While you can lubricate a metal band saw with oil — or even use a flowing cooling fluid to keep it cool — that kind of moisture would collect sawdust and damage wood in woodworking applications, Olson offers a “cool” alternative: small blocks made of graphite-impregnated phenolic laminate. They lubricate the blade, but don’t leave it oily.
By reducing the heat from the metal-to-metal contact caused by using normal metal guide blocks, Cool Blocks help to reduce blade wear and breakage. Also, because the blocks give more easily than their metal counterparts, they’re less likely to shear off damaged blade teeth when they pass through.
When we did some quick Googling to see what others thought about Cool Blocks we discovered that they’re at the top many heavy bandsaw users’ “first upgrade” lists. They’re available all over the next starting at around $14-$16 — size and price varies slightly based upon your specific saw model — though you can pick them up at Rocker’s or other local stores as well if you’re too impatient for shipping.
