GMauvaisUSA History

A French Micro Drilling Heritage, Supported In The U.S. By Pilot Precision

GMauvais traces its manufacturing heritage to 1928 in Annecy, France, where ultra-precision micro drills were produced for the Swiss watch industry. Today, that same focus on micron-level precision continues through Gabriel Mauvais SARL and its U.S. distribution partnership with Pilot Precision Products.

1928 Manufacturing Heritage

GMauvais began producing ultra-precision micro drills for the Swiss watch industry, where extremely small drills and micron-level tolerances were essential.

Precision Holemaking Focus

The company expanded its product range while maintaining a core emphasis on precision micro drills, ground cylinders, and specialty cutting tools.

Modern Gabriel Mauvais SARL

Incorporated in 1997 and located in Villaz near Annecy, France, Gabriel Mauvais SARL manufactures tools in tungsten carbide, cobalt high-speed steel, and medical stainless steel.

U.S. Support Through Pilot Precision

GMauvais products entered the U.S. market through Hassay Savage. Today, Pilot Precision provides exclusive U.S. distribution, inventory, engineering support, and technical assistance.

Manufactured for Consistency at the Micro Level

GMauvais differentiates itself through proprietary turning, grinding, flute grinding, heat treating, and precision sharpening processes. Its production systems emphasize dimensional consistency, surface finish, concentricity, straightness, and repeatability, with many tools manufactured to tolerances measured in only a few microns.
