Review on 🔄 Laniakea Bi-Metal Variable Holesaw with Annular Design by Richard Counts

I bought a 4 1/8" hole saw to cut holes for 4" flush mount LED lights. Worked great! Today I cut 13 holes and no signs of dullness are visible. The tiered slots on the side are thoughtful as they provide a handy grip to insert a screwdriver to pry out the scrap. It also allows you to look inward to align the pilot drill. I have no criticism and nothing but praise. I've used it on plywood, but it will probably work just as well on drywall.
