Description

Technical Field

[0001] The utility model belongs to the technical field of drilling processing, in particular to a special tool for chamfering a hole. Background Art

[0002] Drilling is an important method in machining, which uses drilling tools to machine through holes or blind holes with circular cross-sections on workpieces.

[0003] During the drilling process of parts, burrs will be generated at the position of the hole due to processing problems. The presence of burrs will hinder the fixation between the adapter and the flat workpiece surface, increasing the difficulty of assembly.
