The Avid piston drill set includes twist drill bits between 1.1 - 2.0mm in increments of 0.1mm. Comes with a handy drill bit holder so you can easily drill your custom pistons with your hand. We then topped it off with a convenient box that has a color-coordinated label so you can quickly figure out the drill bit size if they get out of order.

Tips

• The large collet for the drill bit is not always in the drill bit holder, you may have to pull the end off to get the largest collet out for these bits.
• Do your best to keep your drill bit going in straight and let the drill bit do the cutting by not pressing down too hard. These bits are thin and will snap but if you break one just let us know.
