Holesaw jig

I designed a hole saw jig for enlarging existing 60 mm holes for downlights.  The jig acts as a guide bushing that fits the pilot drill bit to ensure precise alignment with the existing hole allowing for a clean cut. 
This tool is ideal for upgrade or replace downlights with larger models.
