Cool Blocks blade guides are made of a special, non-metallic material that lubricates your bandsaw blades as they cut, keeping them cool and reducing the chance of premature breakage. And since they won't damage blade teeth, you can really snug them down for added stability when working with smaller blades.

Cool Blocks improve the cutting performance of any blade width, but are required for blades 1/16" to 1/8" wide for tight radius work.
