Overview
The Festool Systainer3 SYS3 DF M 187, Model 577347, is a modular storage case with a built-in lid compartment for small parts and accessories. This is a tool storage organizer designed for keeping bits, drill bits, saw blades, screws, and other jobsite essentials sorted, protected, and close at hand. If you already work out of a Festool stack or just want a cleaner way to carry mixed hardware and accessories, this setup makes a lot of sense.
What sets this Systainer apart is the transparent lid compartment. Instead of burying small accessories underneath larger tools, it puts the stuff you reach for constantly right on top where you can see it fast. The adjustable partitions let you divide the lid compartment based on what you actually carry, whether that is long drill bits, assorted fasteners, driver bits, anchors, or small hardware. Festool also notes that compatible BKS SYS3 bit cassettes and drill bit cases fit the lid compartment, which gives you another way to keep the top organized without improvising.
The main body still gives you the standard Systainer3 M footprint, with internal dimensions of 15.31 x 10.83 x 5.75 inches and a total volume of 4.20 gallons. That means you are not giving up the core storage space just to gain the lid organizer. Festool specifically calls out that the internal dimensions match Systainer3 M models, so existing inlays can be used. That is a practical detail if you already have inserts or want this case to slot into an existing storage plan without starting over.
On the job, portability matters just as much as storage. This case weighs 4.19 pounds empty, carries a 44.09-pound load capacity, and supports 88.18 pounds when connected in a stack. Lid load is rated at 220.46 pounds. Those numbers matter because a storage box is only useful if it can actually move with the rest of your gear and hold up to real use. The Systainer3 platform is built for transport, stacking, and integration with Festool transport systems and mobile dust extractors, so it is not just a shop shelf organizer.
Compatibility is a big part of the appeal here. Festool states that this Systainer with lid compartment is compatible with the entire Festool Systainer system and can connect to different generations. It is also compatible with transport systems and mobile dust extractors. One thing worth knowing: the lid compartment works with BKS SYS3 bit cassettes and drill bit cases, but it is not suitable for Systainer T-LOC bit cassettes and drill bit cases. That is the kind of detail that saves you from ordering the wrong accessory.
This storage case is a good fit for carpenters, installers, cabinet crews, electricians, service techs, and serious DIY users who carry a mix of drill bits, screws, anchors, and small accessories from job to job. It is especially useful if you hate loose hardware rolling around in a bin or if you need one case that can hold both small consumables up top and larger tools or supplies below. If your workflow depends on fast access and clean organization, the Festool Systainer3 SYS3 DF M 187 does exactly what it is supposed to do without wasting space.
Keep Small Parts Visible and Sorted
The big win here is simple: you can see the small stuff without opening the main box and digging. For anyone doing repetitive drilling or fastening, that saves time all day.
- Transparent lid compartment gives a quick view of stored accessories
- Designed for bits, drill bits, saw blades, and other small parts
Set It Up Your Way
Fixed storage is fine until your kit changes. The adjustable partitions let this storage organizer adapt to the fasteners and accessories you actually use instead of forcing everything into one layout.

- Compatible with BKS SYS3 bit cassettes and drill bit cases
Built to Travel with the Rest of Your System
A storage box only earns its keep if it moves easily from shop to van to jobsite. This Systainer is made to connect with the broader Festool storage and transport setup, so it works as part of a system instead of as a one-off case.
- Compatible with the entire Festool Systainer system
- Works with transport systems and mobile dust extractors

The layout is practical for mixed kits. Small accessories stay separated in the lid while the main compartment stays open for tools, inserts, or larger supplies.
