The Festool 498974 Centrotec Impact Bit Holder BH 2-3/8" (60 mm) is a magnetic bit holder built for Festool cordless drills with the CENTROTEC interface. This is a bit holder designed for driving screws with standard insert bits while keeping the speed and secure fit of the Festool quick-change system. Model Number 498974. If you already run CENTROTEC, this adapter matters because it lets you use everyday 1/4 inch-style driver bits without giving up the compact feel and fast bit changes that make the system useful in the first place.

The big advantage here is straightforward: it adapts standard bits to the CENTROTEC chuck. That means less fumbling with separate chucks and fewer interruptions when you're moving from one fastener type to another. Festool also gives this holder a magnetic insert to keep bits from backing out and getting lost, which is a small feature until you are working overhead, inside a cabinet, or up on a ladder.

At 2-3/8" (60 mm) long, the holder gives you extra access into spots that are hard to reach with shorter holders. That added reach is useful for hardware installs, finish work, assembly, and general fastening where the body of the drill cannot sit right on top of the screw. Festool pairs that reach with a long, precision milled hex shank that helps reduce wobble during use. In practical terms, that means steadier bit engagement and less chance of cam-out on screw heads.

This holder is also built with a thicker, stronger sidewall for longer life and for use with impact or standard bits. That is worth paying attention to if your work bounces between a drill driver and tougher fastening tasks where the holder takes more abuse. It is not just about surviving the job, but about holding its shape and keeping bit fit consistent over time.

On the system side, this holder is made for Festool cordless drills with the CENTROTEC interface and for use in the WH-CE CENTROTEC tool chuck. The CENTROTEC shank is also designed to work in standard or keyless chucks, which gives you some flexibility if your setup changes from tool to tool. One clear limitation: it is listed as not suitable for the Festool TID 18, so buyers using that impact driver should not treat this as a fit.

Who should buy it? Anyone already invested in Festool drilling and screwdriving who wants to run standard bits without giving up the CENTROTEC workflow. It makes the most sense for cabinet installers, finish carpenters, service techs, punch-list work, and serious DIY users who care about compact setup, quick changes, and cleaner bit control more than just getting by with a generic holder.
