摘要

Device for measurement of temperature in zone of treatment of article, mostly on cutter blades of drill, has temperature indicator arranged as thermo-couple made of connected with one ends metal wires that have different resistance to electric current, are in contact with heated place under investigation, output ends of those are connected to registering apparatuses. Connected to each other ends of wires of thermo-couple go through long channel of drill and are welded to its output opening placed at the back section of working section of the drill.
