There are a few things you should do when you get a new cold saw blade to get the most out life out of it.
Coolant
The first thing is to make sure you are using good coolant. Coolant is a huge part of the cutting process when using a cold saw. The coolant is not actually what helps the blade or material stay cool when cutting. You could cut without coolant and the material would still be cool to the touch. The coolant is necessary to prolong the life of the blade. It's a lubricant which is important to help the blade's teeth last longer between sharpening. Cold saw coolant also helps to keep pitch or your material from adhering to the sides of the cold saw blade or inside the gullets.
Breaking in the blade
A fresh cold saw blade, new or resharpened, needs to be broken in before it is used as normal. If a blade is not broken in, you could risk premature dulling. The way to break in a new cold saw blade is to feed it slowly through the material for the first few cuts. We recommend half the feed rate for about three to four cuts. Usually four cuts is good enough. This will extend the life between sharpenings.
