Festool 578110 Forstner Drill Bit Set SYS3 S 76-FB CE-SORT/5 is a wood-boring bit set for clean, accurate hole drilling in softwood and hardwood. This is a Forstner drill bit set designed for creating blind holes, counterbore holes, through-holes, and angled holes in woodworking and carpentry applications. Model Number: 578110. If you need one organized set that covers the common larger hole sizes without digging through loose bits, this one is built for that job.

The set includes five Forstner drill bits in 15 mm, 20 mm, 25 mm, 30 mm, and 35 mm sizes, plus a 4 mm centering bit and a punch. That gives you a useful spread for furniture work, carpentry, wood construction, assembly work, and detail jobs like installing a peephole. In practical use, that means you can handle clean flat-bottom holes, neat counterbores, and larger-diameter boring without jumping between mismatched accessories.

What matters here is not just the size range, but how the set is built. Festool calls out replaceable centering points, which is a real advantage if you do repetitive drilling and want to keep the bits tracking properly over time. The bits are made from high-quality ball bearing steel and can be resharpened up to five times, so this is not a throwaway set. For a pro shop or serious woodworker, that longer service life matters because large specialty bits take abuse fast when used regularly.

The included 4 mm centering bit with conical shaft expands what the set can do. Festool specifies it for through-holes and angled holes, with splinter-free drilling on both sides at angles up to 45 degrees. That is useful when clean entry and exit matter, especially in visible workpieces, cabinetry parts, furniture components, and finish carpentry where breakout can ruin the part.

On the tool side, these bits are designed to insert directly into the Festool CENTROTEC tool chuck and lock in place. That makes this set a much better fit for users already working with Festool cordless drills using the CENTROTEC interface, because setup is quicker and the bits integrate into the system the way they were meant to. Festool also ties the storage side into its Systainer3 ecosystem, and this compact Systainer3 S case is suitable for the Systainer3 Rack if you want the accessory set to live in a larger shop or mobile storage setup.

The case itself is part of the appeal. Instead of loose large-diameter bits rolling around in a drawer, everything is stored in a compact 10.43 inch x 6.73 inch x 2.79 inch Systainer3 S with dedicated spots for the accessories. That keeps the cutting edges protected and makes it easier to see what is missing before you leave for a job. For anyone who already runs a Festool workflow, that organization piece is not a small thing.

Who should buy it? This set makes the most sense for carpenters, cabinet installers, furniture makers, remodelers, and serious DIY users who want accurate larger-diameter wood drilling and already use Festool's CENTROTEC setup. If you just need an occasional large hole in rough lumber, a cheaper bit might get by. If you care about clean results, repeatability, service life, and organized storage, this set is aimed squarely at you.
