FIELD: soil or rock drilling; mining.
SUBSTANCE: group of inventions relates to drill bits and methods for production thereof. Drill bit includes a stationary body, a rotating member, a first seal surface and a non-elastomeric seal member exposed to a lubricant. Non-elastomeric seal member comprises a first end having a second seal surface that is in contact with the first seal surface, a second end that is fixed and a bias member between the first end and the second end. Non-elastomeric seal member is a one-piece member constructed using a single metallic material.
EFFECT: technical result is an elastically deformable seal that is resistant to temperature.
