Bumping is a technique used to ‘bump’ the pins in a cylinder to the unlock position.
A bump key that corresponds with its target lock will have specially designed teeth which will transmit a slight impact force to all of the bottom pins in the lock when inserted and bumped using a bump hammer.
Duffells stock a wide range of bumping tools including bump key sets, dimple bump sets & bump hammers.
