Heavy metal will cut best with the 12/14. Blade will last longer.
14/18 TPI refers to the teeth per inch TPI. In this case 14/18 means that the TPI varies between 14 and 18 TPI. This gives you a better cut by providing the best of both 14 and 18 TPI
Junk! Harbor freight sells a better blade.
Hi Derek! The lower TPI on a blade is the faster the blade will cut through the material. The higher the TPI on the blade the slower it will cut through a material. The higher TPI will result in a cleaner cut.
It is a combination blade so it will cut a variety of materials. There is a set of teeth alternately spaced at 10 TPI and then a set spaced at 14 TPI. Has been a quality blade cutting both steel rod and aluminum.
Yes, I bought these band saw blades they work great !
Not a good choice. You need to use 8 to 10 tpi, or the newer 8/10 tpi "Thick Metal" bands for cast iron.
The blade is 1/2" wide and .020 thick.
Not sure the needed size but Most Craftsman tool require craftsman parts/consumables blades included (they usually use odd ball sizes only available from them)
