Facom Automatic Center Punch (257A) - Simply press the end to release spring impact. I stock the USAG version (identical to Facom) as it is much cheaper and carries a US warranty. The Facom version is a "special order" item.

• Impact adjustable by turning the knurled head.
• Acceptable load: 11 to 22 kg.
• Chrome body with spring loaded tip
• Length: 163 mm, body Ø 16 mm, shank Ø 7 mm.
• Weight: 0.135 kg.
• Interchangeable tip: 257.07.
• Spare tip: 257.10A.

Note - I keep one of these in each of our car's glove compartments. In an emergency, these will easily break the window glass should you become trapped in your car.
