Combination Angle Indicator/Center-Locating Punches for Curved Surfaces

Dial with Four 90° Quadrants

360° with Clockwise Dial

360° with Counterclockwise Dial

Find the center of square and round materials, such as structural framing and pipe, and determine setup angles on milling machines and grinders.

Use the clockwise dial for moving in a counterclockwise direction. Use the counterclockwise dial for moving in a clockwise direction.
