As a supplement to our thread gauge system, Leitech Instruments produces Core Hole Gauges for control of drilled holes before thread tapping.

Leitech Core Hole Gauges are available in all versions: High-resolution, Combi, Digi, and Traditional Gauge.


For these products, we offer a specially constructed removal sleeve tool. Also, we offer a special tool for calibration. Prices are available upon request.
