"Spot weld cutters are specialized tools designed to remove spot welds efficiently and accurately. Spot welds are commonly used in automotive and metal fabrication industries to join two metal panels together, creating a strong bond. However, when repairs or replacements are necessary, spot welds need to be removed without damaging the surrounding metal. Spot weld cutters typically consist of the following components: Cutting Head: The cutting head is the main part of the spot weld cutter. It is a cylindrical or cylindrical-conical-shaped bit with sharp teeth or edges. The cutting head is designed to penetrate through the outer panel, reaching the spot weld and cutting it apart. Shank: The shank is the portion of the spot weld cutter that connects the cutting head to the drilling machine or power tool. It is often cylindrical or hexagonal in shape to fit securely into the chuck or collet of the drilling machine. Pilot Pin: Some spot weld cutters have a pilot pin attached to the cutting head. The pilot pin acts as a guide, ensuring precise alignment and preventing the cutter from wandering or slipping during operation. It helps maintain accuracy and prevents damage to the surrounding metal."
