Review on Milwaukee 49 56 0057 16 Inch Hardened Hole by Chuck Cromer

Based on my observations, this hole saw is a real workhorse. It easily cuts through thick materials and maintains its sharpness throughout multiple uses. The hardened coating makes it durable and long-lasting... The only DOWNSIDE is that it can be a bit pricey compared to other hole saws, but the quality makes it worth the investment..
