Good value - 4 " brick holes for light boxes

I wanted to install a light on brick garage paneling. Apparently this was an option the original buyer didn't want and finding a contractor to do it is difficult. I'm something of a handyman and my biggest fear was that this 4 inch blade would be exactly the same outside size as a 4 inch lightbox. I took an old cinder block and cut a hole and to my delight the light box had a tight tolerance perfect for the box the light will be hanging from. Cuts better and the cutting speed shouldn't be slow…

Pros
  • Efficient cutting of hardened steel, fired ceramics, cementitious aggregate, non-metals and other difficult-to-cut materials
Cons
  • Not bad, but...

Good quality tool but success requires patience

I bought this hole saw to drill a hole in porcelain stoneware 300 x 300mm for installing a shower thermostatic mixer. I've watched YouTube videos of others cutting large diameter holes in tile with a diamond blade on an angle grinder, but I wanted a cleaner result. I used the drill press with the tile in a shallow plastic pan filled with water to oil the cut and keep everything cool. Like all large hole saws, this one needs a pilot drill to keep it from wandering, so I bought a Starrett XA2…

Pros
  • Always use coolant and start at low speed, increase speed as the cut becomes easier avoiding overheating of the cut surface
Cons
  • No power

Worked great. Cut 12 inches of reinforced concrete for a 4 inch round patio drain.

Just wanted to drill a 4.25" hole in a 4" thick concrete deck to install a 4" stormwater drain line. The spot I chose for the hole turned out to be a full 12 inches of 3,000 psi concrete that was as hard as rock. This hole saw cut right through him. I used a 1/2" Sears bit, which worked well. I used a garden hose to fill the hole and didn't apply too much pressure, pausing for a few seconds about every minute to make sure the water drained drained to cool the teeth of the hole saw. It took some

Pros
  • Clean, efficient cuts and longer life
Cons
  • Some small things
