The Festool 485332 HL 850 HSS Replacement Blade for Undulating Cutterhead is a replacement planer blade made for Festool rustic texturing applications. This is a planer replacement blade designed for creating a scalloped, hand-hewn effect in solid wood. Model Number: 485332. If you use an HL 850 setup to add texture and character instead of a flat finished surface, this is the blade that keeps that cutterhead working the way it should.

What matters here is not just that it is a replacement part, but what kind of cut it is meant to produce. This blade is built for the undulating rustic planer head, part number 485331, and is intended to create a wavy, distressed surface that looks more like hand-worked timber than machine-planed stock. That makes it useful for furniture makers, finish carpenters, remodelers, and woodworkers who want visible texture in beams, trim, mantels, and other exposed wood details.

Festool describes the cutting action as a spiral slicing cut, similar to the way a skewed hand plane meets the wood. In practical terms, that means the blade engages the material more cleanly than a straight scraping action. The benefit is less chatter and a smoother overall texture, which is important when you are trying to create a deliberate rustic surface instead of a rough result that looks accidental.

The self-aligning blade design is another real-world advantage. Blade changes do not turn into a long setup job. You loosen three screws, replace the blade, and tighten it back down. On the bench or on site, that matters because specialty accessories are only useful if they are quick enough to swap in when the job calls for them.

This Festool planer accessory is intended for the planer head HK 82 RW and is listed as compatible with the Festool HL 850 planer when using the proper rustic cutterhead setup. It is specifically noted as not suitable for HLC 82, so compatibility matters here. If you are buying a replacement, match the blade to the correct head before ordering.

Build-wise, this is a precision-ground HSS spiral blade made for repeatable results over a long service life. It is a small part, but it has a direct effect on surface quality, consistency, and the look of the finished work. If your current blade is worn, chipped, or no longer leaving an even rustic pattern, replacing it is the difference between a controlled decorative finish and a surface that needs cleanup.

Who should buy it? Anyone already running a Festool HL 850 with the undulating rustic head and wanting to maintain that specific textured finish. If you are after standard smoothing and flattening, this is not the blade for that job. If you want decorative wood texturing with less chatter and quick replacement, this is the right accessory to keep on hand.

A small part that makes a very specific finish possible
