COOL BLOCKS® blade guides are made from a high tech, non-metallic composite material, "Graphite Impregnated Phenolic Laminate", which contains three synthetic dry lubricants that lubricate the blade but do not make it oily.
The metal to metal contact made by old metal guide blocks creates heat and friction which cause premature blade wear and breakage. These problems are eliminated with COOL BLOCKS blade guides which allow blades to run cooler and last longer with less friction. COOL BLOCKS blade guides will improve the cutting performance of any blade width, but are especially effective with 1/16" and 1/8" wide blades for tight radius work.
