Review on Cle Line C25099 1887 Speed Steel by Brandon Vox

Put it on a drill and it will tumble like a drunk investment banker. Approximately 2 mm for every half turn. It burns and smokes. This is definitely a saw because the mandrel is straight and the same mandrel makes good clean holes with other saws. Difficult to remove the plug. Don't buy the cheapest hole saw unless you really care about the hole size!
