The Festool 577395 BKS SYS3 D3-8 K CE/W 18-Piece Centrotec Subby Brad Point Bit Cassette, 3mm-8mm is a compact drill bit and driver bit set built for organized drilling and fastening with Festool cordless drills. This is a bit set designed for wood drilling and screwdriving in shop, install, and finish work. Model number 577395. If you already run Festool's CENTROTEC setup, this kit gives you the everyday sizes in one lid-compartment cassette that stays easy to carry and easy to find.

What makes this set useful is the mix of bits. You get twelve driver bits for common screwdriving work plus six short spiral wood drill bits with a centering point for clean starts in wood-based materials. Festool calls out use in all types of wood, glued solid wood, MDF, and acrylic glass. In plain terms, that means this set covers a lot of the boring-and-fastening work that happens during cabinet installs, punch work, trim jobs, and general assembly.

The short brad point drill bits matter more than they sound on paper. A shorter bit gives you better control when you are drilling shelf-pin style holes in panels, boring in narrow spaces, or working inside cabinets where a standard-length bit gets awkward fast. Festool also notes the bits have a center point and two cutters, which helps them start accurately and cut clean holes. The two chamfers are there for longer service life, including work in laminated chipboard where edge wear can show up quickly on cheaper wood bits.

The bit construction is another real advantage. The wood drill bits are made from high-alloyed ball bearing steel, which speaks to durability and edge retention in repeated shop use. That matters if this set is going to live in a drill every day instead of sitting in a drawer. The integrated magnets in the cassette hold bits and drill bits securely, so you are not chasing loose pieces around a case or dumping the whole set just to get one size.

Storage is a big part of why someone buys this over a generic bit set. The cassette is made to fit Systainer3 models with lid compartments, and the bit modules can be flexibly moved. That gives you a cleaner workflow if you already organize your gear in the Festool system. It can also be used as a separate box, so it still makes sense even if you are not dropping it into a Systainer every day.

On compatibility, this set is intended for Festool cordless drills with the CENTROTEC interface and for use in the WH-CE CENTROTEC tool chuck. ACME also lists compatibility with Festool cordless drills and cordless percussion drills with FastFix tool reception and the WH-CE CENTROTEC chuck. The practical takeaway is simple: this is not just a loose collection of bits, it is meant to work cleanly inside the Festool drilling system for faster changes and a more compact setup.

If you are a cabinet installer, finish carpenter, remodeler, or serious DIY user already invested in Festool drilling tools, this set makes a lot of sense. It is especially strong for wood-based sheet goods, jobsite organization, and tight-space drilling where short brad point bits are easier to manage. If you do not use the Festool CENTROTEC platform, you may not get the full value out of what this cassette is built to do.
