Cool blocks are the blade guides on a bandsaw. There are ones above the table and a below. They will keep the blade running true and thus they will occasionally (or frequently depending on how well tuned your bandasw is) touch the blade sides while moving. This creates friction which heats up the blade which causes snaps or to mess with the temper which causes blades to dull faster. So your cool block should be made of material that doesn’t heat up easily or at least leeches the heat away from the blade.

More expensive blade guides use bearings instead of blocks and spin instead of rub against the blade.
