft is designated as the “optimized shock zone” designed to absorb peak torque and thus prevent early breakage. The shock zone is marked in the Milwaukee trademark red for easy reference. The composition of these bits is Alloy76 steel, engineered to life extension of the bit. This product is distributed by Milwaukee Tool, manufactured in China.

I'm a big fan of the new-fangled "Engineered" self-drilling, self-tapping screws make by GRK and others. I keeps several sizes and types on hand. I probably never will use up my boxes of old-style Phillips Head screws. I especially like the "Headless" Trim Screws made by GRK. The problem is cam out. The Torx T10 bits that come in the boxes of screws don't hold up long. The star teeth wear down and I'll strip out the tiny head of a "headless" fastener about halfway in. Great. Break out the rotary tool to grind it away. Milwaukee makes 2" long T10 bits with Wear Guard Tips, Alloy76 and Shock Zone torsion features to battle the dreaded cam out problem. This is mission critical when using these headless trim fasteners. I like these way better than the bits that come with the box of screws.

Milwaukee shockwave 2 inch #T15 Torx bits These T15 shock wave wear guard tips are impact duty and made from custom alloy steel to grip better and last a long time over 50 times longer than some other tips. I have worn out/striped other brand tips just using them by hand. The tips fit great and I no longer have to worry about strip out and they are impact duty.Get these and other great Milwaukee tools at Home Depot on line or in the store They work for me

Another great product from Milwaukee, this Shockwave Impact Duty 3 1/2 inch T-15 Torx Alloy Steel Screw Driver Bit has some new features, Wear Guard Tip (TM) which increased wear resistance, that protects the fit over the life of the bit. The Alloy 76(TM)Steel is customized and heat treated per tip type to extend the life of the driver up to 50X. Also you have the Shockwave Impact Duty bit that optimized each tip type and length of driver bit to absorb peak torque and prevent the bit from breaking. These tips are also Laser hardened and the bits are Laser etched size for identification. This is the reason that I chose this product to use in my workshop.

The MILWAUKEE® SHOCKWAVE™ 3.5" T-15 Impact Duty™ Bit is designed to be one of the most durable, fitting driver bits on the market. The Phillips bits feature Wear Guard Tip™ for increased wear resistance, which protects the fit over the life of the bit. I love that the impact driver bits have an optimized Shockzone™ for each tip type, and the length of driver bit helps to withstand the torque which helps to prevent breaking. Many of my longer bits have either stripped out, bent or have broken during hard torque. These bits are made of custom Alloy76™ steel which is heat treated per tip type to extend the life of the driver but by up to 50X vs. competitive impact driver bits. Once my old bits break or wear out (which is usually after one or two uses. I switch to the MILWAUKEE® SHOCKWAVE™ Impact Duty™ driver bits. They are consistent every time I use them. These bits are a must for the professional craftsman along with the novice DYI!

Milwaukee is one of my favorite brands from decades of experience with their quality. I own several Milwaukee tools as a result. I recently got an impact driver (not Milwaukee - Rigid, but for a good deal) and wanted to get some good drive bits to complete my set. I really like the design of their bits and the different lengths they have to accommodate different situations. These bits are long wearing and well designed ergonomically.

Strong bits. I am building a deck and the special lag screws required by code, if needing to apply fascia requires this bit. You are provided thr bit for the lags in thr package but it's junk and burns up quick. These bits worked perfectly and extended longer using them in 20+ 8inch specialty lags, these show no sign of wearing down, where the ones provided were tossed hourly.

These bits are good for exactly one screw
I bought these to drive 1/2" long number 8 sheet metal screws. Each of the five bits broke on the first screw I used it on. I don't agree that these last "30x longer than typical tips" when the tips break off on first use. I would say less than 1/30th the life of typical tips. Maybe I got a defective batch, but what I got was junk.

    Milwaukee Torx bits perform well above any phillips, however, they like others, when used extensively, need replaced often and all sizes should come in larger packs of 25 or fifty, not just for price but convenience.

    Milwaukee SHOCKWAVE Torx #30 3.5 in. Impact Duty Steel Screwdriver Bit (5-Pack) review: Another outstanding Milwaukee product! I usually use a magnetic bit extender and change bits in the head of the extender. This is my first time to use a Torx solid bit on a long shaft without the need of a magnetic bit extender. While this does eliminate the advantage of a magnetic 'sticky' it is quick and fast and handles the demands of an impact driver. This would probably be just the ticket for putting down Torx deck screws! I used it and am quite pleased with it. The bits do seem to last an extremely long time! The size of the bit is labeled very clearly so it is easy to pick out in a toolbox container. Very glad to have this additional, useful and powerful tool! There ya go!

      This 5-piece pack of Milwaukee Torx bits (Model 48-32-4578) may well be the last set of #20 Torx bits you'll ever buy. The “Wear Guard” tips fit tightly in the screw head, and haven't shown signs of any wear after dozens of screws driven into hardwood – even used with an impact driver. There is virtually no slipping, though I have seen metal filings coming from the screw itself when I intentionally allowed the bit so slip. The 1/4” hex shanks fit firmly in every tool I use and there is very little “wobble” of the bit. The 3 1/2” length is perfect for most applications, but 2” bits are also available when shorter length is needed. At less than $1.60/bit these are a great value!

      These Milwaukee bits (model 48-32-4687, package of 5) are a perfect compliment for large (T30) Torx head screws. The “Wear Guard” tip is seemingly indestructible, showing no sign of wear after driving dozens of large screws into pressure-treated lumber. They fit tightly and rarely slip, even driving screws below the surface using the impact drill. The hex shank fits firmly into the driver, and there is very little wobble of the shaft. I like this shorter 2” length for the larger T30 screws, as it gives a bit more control, but other lengths are available. I suspect the 5 bits will last me for many, many years of deck building, fence constructions, and general cabinetry work. These bits are great quality at a great price.

      If you want a bit, a torx bit that is built tough to last longer with a little bit more of a "reach" then this is the one you are looking for. Milwaukee makes tools that last and this is no exception. They are very finely and accurately machined and when inserted into the torx fastener or screw there is no play at all. The tips are designed so that they will go into the screw as deep as needed. The 2 inch lenght will give you a little more reach than a standard size bit. The fit all 1/4 inch chucks and they are also compatible with drivers with a locking, quick release collar. For home or on the job these are going to last a long time.

      A 5 pack of Torx T10 sized 1" long driver bits for any 1/4" hex shank equipped tool, including impact drivers, and made from a hardened steel alloy with a shank capable of "yielding" slightly to external forces without losing its original shape and properties. This means it will survive much longer than average when subjected to the punishment that impact drivers dish out. The business end is also machined to higher standards than average to ensure a secure grip although it probably should be noted that the quality of the screws being driven figure highly in the success of the end result.

      Milwaukee has totally innovated theT20 Torx Screw driving bit. My new choice for wood screws are Torx type screws and using a MILWAUKEE® SHOCKWAVE™ Torx #T20 3 1/2" Impact Duty™ Steel Screwdriver Bit. These bits have a laser hardened tip which is designed to extend bit life by a factor of 50. The precise sizing of the tip head fits a Torx Screw snuggly which prevents stripping the screw head. For me this has always been a problem when seating a Phillips wood screw. The ¼ inch hex end of the driver bit is laser etched with the size T20,T25 etc. The size of the Torx screw is typically shown on the box of Torx fasteners so you always know what size of driving bit to use. The Torx bits work well in both1/4-inch hex impact drivers and/or keyless chuck drill drivers. I would recommend these bits to both the DIYer or professional craftsmen.
