FIELD: process engineering.
SUBSTANCE: set of inventions relates to drill bits, their production and applications. This drill bit has at least one profile of the blade cutting part with conical section and at least one cutter thereat extending from extended position to male position when load applied to drill bit equals or exceeds limiting value. Note here that drill bit cutting depth is larger in female position than that in male position.
EFFECT: higher drilling efficiency at curved and straight hole sections.
