Review on RUKO 106152 Speed Steel Bi Metal by Patrick Hamman

RUKO's bi-metal hole saw exceeded my expectations. As my tests showed, it cut through metal and wood with ease, and proved to be exceptionally durable. The bi-metal construction ensured that the saw remained sharp through frequent use, thus increasing efficiency and reducing downtime. The product is an optimal choice for cutting JOBS in both industrial and scientific environments .The only downside was that the saw`s teeth tended to snag on harder metals, though this was not a major issue..
