The Festool HW 45°-OFK 500 Chamfer Cutter is a router bit accessory made for edge chamfering with compatible Festool edge routers. This is a chamfer cutter designed for cutting 45 degree chamfers on plastic edging, solid wood edging, solid wood panels, and frames. Model Number 490090. If your job is breaking sharp edges and leaving a clean, uniform bevel, this cutter is the right profile for it.

What makes this bit useful is not just the profile, but how directly it is aimed at common edge-finishing work. Festool lists it for chamfer milling plastic or solid wood edging, plus chamfering solid wood panels and frames. In practical terms, that means it is a good fit when you are finishing visible edges on casework parts, panel work, trim components, or frame stock where consistency matters more than improvising with a general-purpose bit.

The cutter uses carbide blades for long service life. That matters because edge work often means repeated passes across similar material, and a durable cutting edge helps keep the profile consistent over time. Festool also notes easy cutter replacement with a screw and quick depth adjustment. On the bench or on site, that means less downtime when you need to reset the cut or swap the cutter during ongoing work.

The 27.00 mm diameter and 45.00 degree cutting angle define exactly what this accessory is built to do. It is not a multipurpose shaping bit. It is a dedicated chamfer cutter for users who want a predictable bevel profile and want to keep their edge router setup straightforward. Festool also specifies that this version is supplied without a bearing ball, which is important if you are matching it to the intended machine setup rather than expecting a bearing-guided trim bit.

Compatibility is clear: this cutter is sized for the Festool OFK 500 and Festool OFKC 500. That makes it a platform-specific accessory rather than a universal router bit claim. If you already run one of those machines, the fit and intended use are straightforward. If you do not, this is not the bit to buy based on profile alone.

Who should buy it? Woodworkers, finish carpenters, cabinet installers, and shop users doing repeat edge finishing on wood or plastic edging will get the most value here. If you need a dedicated Festool chamfer cutter for fast, repeatable edge breaks on compatible OFK 500 or OFKC 500 routers, this bit makes sense. If you need a broader range of profiles or a universal fit, you should look elsewhere.
