Stainless steel drill bit depth stop for 9mm drill bits..
This is an essential tool we use in the workshop when fitting panels. It's especially useful when drilling 9mm holes for Rivnuts, as it prevents the bit from going too deep-protecting any outer skin or surface behind the panel from accidental damage.
Ideal for use on rear door upper panels, interior panels, and similar applications where precision and control are critical.
