The device shown in TWsOriginal’s TikTok video is the Milwaukee Shockwave Impact Duty Right Angle Drill Adapter. As the name implies, the purpose of this device is to extend and bend your Milwaukee drill or impact driver’s drill bit into a 90-degree angle, allowing you to drive in fasteners even when the full device won’t fit into a gap.

It’s a remarkably simple device: The back tip of it has a metal adapter with the same fitting as a drill bit, allowing you to stick it into the chuck on your driver. Through a hardened internal mechanism, the rotational power from your driver is transferred through the adapter and into the adapter’s own drill bit, giving you just as much torque as you’d normally get with the driver by itself.
The inside of the device also features Milwaukee’s proprietary Shockzone technology, which absorbs the brunt of the torque from the driver. Not only does this help to keep the power focused into the adapter’s bit, it also helps to preserve the adapter’s overall structural integrity. It certainly helps that the adapter is made of Custom ALLOY76 steel, so it can endure quite a bit of punishment.
