Review on LANIAKEA 100mm Concrete Hole Saw: Efficient Drilling and Precision Cutting by Logan Collier

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.
