HL 850 HSS Replacement Blade is a Festool planer blade designed for the Undulating Rustic planer head 485331 to create a scalloped, hand-hewn effect in solid wood. The undulating rustic profile shapes the surface so each pass leaves a distinctive carved texture that highlights grain. The spiral cutter engages material with a slicing action, similar to a skewed angle hand plane, so the planer contacts the wood progressively instead of all at once, which reduces chatter during the cut. That same slicing engagement refines the cut surface, so the scalloped texture stays pronounced without torn fibers. The blade is made from durable, precision ground HSS, so the cutting edges maintain their geometry over a long service life, supporting consistent texturing from job to job.
This Festool HL 850 HSS Replacement Blade uses a self-aligning design, so the blade seats itself in the Undulating Rustic planer head without manual fine positioning. The change process is described as loosening three screws, replacing the blade, and re-tightening the screws, so the steps are straightforward and repeatable. That simple sequence keeps blade swaps from interrupting production for long and brings the cutterhead back into service quickly. Because alignment is built into the blade interface, the rustic undulating profile returns to its intended position after each change, which helps preserve the scalloped pattern from one blade to the next on matching workpieces.
The HL 850 HSS Replacement Blade for the Undulating Rustic planer head 485331 is intended for creating texture directly in solid wood, so it fits naturally into jobs where a carved, scalloped face is part of the design. The blade forms a scalloped, hand-hewn effect, so it is suited to surfaces where a visible tool-mark aesthetic is desired instead of a flat, planed finish. Because the spiral cutter engages the material with a slicing action, similar to a skewed angle hand plane, the cut is controlled enough to shape full-length boards while maintaining the rustic pattern across the grain. That slicing action reduces chatter as it enters and exits the cut, so long passes over solid stock can stay consistent in depth and rhythm. The undulating rustic design works with the cutterhead to structure a repeating wave pattern, so each pass adds a predictable visual cadence to beams, rails, or panels.
The blade is described as a durable, precision ground HSS spiral-cutting blade, so each cutting edge is formed to tight tolerances and backed by high speed steel. That combination keeps the edge geometry stable over a long service life, so the scalloped pattern stays similar from the first project through many subsequent runs. The spiral-cutting layout engages the work with a slicing motion, so each edge meets fibers at an angle and reduces tearing as the blade crosses the grain, which supports a smoother underlying surface beneath the sculpted waves. The self-aligning blade design means that when the three screws are loosened, the blade replaced, and the screws re-tightened, the edge returns to its intended position without additional setting work, so the depth and spacing of the profile remains consistent across blade changes. The HSS rustic undulating format ties the material, profile, and mounting together, so the planer head delivers the same carved appearance each time it is put back into service.
The HL 850 HSS Replacement Blade is made for the Festool Undulating Rustic planer head 485331, so the profile and mounting match that specific cutterhead.
The blade creates a scalloped, hand-hewn effect in solid wood, so each pass leaves a carved texture instead of a flat planed surface.
The spiral-cutting blade engages the material with a slicing action, similar to a skewed angle hand plane, so it reduces chatter and produces a smoother textured cut.
The blade is made from durable, precision ground HSS, so the cutting edges resist wear and preserve the profile over a long service life.
The blade uses a self-aligning design, so you loosen three screws, replace the blade, and re-tighten the screws, returning the cutterhead quickly to working condition.
The self-aligning blade seats in the same position each time, so the rustic undulating scallop pattern stays consistent across multiple blade changes.
The HL 850 HSS Replacement Blade for the Undulating Rustic planer head 485331 is focused on creating a scalloped, hand-hewn effect in solid wood using a spiral-cutting, self-aligning design. The durable, precision ground HSS construction supports a long service life while maintaining the undulating profile that defines the texture. For work that relies on a repeatable rustic pattern and reduced chatter from a slicing action similar to a skewed angle hand plane, this Festool planer blade provides a purpose-built option for the specified cutterhead.
