Home improvement measuring tool for reliable radius checks, the LiebeWH Radius Gauge handles both external and internal curves. Confidence grows when replacement parts match and 3D-printed components sit flush. Is it the right choice for professionals and hobbyists who need repeatable, rust-resistant measurements?

⚡ At a Glance
  • Measuring Accuracy: Dual concave and convex leaves allow comparison against internal and external radii with clear size markings
  • Best for: Machinists, toolmakers and makers refining parts or checking fillet weld radii
  • Not ideal for: Users who require electronic readouts or micrometre-level digital measurement

High-quality stainless steel construction with two leaf types suits convex and concave surfaces. Clear markings and multiple measuring ranges support workshop and 3D-printing workflows.


Accurate internal and external checks – With dual concave and convex leaves

Concave leaves match internal radii while convex leaves sit against external curves, and each leaf is clearly marked with its radius value. Rapid visual comparison avoids the need for transfer gauges.

Verify fillet radii on tools, welded joints or printed parts quickly, reducing trial-and-error during fitting and finishing.

Long-lasting corrosion resistance – Thanks to high-quality stainless steel

Stainless steel construction resists rust and preserves leaf geometry even after regular use and exposure in workshop environments. Minimal maintenance is required to keep edges true.

Durable build withstands everyday workshop conditions, making the tool reliable for repeated checks over time.

Faster size selection – With clearly marked leaves

Each leaf is stamped or etched with its radius so users can identify the correct size at a glance without additional measuring tools. The two-leaf system removes the need to flip or swap multiple single-purpose gauges.

Speed up routine measurements and reduce setup time when matching parts or adjusting designs.
