Carbide Drill Bushings | K20/K30/YG8 Grades | Manufacturer

The drill bushing is a type of machine tool fixture primarily used for guiding cutting tools precisely during drilling or reaming operations on workpieces. Depending on their purpose and functionality, drill bushings can be categorized into fixed, replaceable, quick-change, and specialized types. These fixtures not only ensure the accurate positioning of tools but also effectively prevent vibrations or tilting during machining, thereby safeguarding the precision of the hole locations.

Drill bushings made from cemented carbides are particularly favored due to their ultra-high hardness, exceptional wear resistance, good toughness, heat resistance, and corrosion resistance, along with a significantly longer lifespan—often more than thirty times that of standard bushings. Cemented carbide drill bushings can even operate stably under high-temperature conditions, greatly enhancing work efficiency.
