Stop double-checking your marks. The HONGDUI HD38 serves as a high-efficiency layout powerhouse that eliminates the guesswork from your bench work. By locking its heavy-duty T-style shoulder flush against your workpiece, the integrated micro-hole guide allows your mechanical pencil to glide effortlessly for seamless, parallel lines. Whether layout out mortise-and-tenon joints or breaking down sheet goods, the HD38 slashes your layout time while doubling your precision.
Système "Line Master" de haute précision : Dispose d'un bloc coulissant de précision qui se verrouille solidement en place, permettant un traçage parallèle sans faille et un marquage répétable le long de la longueur de la pièce à travailler.
Design modulaire 2-en-1 : La poignée en T peut être détachée, permettant à l'outil de se transformer d'un équerre professionnelle en un bord droit de haute précision autonome.
Référence parfaite à 90° : La poignée est usinée CNC pour garantir une référence à 90 degrés parfaitement d'équerre par rapport au bord de votre planche, éliminant l'inexactitude des règles traditionnelles estampées.
Dessin de cercles et d'arcs : Le bloc coulissant comprend un point de pivot dédié, permettant à la règle de fonctionner comme un compas à grande échelle pour dessiner des cercles et des arcs précis.
Disponible en plusieurs longueurs : La série HD38 est proposée en différentes tailles, généralement comprises entre 200 mm et 800 mm (8" à 32"), pour convenir à tout, des petits composants de mobilier aux grands panneaux.
Mécanisme de verrouillage anti-glissement : L'écrou de verrouillage en laiton moleté offre une prise sécurisée, sans outil, sur le bloc coulissant, garantissant qu'il ne se déplace pas pendant le marquage.

FAQ
Check out the most common questions our customers asked.
What is the difference between the HD38 and the HD38V?
HD38 (Standard): Features a fixed 90-degree aluminum handle. It is designed for rock-solid right-angle layouts and parallel scribing.
HD38V (Adjustable): Features a rotating handle that allows for precision 0-90° angling. It includes a knurled brass knob for positive, drift-free locking at any angle, essentially acting as a high-precision protractor and T-square in one.
What is Hadfield Steel and why is it used for the ruler body?
Hadfield steel (manganese steel) is used for its superior toughness and shock resistance compared to standard spring steel. It has a hardness of approximately HRC 50 and is finished with a Titanium coating for extreme wear resistance, ensuring the ruler doesn't lose its straightness or surface quality over time.
What sizes are available?
The HD38 series is available in multiple lengths:
Metric: 200mm, 400mm, 600mm, and 800mm.
Imperial: 8 Inches, 16 Inches, 24 Inches, and 32 Inches.
What is the purpose of the Line Master sliders?
The Line Master is a modular sliding block that sits on the ruler. It allows for:
Repeatable Marking: Lock the slider at a specific measurement to mark the same distance on multiple workpieces.
Parallel Scribing: Press the slider against the edge of your board and slide the ruler to draw a perfectly parallel line.
Compass/Circle Drawing: The sliders can be used as pivot points for drawing large arcs and circles.
Why are there different colored sliders (Blue/Orange)?
Different colored sliders are often included in longer sets (600mm+) to help woodworkers distinguish between different presets or stops when performing complex layout tasks that require multiple measurements.
How accurate are the markings?
The HD38 features dual-scale laser-etched markings on both the front and back of the blade. This allows for clear readability even in awkward positions. The markings are mathematically aligned with the CNC-machined handle to ensure a perfect 90° reference.
Is the ruler handle removable?
Yes. The handle can be detached, allowing the Hadfield steel ruler to be used as a standalone straight edge or for layout tasks where the T-head would be in the way.
How do I calibrate the HD38V angle?
For the adjustable HD38V, you can use the laser-etched degree scale on the handle assembly. For critical accuracy, it is recommended to verify the 0° (90° to the handle) and 45° settings with a high-precision engineer's square during your initial setup.
Does the titanium coating protect against rust?
Yes, the titanium coating is highly resistant to corrosion. However, it is still best practice to wipe the ruler down with a dry cloth after use. If you work in a high-humidity environment, a light application of camellia oil or a dry wax will provide extra protection for the exposed steel edges.
How do I clean the Line Master sliders?
If the sliders become gritty or difficult to move, it is likely due to fine sawdust trapped in the track. Remove the slider, blow out the track with compressed air, and wipe the ruler's edge with a bit of denatured alcohol. Avoid using oil on the ruler body, as it will attract more dust.
