Review on LANIAKEA 100mm Concrete Hole Saw: Efficient Drilling and Precision Cutting by Norman Costello

Revainrating 5 out of 5

It cuts through my drywall with no problem. It was the right size for the dryer exhaust vent.

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.

Pros
  • Power Tool Parts and Accessories
Cons
  • Can't remember
