As an industrial and scientific professional, I have used many hole saws over the years, but this one stands out. Based on my experience, this bimetal circular construction plumbing carpentry hole saw is of outstanding quality. It drills through wood, metal, and plastic with ease, and the cuts are clean and precise. Its durable construction also ensures that it lasts longer than other hole saws I've used. The only downside is that it's a bit pricier compared to other options, but it's definitely worth the investment.
