90/180 Degree HSS Cobalt Containing Two-Stage Step Drill Bit Process Sinking Hole

Type C Center Drills, as defined by common industrial standards, are a specific category of combined drill and countersink tools. They are characterized by a design that creates a countersink with a curved (radius) bottom and is paired with a relatively short, robust pilot drill. This design is engineered for creating a specific type of center hole.

The "Type C" designation is part of a standardized classification system (e.g., Types A, B, C, D, R) for center holes and the tools that produce them, ensuring interchangeability and precision in manufacturing.
