Key Features
Overview
The Festool 577780 12-Piece Driver Bit Cassette BKS SYS3 50mm CE F is a compact driver bit set built for Festool cordless drills with the CENTROTEC interface. This is a driver bit cassette designed for organized screwdriving and installation work. Model number 577780. If you already run Festool drilling and fastening tools, this set gives you the common bit profiles you need in a cassette that stores cleanly inside Systainer3 lid compartments or works as a separate box on its own.
What makes this set more useful than a loose handful of bits is the way Festool packaged it. The 50 mm bit length gives you more reach than short insert bits, which helps when you’re working around cabinet hardware, inside carcasses, near trim, or anywhere a little extra clearance matters. Festool also notes that the extension from the WH-CE CENTROTEC chuck is about 22 mm, which helps keep the setup compact while still giving you practical access to recessed fasteners.
The included selection is aimed at real installation work, not filler sizes you will never touch. You get Phillips, Pozidriv, square, and Torx profiles that cover furniture assembly, kitchen fitting, cabinet installation, doors, windows, wood substructures, and general fastening in wood, metal, and plastic. That makes this a smart fit for installers, finish carpenters, cabinet crews, remodelers, and anyone who spends more time driving screws than drilling holes.
Festool calls out two details that matter for longevity. First, the bit tips are chemically nickel-plated for longer service life. Second, the bits have a chrome coating for improved corrosion protection. That is the kind of thing that actually matters if your tools live in a van, trailer, or job box instead of a climate-controlled shop. Better protection means the bits are less likely to get rough, stained, or neglected after repeated use.
The storage side is a big part of the value here. The cassette fits neatly into Systainer3 models with lid compartments, so it becomes part of a cleaner system instead of another loose accessory. Bits are held in modules that can be flexibly moved, which is useful if you want to group your most-used drive types together. For guys who care about workflow, that means faster setup and fewer interruptions when you are bouncing between different screw types on the same job.
Compatibility is straightforward and important. This set is intended for Festool cordless drills with the CENTROTEC interface and is used in the WH-CE CENTROTEC tool chuck. If that is your setup, this cassette makes sense. If you are not on the CENTROTEC system, the value shifts more toward the storage and bit assortment than the full quick-change advantage.
Who should buy it? If you use Festool drills for cabinet installs, furniture assembly, punch-list work, trim installs, or general jobsite fastening, this is the kind of organized bit set that earns its keep fast. It is not trying to be every bit you will ever own. It is a focused, job-friendly fastening set that stores well, travels well, and covers the screw types you hit all the time.
Organized Fastening That Travels Well
This set makes more sense the minute you have to move from one room to the next. Instead of loose bits in a pocket or buried at the bottom of a case, the cassette rides as part of the Systainer system and stays ready for the next task.
- Designed to fit Systainer3 models with lid compartments
- Can also be used as a separate box when you do not need the full system
Reach the Fasteners You Actually Fight With
The 50 mm format is a practical middle ground. You get more reach and visibility than short insert bits without turning your drill into a clumsy setup for finish and installation work.
- Bit length: 50 mm, or about 1-15/16 in.
- Approximate extension from the WH-CE CENTROTEC chuck: 22 mm, or about 7/8 in.
Built Around the Festool System
If you already organize your gear in Systainers, this cassette feels like it belongs there. That matters because small accessories are usually the first things to get messy, misplaced, or replaced too early.
- Flexible bit modules help you arrange the set for your workflow
- Made for Festool cordless drills with CENTROTEC interface compatibility
Common Profiles, Not Throwaway Fillers
This is a focused installation set. The mix covers the screw types you are likely to hit in cabinetry, hardware, trim, and general fastening instead of padding the count with oddball sizes.

Pro Tip
If you use the same three or four bits every day, move those modules to the easiest-to-grab position in the cassette before it goes into your Systainer lid. That small setup step saves more time on install days than you would think.
