Using Paraffin On a Bandsaw

[JoeH]

Not wanting to argue, but I've cut a lot of metal on my bandsaw without coolant or lube and my bimetal blades last a long time. Granted I am not cutting with it 8 hours a day. I did use coolant when I had quite a bit of 1"x 6" hot rolled steel to cut but most of the time my work deals with smaller sizes.
I've never found my blade to get anywhere near hot enough to affect temper. I often check the blade after a cut and it is usually well within the easy to touch and hold range.
