Tool Storage
Milwaukee PACKOUT and Shockwave Bit Holders: Two Workshop Upgrades Worth a Look
Milwaukee expands its PACKOUT accessory lineup with Shockwave bit holders that mount directly to M12 and M18 tools.
Introduction
Milwaukee has quietly expanded one of its most popular accessory lines, and the additions are aimed squarely at people who already live in the brand’s tool ecosystem. Two items stand out: the Milwaukee PACKOUT storage system itself, and a new set of Shockwave bit holders designed to work both inside PACKOUT boxes and directly on your tools.
Why the PACKOUT System Stands Out
The Milwaukee PACKOUT line is the number one selling modular portable tool storage system, and the ecosystem is a big part of why. Beyond plain boxes, there are radios, lights, and all kinds of add-ons that clip into the same locking platform, so a single setup can grow with your needs.

If you already own even one PACKOUT box, the value of the system comes from how everything interlocks. The new accessories announced alongside it follow the same idea: small, affordable pieces that make the bigger system more useful.
Shockwave Bit Holders That Mount to Your Tools
The most interesting of the new items is the Shockwave bit holder setup. At first glance it looks like a standard bit holder, but Milwaukee designed it so the holders can be removed from their case and attached directly to your drills and impact drivers.

The trick is in a few small holes molded into the holder. You screw it into the belt clip position on an M18 drill or driver, and suddenly your bits ride on the tool itself. The same works on M12 tools, where the belt clip mounts sit a little higher on the body. That means no more fishing bits out of your pocket or leaving them scattered across the bench.
The holders also clamp into the top layer of a PACKOUT box, in the cup-style compartments, so you can organize bits inside your existing storage and pull them out when you head to a job.
Prices and What Fits Your Budget
The new lineup spans a wide range, from small bit and drilling sets starting around $9.99 up to roughly $15 for most holders and cases, including the customizable medium compact case for impact driver accessories. Prices run roughly from $1.49 to about $15 depending on the item.

Milwaukee has been expanding its accessory lineup steadily, and affordability is clearly the pitch here. These are not new power tools, but small organizers and holders that people have been asking for, for quite some time.
Should You Buy Them?
If you already own PACKOUT boxes or a fleet of M12 and M18 tools, these accessories are an easy yes. The drill-mounted bit holder solves a small but persistent annoyance, and the PACKOUT-compatible cases keep everything organized in one place.

If you are not invested in Milwaukee’s system yet, the PACKOUT platform is still the headline item: it is the best modular tool storage option out there, and the growing accessory catalog only makes it more compelling.
Conclusion
Neither release reinvents the workshop, but both make daily work smoother. The PACKOUT system remains the backbone worth building on, while the Shockwave bit holders are a cheap, thoughtful fix for a problem every cordless tool owner recognizes.
