1 x Arbor
1 x 82mm length centre drill
The Duoxim Arbor is an innovative system for
enlarging existing holes. Perfect for expanding
holes for downlights in ceilings, the tool
couldn’t be easier to use. Simply replace your
smaller size hole saw with the desired larger
size via the arbor screw thread, then add the
original hole saw over the top. Using your first
saw as a guide, drill over your original hole to
enlarge.
