The Festool 577782 6-Piece Driver Bit Cassette BKS SYS3 100mm CE F is a driver bit cassette built for organized fastening work with Festool cordless drills. This is a driver bit set designed for screwdriving in wood, metal, and plastic. Model Number 577782. If you already run the Festool CENTROTEC system, this set gives you long 100 mm bits in a compact cassette that stores cleanly and is ready for cabinet installs, door hardware, window work, and general jobsite fastening.

What makes this set useful is not just the bit count, but the format. Each bit is 100 mm long, which gives you better reach into hardware pockets, behind obstructions, and inside assembled casework. That extra length is helpful in furniture assembly, kitchen installation, and fitting work where a stubby bit can leave the drill body rubbing against finished surfaces or hardware.

The cassette itself is set up to keep the bits securely held in modules, so you are not digging through a loose pile every time you need a different tip. For installers and finish crews, that saves time and keeps the right bit close at hand. Festool also designed the cassette to fit Systainer3 models with lid compartments, which matters if you are already organizing your drill, hardware, and accessories inside the same storage system.

Festool positions this set around CENTROTEC compatibility, and that is the key buying point. It is suitable for Festool cordless drills with the CENTROTEC interface for use in the WH-CE CENTROTEC tool chuck. If that is your platform, this cassette drops into the workflow without adapters, mix-and-match guesswork, or odd storage compromises.

Bit life also gets attention here. Festool notes a chemically nickel-plated bit tip for longer service life, while supplementary retailer data also calls out chrome coating for improved corrosion protection. In plain terms, that means these bits are built to hold up better when they live in a van, shop, or job box instead of a drawer that never gets opened.

This set is a smart fit for cabinet installers, finish carpenters, remodelers, and anyone doing repeated fastening in built-ins, doors, windows, pergolas, fences, carports, and other wood construction. It is not trying to be a giant all-in-one assortment. It is a focused Festool driver bit cassette for users who want long-reach driver bits, clean storage, and direct compatibility with the CENTROTEC system.
