The Festool 577477 D 3/16'' CE/W Brad Point Drill Bit is a 3/16 inch brad point drill bit built for clean, accurate hole drilling in wood and plastic. This is a brad point drill bit designed for drilling clean, accurate holes in wood and plastic. Model Number 577477. If you are using a Festool cordless drill with the CENTROTEC system, this bit gives you a compact, fast-changing setup that helps you drill with better control and less slop at the tip.

What makes this bit worth paying attention to is how it handles hole quality. The centering point helps the bit start where you want it instead of skating across the surface, and the cutting geometry is built for quick, clean bore holes. Festool also calls out rapid chip ejection, which matters more than it sounds like it should. Chips clear faster, the bit runs cooler, and you get less friction and heat build-up that can dull the edge early.

The CENTROTEC shank is a real advantage if you are already on the Festool platform. It is designed to improve force transfer between drill and bit, reduce the chance of slippage, and keep runout low. Festool also notes that the CENTROTEC setup cuts overall drill length by nearly 1-1/2 inches compared to a standard keyless chuck arrangement, which is a big help when you are working inside cabinets, between framing members, or in other tight spots where every bit of clearance matters.

Material and finish matter on small-diameter bits, and Festool backs this one with precision-ground steel for longer edge life and a corrosion-resistant finish to resist rust, pitch, and resin build-up. The bit is high-alloy steel. In practical terms, that means less time fighting a gummy bit in wood products and more consistent results across repeated holes.

On the job, this bit is a good fit for cabinet work, trim installs, punch-list drilling, and general shop use where clean entry and accurate placement matter more than brute-force boring speed. It is also suited for MDF, glued solid wood, laminated chipboard, and acrylic or plastic drilling. Because the shank can also be used in standard three-jaw chucks, you are not locked into one drill if you need to move between tools.

If you already own Festool CENTROTEC-compatible drills and want a small wood drilling bit that changes fast, tracks straight, and stays compact, this is the kind of accessory that makes the system feel worthwhile. It is not trying to be an all-material general-purpose bit. It is built for clean wood and plastic drilling, and that focus is exactly why it makes sense for finish carpenters, cabinet installers, woodworkers, and serious DIY users who care about hole quality.
