🌐 Lanaikea 4: The Ultimate Networking Solution for Seamless Connectivity Review

I used a 100mm concrete hole saw with an SDS impact hammer to drill holes in 4" thick concrete blocks. By the time I was halfway through the fifth hole, the tips were blunt and he wouldn't move forward. At $1.50 an inch of material this allows me to drill a hole, it's not worth the money.

I needed a 4-1/4 inch circle cut through two pieces of drywall so I could vent hot air. This cut is not a problem. Not sure how hard it is, you can punch drywall so it doesn't take long to get the job done, but got two good laps, no complaints.

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.
