Just purchased a 6" horizontal/vertical bandsaw from KBC tool in Canada. Believe it to be the same unit as Craftex, King Industrial and General Machine. My question is,,,,, it has a coolant system but I have read the entire "vaque" manual and while it tells me to insure the coolant and filter should be kept clean; and don't use oil/water mixed coolant for certain materials it does not suggest what coolants you might use. The main use will be to cut angle iron and square steel tubing. What should I be looking at for coolant. Any help would be greatly appreciated!
