Customer Reviews for Milwaukee SHOCKWAVE IMPACT DUTY Titanium Twist Drill Bit Set (23-Piece)

This review is for the Milwaukee 29 piece Cobalt drill bit set (Model 48-89-2332). I was granted a chance to test one of these kits out, and it’s proving to be a welcome addition to my tool box. I’m a homeowner/DIY’er, not in the building trades, so my review is from the DIY viewpoint. The 48-89-2332 kit includes: (1) 1/16", (1) 5/64", (1) 3/32", (1) 7/64", (2) 1/8", (1) 9/64", (1) 5/32", (1) 3/16", (1) 7/32", (2) 1/4", (1) 5/16", (1) 3/8", and (1) 1/2" bits. It's nice that they include the extra 1/8" and 1/4" bits since those are frequently used and liable to dull first. All of the bits come in a nice hard plastic case, in red with the standard "Milwaukee" logo in white. A couple of notes about the case - the thing came encased in the usual clamshell plastic packing box and I had a difficult time getting the drill set out of the clamshell. I used a utility knife and wore gloves - the clamshell edges are very sharp. YMMV. Once out of the packing you'll see that the 1/2" bit comes separately from the Milwaukee case (so as to be prominently on display in the clamshell), but there is a hole in the Milwaukee case for the 1/2" bit along with all of the others. In the photo attached you’ll see the bits are in two rows on each side of the case. The back row bit size can be difficult to read without removing the bit in front. When new the bits can be a bit sticky to get out and back in but as the bits are used the case “wears in” and taking bits out or replacing them becomes easier. The case measures (when closed) 7 ¼” wide, 3” deep, and 4 5/8” tall. It has a solid clasp to keep it closed (see attached photo) and small feet designed into the bottom of the case. There is no carrying handle on the case but it can easily be grabbed with one hand. The Red Helix bits themselves offer a 135 degree split point to reduce walking on hard surfaces. The Cobalt drills are designed for hard metal use: stainless steel, high alloy steel, cast iron, and wood. I’ve used a Red Helix bit (not from this kit) to go through PVC piping and it worked just fine. In this kit the bits that are larger than 11/64” have a “Chip Breaker” designed in, to help reduce heat buildup. Seems to work, no complaints. I’ve not run into anything around the house or yard that the Cobalt bits can’t handle. (I should note that I use the bits in cordless drills and in a drill press and get good results either way). The bits (except for the very smallest ones) offer flat surfaces that will help secure the bit in a drill chuck. Also the bit size is, of course, marked on each bit – but can be hard to read because the markings are the same color as the bit itself. (See photo below). The bits run true, I’m not getting any wobble from them, and running them through soft pine doesn’t seem to leave any jagged edges on the reverse side of the wood. The bits are infused with a cobalt mixture, they’re not coated. That means that the bits can be resharpened if required without ruining or removing any coating (such as some titanium bits have). Of course when going through hard metal it’s wise to go slowly and use a quality cutting oil. Note that these bits are NOT impact rated – they’re not designed for use in “hammer” mode in masonry. For home use the 48-89-2332 offers a comprehensive range of sizes and buying the kit is less expensive than buying the bits individually. Of course some of the bits in the kit may be sizes you’ll never use – but it’s always nice to have your bases covered, “just in case”. There are certainly cheaper bit sets on the market, but I’m getting good service out of the Milwaukee Cobalt bits and “cheap” and “value” don’t always go together. If all you do is occasionally drill into drywall to hang a photo frame or two, then this set may be overkill for you. If, however, you perform household repairs on sinks, siding, cabinets, HVAC, plumbing, etc. then the Milwaukee kit may be right up your alley. For most of the jobs I do the Cobalt series is overkill; however they get the job done without fuss and when I do have to drill into a stainless steel sink top or some such repair they’re up to the task. HTH Regards, Jim

The drill bit itself worked well, but the 1/2" bit sheered off from the chuck area the first time I used it to drill into an aluminum tube. Aluminum is much to soft to have caused this bit to snap, especially on its first use. The smaller bits have held up better, but considering the fact that the largest bit, which played a large part in my determination to buy the kit only worked once, I can not recommend them. I expected better from a Shockwave set.

The Milwaukee Shockwave Impact Duty Titanium Drill Bit Kit (23-Piece) is a nice collection of high quality drills for use with both impact and standard drills for masonry, metal, wood and plastic. These drills are coated with a hard coating of titanium and have a more shallow 35 degree cutting edge to minimize initial walking. The larger drills have what they call a chip breaker to decrease heat buildup and consists of grooves cut in the face of the bit which I don't understand just how it works. The helix refers to the angle of the drill turns that moves waste chips up and out of the hole and these drills are designed to run cooler by varying the angle. It all sounds like advanced stuff whose proof is in the using. I do like that the set includes doubles of the smaller most used size drills which always wear out or break first. I've tried these out on some scrape hardwoods and they bite cleanly and easily did their job. The case is normally not worth mentioning except with this one, its sturdy has a good lock mechanism and strong hinges, should last the life of the set. I have a number of drill sets and this is going to be my go to one for most jobs.

The 1/4" shank on these rust terribly and you are no longer able to read the laser etched size on these. Horrible bits and will not be buying these again.

Milwaukee tools, in my opinion, are far superior to other brands. I have two of these driver bit sets, one for home and one for work. The pack out box makes storage a breeze and it's lockable and durable.

Great bits, worth the money

burned up 4 bits drilling out cheap bolts

This was a great value on sale!

Great price for what you gett. The case helps to organize everyting and works with the Milwakjee packout system. Lots of various bits to cover all of my needs.

Very usable small drill bits

These bits work on metal much beter then the standard gold bits. My only improvemnt would be giving them the 1/4” hex end so the can be quickly inserted into a an impact chuck if need be, although they should be used in a drill, the option would be nice and the hex ends bite better in a standard drill chuck.
