The drill used to make the small holes in the hydraulic cylinder is an Acetylene Welding Tip Drill. Most welding supply stores carry them. Just ask for a Tip Cleaning Drill.
Has several of the small drill bits stored in the handle. Caution: Do not open the storage cap over carpet. The really small bits can disappear, if you drop any, until you find them with your bare feet.
