Avid piston drill set 1.1 to 2.0mm
Avid’s new piston drill set includes twist drill bits between 1.1mm and 2.0mm in increments of 0.1mm, ideal to modify existing or custom-build new shock pistons. The set comes with a handy drill bit holder so owners can easily drill custom pistons by hand. The tools come in a convenient box that has a color-coordinated label, allowing to quickly figure out the drill bit size if they get out of order.
