Review on π PHITUODA Smooth Bi Metal Recessed Adapter by Scott Tompkins
Excellent Hole Saw for Drilling Lawn Sprinkler Heads
Used it today to drill twenty five 6 5/8 inch holes in my Bermuda grass to install concrete sprinkler donuts. The portable drill smokes at the first hole. I took out my 7.5A wired monster and solved this problem. I sprayed the inside of the crown with sprayed petroleum jelly.
Pros
- *Quality Assurance: The wall of the hole saw is made of bimetal, which increases its thickness, which improves wear resistance and increases hardness (β₯65HRC). Its surface is treated with a black coating that provides mild protection against rust and corrosion.
Cons
- Dear
