Turn any 9/16" [14 mm] hole into a precise and clean 16mm slot in your subframe clevis or axle brackets. The tool is designed to cut up to 10 ga mild steel. The low profile enables it to fit into spaces less than 1.5" [38mm]. Use this tool to quickly and cleanly slot subframe or control arm bracket holes allowing adjustment where the factory didn't provide any options. California Residents WARNING
