Key Features
Impact-Ready BitsThis Festool impact bit set uses extra impact-resistant 1 inch bits built for repeated fastening with an impact driver, not light-duty drill duty. Lockable HolderThe included 1/4 inch lockable bit holder speeds up bit swaps and keeps the bit secured, which matters when you are moving from screw type to screw type on the job. Useful Mix, Small CaseYou get five common driver profiles in a compact BitBOX with a belt clip holder, so the bits you actually use stay organized and close at hand.
Overview
The Festool 204384 5-Piece Impact Bit Set w/ Lockable Impact Bit Holder is a compact driver bit set for impact fastening. This is a driver bit set designed for screwdriving and fast bit changes with an impact driver. Model Number 204384. It is aimed at users who want the common bit styles they reach for most, packed into one small cassette instead of bouncing around loose in a tool bag.
What makes this set worth a look is that it is built around real impact-driver use, not general-purpose drill bits trying to do everything. Festool lists the assortment as extra impact-resistant, and each included bit is 1 inch long, which keeps the setup compact in tight cabinets, mechanical spaces, and punch-list work. The mix covers Phillips #2, Phillips #3, Torx T25, Torx T30, and Square Driver #2, so it hits the fasteners many contractors and installers see every day.
The included lockable 1/4 inch bit holder is the other half of the story. Instead of pulling bits in and out of a standard holder all day, the lockable design helps keep changes quick and secure. If you are moving between framing hardware, construction screws, cabinet screws, and general fastening tasks, that saves time in a way that is easy to appreciate after a long day. The belt-clip holder also gives you a simple way to keep the set on you instead of back in the box or van.
From a design standpoint, this is a straightforward kit done the right way. The BitBOX keeps the set organized and protected, and the short 1 inch bits make sense for impact driving because they stay compact and reduce the overall length of the tool and holder combination. That helps when you are working inside boxes, corners, or other spots where a longer bit setup just gets awkward.
Festool specifically positions this set for the TID 18 cordless impact screwdriver, but it is not limited to that tool. With its 1/4 inch interface, the set also makes sense for other impact drivers that accept standard 1/4 inch bits. That gives Festool TID 18 owners a purpose-built option while still making the kit useful for anyone already running a compatible impact driver platform.
Who should buy it? This set makes the most sense for contractors, installers, remodelers, and serious DIY users who want a small, grab-and-go impact bit assortment instead of a giant mixed set full of profiles they rarely touch. If your work is mostly fastening and you want a clean, compact kit with a proper lockable holder, the Festool 204384 5-Piece Impact Bit Set w/ Lockable Impact Bit Holder is the kind of simple accessory that earns its keep fast.

Keep the lockable holder loaded with the bit you use most and leave the rest in the BitBOX. With 1 inch bits, that gives you a shorter overall setup for tighter work and faster swaps when the screw type changes.
