Pilot punches are used in progressive dies as a locating tool. When a punch pierces a hole in one station, the press cycles the die and the material is moved to the next station. The pilot punch enters the hole and positions the material in an exacting location before the press cycles the next stroke. Precision Punch pilot punches are ideal for tool designers that desire close tolerance, long lasting, accurate pilots in high production and high-strength materials. These pilots may also be used for extrusion applications.
