The Festool 499806 Straight Edge Trimming Bit HW D19/12, 8mm Shank is a carbide edge trimming router bit built for flush trimming laminate, edge banding, and similar sheet goods. This is a router bit designed for edge trimming and flush-trim work. Model Number 499806. If you are running a compatible Festool router and need a clean, guided trim cut along finished edges, this bit is built for that job.

The big advantage here is the bearing-guided flush-trim setup. The ball bearing follows the edge while the cutter removes the overhang, which helps keep the cut controlled and consistent. Festool rates the cutter at 19 mm diameter with a 12 mm cutting length, so it is sized for precise trimming work rather than heavy bulk removal. That makes it a strong fit for edge banding, laminate overhang, and finish-sensitive trim applications where control matters more than brute force.

Festool also gives this bit a replaceable 12 x 12 mm reversible carbide blade. In real use, that matters because you are not throwing away the whole cutter body once an edge goes dull. The blade can be indexed and used four times, which is a practical feature for shops and installers doing repeat trimming work. Carbide also holds up better than basic steel when you are working on abrasive laminates and manufactured panels.

The 8 mm shank is another important detail. On a router bit like this, shank strength affects stability and cut quality. A robust 8 mm shank helps the bit run with better support in compatible routers, which is especially useful when you are working close to finished surfaces and cannot afford chatter or a wandering cut. Festool lists this cutter for use with the OF 1010, OF 1010 R, and MFK 700, making it a straightforward choice for users already on that platform.

This bit is a good fit for cabinet installers, finish carpenters, millwork shops, and serious woodworkers trimming edge banding or laminate cleanly and repeatably. It is not the bit you buy for general routing. It is the one you buy when you need a dedicated flush-trim cutter that tracks the work reliably, leaves a clean edge, and gives you a replaceable cutting edge instead of making you replace the entire bit every time it dulls.
