Description
The ToolCurve DF 500 Imperial Thickness Gauge is a direct replacement for the factory metric thickness gauge, designed specifically for woodworkers who work in imperial measurements.
This simple upgrade eliminates metric-to-imperial math, allowing faster, more confident height adjustments when working with common North American board thicknesses. Less thinking, fewer mistakes, and smoother workflow at the bench.
After extensive feedback from woodworkers, this updated version focuses on clarity, durability, and ease of use. The improved indicator is easier to read under shop lighting and built to hold up to daily use.

Very nice products to fill holes from manufacturers
Something so simple is so great. I tried to covert yo metric, but it’s a struggle, so I’m an imperial guy.
Works great to not have to convert from metric. Easy switch over. Great addition.
I don\’t mind the metric system; I just don\’t \”think\” metric. Having this replacement gauge for my Festool makes thinking about a project much easier. Not to mention the build quality of the little item. Very thoughtfully done.
Glad I don’t have to figure out the metric measurement anymore.
