Hole Dozer General Purpose Bi-Metal Hole Saw Set (20-Piece)

First time using a bi-metal hole saw and I was surprised how smoothly it cut through a solid oak door without binding. The 20-piece set gives you enough sizes for most jobs right out of the box.

I needed a clean 1-1/2" hole in some PVC pipe for a drainage project, and this 20-piece set made short work of it—the bi-metal teeth barely dulled after a dozen cuts.

Went through a stack of 3/4" plywood with the 1-1/2" bit and it barely slowed down. The bi-metal construction really holds up, and having 13 sizes in one set is super convenient for electrical work.

I've cut through some thick exterior siding with the 1-3/8 inch blade and it stayed sharp the whole way through. The bi-metal teeth handled the job way better than my old cheap set.

The 3/4 inch bit chewed through an old oak doorframe like butter, and the bi-metal teeth still look brand new. I’ve already used four different sizes—this set covers all the common holes I need for running cables and pipes.

Used the 1-1/2 inch bit to drill through some old steel piping and it went through cleanly without binding. The bi-metal teeth held up better than my last set from the hardware store.

Cut through some thick aluminum fence posts with the 1-1/2” bit and it didn’t bog down once—way faster than my old cheap set. The bi-metal teeth held up without chipping, which surprised me for a kit this affordable.

Bought this set to cut into a steel electrical panel, and the bi-metal teeth held up through all 20 holes with zero dulling. The variety of sizes covered everything I needed for that one job.

Cut through some old oak flooring like butter with the 3/4 inch bit—these bi-metal teeth really hold an edge. The set covers every size I typically need for electrical boxes and plumbing runs.

Pulled out the 1-3/8 inch size to cut a clean hole in some plywood for a new electrical box, and it went through like butter with zero binding. The set covers all the common sizes I need for home projects, which is a huge plus.
