HONGDUI HD39 Pialla per scanalature
Regolazione di precisione della profondità: Dotata di un meccanismo di regolazione a passo fine che consente un controllo della profondità sub-millimetrico, garantendo fondi perfettamente piatti e consistenti nelle giunzioni.
Montaggio della lama a doppio orientamento: La lama può essere montata in posizione standard per lavori generici o in posizione "bullnose" per raggiungere angoli stretti o scanalature chiuse.
Acciaio della lama superiore: Dotata di una lama in acciaio per utensili ad alto tenore di carbonio (HRC 58-60) che arriva affilata di fabbrica e mantiene un taglio netto anche su legni duri e densi.
Guida integrata per l'affilatura della lama: Molte versioni includono una dima o un supporto dedicati per l'affilatura, garantendo la possibilità di mantenere facilmente il corretto angolo del bisello secondario.
Manopole ergonomiche: Grandi manopole di regolazione e bloccaggio zigrinate offrono una presa confortevole e un'elevata leva per modifiche sicure e senza attrezzi.
Stabilità del gambo quadrato: La lama utilizza un design a gambo quadrato, che previene la torsione laterale o il "vibrato" durante tagli pesanti, a differenza dei tradizionali pialletti a gambo tondo.
Suola pressofusa o lavorata a macchina: Dotata di una suola ampia e rettificata di precisione che fornisce una superficie di riferimento ampia, garantendo che l'utensile rimanga stabile e piatto durante il taglio.

About HD39
Master the Depth: HD39 Router Plane
The HONGDUI HD39 is a professional-grade router plane engineered to bring unparalleled accuracy, control, and repeatability to your joinery work. The tool eliminates the guesswork when cleaning up dadoes, routing hinges, or cutting perfect tenons.
Featuring a hyper-accurate depth adjustment mechanism, the HD39 allows for micro-adjustments within seconds, giving you absolute control over every shaving. Whether you are leveling a deep housing joint or perfecting a delicate inlay recess, its low center of gravity and rigid stability provide the smooth gliding action required to achieve a flawless, flat-bottomed finish every time.

FAQ
Check out the most common questions our customers asked.
What makes the HD39 different from traditional router planes?
Traditional router planes usually have a fixed blade orientation pointing directly forward or backward. The HD39 features three distinct mounting locations on the base and allows the blade mechanism to rotate 360° across four rotational directions. This modular design gives you total flexibility to navigate awkward corners, tight dadoes, and irregular grain patterns while keeping the wide sole flat on the workpiece.
Does it have an adjustable handle layout?
Yes. To accommodate different grip preferences and various mounting orientations of the blade, the handle positions on the HD39 are fully adjustable. This allows you to maintain optimal balance, downward pressure, and mechanical leverage regardless of how the plane is configured.
What is "Grain-Adaptive Cutting" and how do I use it?
When cleaning the bottom of a groove, changing grain directions can cause wood to tear out. Because the entire blade housing on the HD39 rotates 360°, you can change the angle of your approach on the fly. This lets you always cut with the grain rather than forcing the tool against it, resulting in a significantly cleaner surface finish.
What types of blades are included in the package?
The HD39 typically ships with two premium cutters:
- A 12mm Square Blade for flattening standard dadoes, grooves, and rabbets.
- A Spearpoint Blade designed specifically for reaching tight, hard-to-access corners and intricate inlay work.
Can I use blades from other brands (like Veritas or Lie-Nielsen) in the HD39?
No. Due to the unique 360° rotating modular mounting assembly, the HD39 uses a proprietary shaft geometry. Third-party replacement blades will not fit the mounting configuration.
How easy is it to remove the blade for sharpening?
Very straightforward. Unlike vintage tools where you must fiddle with the entire height-adjustment post, the cutters on modern HONGDUI planes separate efficiently. You can easily detach the cutting head from the shaft assembly, making it far simpler to lock into a honing guide (like the HONGDUI HD29) to achieve a razor-sharp edge.
How precise is the depth adjustment mechanism?
The HD39 utilizes a machined stainless steel lead screw paired with a knurled thumbwheel precision adjustment mechanism. It operates smoothly, allowing you to easily dial in micro-shavings measured in fractions of a millimeter for absolute depth control.
Does the height adjustment suffer from backlash or "slop"?
HONGDUI prioritizes low-backlash engineering across their entire joinery line. The thumbwheel and guide-post tolerances are machined tightly to virtually eliminate the annoying "dead zones" common in older threaded-post designs, meaning the blade responds almost instantly when you reverse direction.
Is the edge-guiding fence included with the base tool?
Please check the specific listing when purchasing. In many global e-commerce listings, the adjustable edge fence is sold as a standalone module or bundled as an upgraded kit variant. If you frequently route grooves parallel to a straight or curved edge, it is highly recommended to select the option that explicitly includes the fence assembly.
