550X and 551X Hole Saws: How to Enlarge an Existing Hole

Enlarging an existing hole has been simplified!
  1. Replace the standard XTREME FAST adaptor with one in the 550-PA05 Hole Enlargement Kit that corresponds to the thread type of your hole saw.
  2. Mount and fasten the larger hole saw. Next, insert and fasten the smaller hole saw inside it, made possible thanks to the long version adaptor.
    Note: the smaller hole saw corresponds to the dimensions of the existing hole.
  3. Start drilling. The smaller hole saw functions as a "guide pin".
  4. If desired, dismantle the smaller hole saw and finish drilling with the larger hole saw.
