摘要

Conicity checking instrument, particularly for cones of drill bits, bits, and similar tools, essentially comprising on a support the assembly of three longitudinal plates with the particularity that they have one of their longitudinal edges free and convergent with respect to the corresponding the other plates, so that these determine planes whose free edges fit perfectly to the generatrix of a conical surface.
