In precision woodworking, clearing a groove or leveling a tenon cheek requires more than just a sharp edge—it requires absolute depth control. Following the success of the original KM17, the HONGDUI KM17 Pro has emerged as a flagship hand tool, blending heavy-duty "die steel" construction with the micrometric precision that has defined HONGDUI's reputation in the CNC era.
If you are looking for a tool that balances traditional hand-tool woodworking with modern industrial engineering, the KM17 Pro is designed for your bench.
1. The Engineering of Accuracy
While many router planes rely on simple friction locks, the KM17 Pro utilizes a micrometric cutting depth adjustment system.
Zeroing and Calibration: The "0" setting allows you to calibrate the blade height perfectly to the base, ensuring that your first pass is exactly where you intend it to be.
Die Steel Body: Unlike cast iron alternatives, the die steel body offers superior stability and a "mechanical beauty" that matches the aesthetic of HONGDUI's other high-precision instruments like the HD-MG21.
Depth Stops: The integrated depth stop allows for consistent grooves across multiple workpieces, a critical feature for professional-grade joinery.
2. Versatility in the Cut
The KM17 Pro isn't just for cleaning up dados. Its design accommodates a variety of complex joinery tasks:
Dual Blade Widths: The pro version typically includes interchangeable blades (often 1/4" and 1/2" or metric equivalents) for fine-tuning different groove sizes.
Adjustable Fence with CAM Lock: The fence is a standout feature, providing a stable guide for grooving along an edge. The CAM lock ensures that once your width is set, it stays set.
Removable Fence for Recesses: When you need to clean up a "blind" recess or a bow-tie inlay, the fence can be removed to give you full visibility and mobility.
3. Refined Ergonomics
HONGDUI's focus on reducing "hand fatigue" is evident in the KM17 Pro’s handle design. The wooden knobs are positioned to provide a low center of gravity, which prevents the plane from "tipping" during a heavy cut—a common issue with top-heavy router planes.
4. Technical Specifications for the Professional Shop
For woodworkers who track their shop's mechanical tolerances:
Body Material: Die Steel for maximum rigidity.
Adjustment Precision: Micrometric dial for sub-millimeter depth control.
Blade Compatibility: Supports a range of imperial and metric blades.
Visual Style: High-contrast, industrial finish that fits the modern "mechanical" workshop aesthetic.
Final Verdict
The HONGDUI KM17 Pro represents a bridge between heritage hand tools and modern manufacturing. Whether you are a fan of technical reviewers or a professional craftsman requiring 0.02mm-level control in your joinery, the KM17 Pro delivers a level of workmanship that is rarely seen in its price bracket.
Ready to perfect your joinery? The KM17 Pro is more than a plane—it’s a precision instrument.
