PCB micro drill bits are classified according to the shape of the front end. Type UC is a drill bit in which the outer diameter of the rear end of the drill body is processed into a smaller diameter.

UC (Under Cut) drills are a specific type of PCB (Printed Circuit Board) drill bit designed to create holes with an undercut profile. An undercut hole is one where the opening on one side of the PCB is wider than the opening on the other side, creating a conical or tapered shape.

These drills are commonly used in PCB manufacturing processes where the creation of undercut holes is necessary for specific applications, such as creating space for components with angled or protruding leads, or for creating a secure mechanical connection between the PCB and other components.

type	Series	Diameter	Features
UC	UA	Φ 0.0750 ~ Φ 0.350 mm	Excellent Hole Accuracy
UC	UH	Φ 0.0750 ~ Φ 0.350 mm	Excellent Hole Wall Quality
UC	UHA	Φ 0.0750 ~ Φ 0.350mm	Balance of hole accuracy & hole wall quality
UC	UC	Φ 0.300 ~ Φ 1.200mm	General Purpose

UC drills typically have a special cutting geometry that allows them to remove material from the PCB substrate in a way that creates the desired undercut shape. This may involve a combination of cutting edges and flute designs that facilitate the controlled removal of material while maintaining precision and accuracy.

UC drills play a crucial role in PCB fabrication processes where precise, specialized hole profiles are required to accommodate unique component configurations or assembly requirements.
