You ABSOLUTELY need coolant for sawing!!!!!!!!!!!!
If you're going to change your blade speed, make sure you can adjust the speed...if you have a steel saw blade, your blade speeds may need to be as low as 100 feet/minute for some tool steels...other steels you can be in the 250 feet/minute range. For aluminum, 300 feet/minute works well.
You sawing speed will also depend on your blade and the rigidity of your saw. |
