Review on Efficient and Durable NINIA Heavy Cutting Bi Metal Cutter - Superior Cutting Tools for Precision Cuts by Shawn Parker

I bought this hole saw about an hour after comparing reviews, features and price. This seemed like the best all round choice and I can say it worked. I cut standard 5" holes in MDF and plywood with an old hole saw that I've had for about a year and I will say that I bought the entire set of saws for about what I paid for this new hole saw . Get what you pay for I guess! I was used to custom holes and just used my sander to smooth out the imperfections. This hole saw cut my holes the way they should be, clean, crisp and straight. You can see in my photos the difference in the piece that came out after the cut. The old saw broke circles very badly, and this thing cut like a hot knife through butter. I am very happy with my purchase and if I need a different size crown I will look to this brand.
