Abstract

Improvements in the construction of facilities for sharpening bits, bits that comprise at least one main edge and each time a free surface assigned to a main edge and a groove for the exit of shavings, said facilities being of the type that comprise at least one rotary wheel with at least one sharpening surface, means for actuating the grinding wheel, a guide piece arranged in front of the sharpening surface, in which at least one guide channel for inserting a drill bit is placed and that allows the bit to rotate around its own axis, and at least one guide stub arranged in the guide channel, intended to fit into a groove for the exit of chips from an inserted bit, and to limit the rotation of the drill bit in the guide channel, characterized in that two cone-shaped sharpening surfaces are provided, designed to simultaneously machine the main cutting edges of the bit.
