The Festool 492524 Centrotec Countersink With Pilot Bit And Depth Stop is a 4.5 mm drill countersink made for drilling pilot holes and countersinking screw heads in one operation. This is a drill countersink designed for single-pass screw prep in finish work, cabinet work, furniture building, and general installation. Model Number 492524. If you want repeatable hole depth and cleaner visible fastener results without swapping between separate bits, this accessory is built for exactly that job.

What makes this countersink drill bit useful is the adjustable drilling and countersinking depth. Instead of drilling first and then switching tools to seat the screw head, you can handle both steps in one setup. That saves time on repetitive work and helps keep screw holes uniform across a run of parts. Festool also uses a free-spinning depth stop, which is there for a real reason: when the stop meets the work surface, it rotates freely to help avoid burning, scuffing, or leaving a ring on finished material.

The bit is sized at 3/16" (4.5 mm), and uses a pilot bit with a countersink body. Festool calls out a fully adjustable design with an exchangeable drill bit, so when the pilot wears out you do not have to replace the whole assembly. That matters if you use it regularly in production work or on install jobs where a countersink bit gets a lot of cycles. The long precision-milled hex shank is designed to cut down on wobble and runout, which helps the bit start cleaner and track more accurately.

On the tool side, this accessory is built around the Festool CENTROTEC interface. It is suitable for Festool cordless drills with the CENTROTEC system and for use in the WH-CE CENTROTEC tool chuck. Festool also states that the CENTROTEC shank can be used with standard or keyless chucks, but the main advantage is inside the CENTROTEC setup where you get fast bit changes, secure engagement, and a more compact overall drilling setup. That shorter, lighter configuration is a real benefit when you are moving through a long list of pilot holes and countersinks.

In practical use, this Festool drill countersink fits jobs where the finished surface matters. That includes furniture manufacture, kitchen fitting, installation work, and other visible screw fastening in wood, aluminum, acrylic, and mineral material. It is a good fit for woodworkers, trim carpenters, cabinet installers, and serious DIY users who want more control over screw seating depth and a cleaner finished look. If you already run Festool CENTROTEC drills, this is one of those accessories that makes the system make more sense the more often you use it.
