Center drills are specialized tools designed primarily for creating precise center holes (or starting holes) in workpieces. These center holes serve as accurate guides for subsequent drilling, tapping, or machining operations. Here's a breakdown of their characteristics and how they function:
Combined Drill and Countersink: Center drills typically have a short, rigid body with a drill bit tip and a countersink section (usually at a 60-degree angle).
How Center Drill Bits Work?
The basic principle of operation involves the following:
Securing the Workpiece: The workpiece is securely clamped or held in a vise.
Center Punch (Optional): For very precise centering, a center punch might be used to create a tiny indentation to guide the center drill's tip.
Drilling the Center Hole: The center drill is rotated at an appropriate speed in a drill press or other suitable machine. The drill tip creates a small pilot hole, and the countersink simultaneously creates a conical seat.
Subsequent Operations: The center hole then:
