Stone Assistance has several test benches , experimental prototypes that have been developed for specific applications . They are used to assess the performance and efficiency of cutting tools and drilling tools , as well as measuring certain mechanical properties of materials. These devices are unique in their kind 

Shaper for carrying out linear cutting and wear tests

Tower instrumented for making circular cutting and wear tests



Drilling bench for smaller tools (<25 mm in diameter)



Drilling rig for superior pruning tools (25 mm < <180 mm )
