The Laguna Guide system achieves its superior stability utilizing 10 points of contact, 4 more than traditional guide systems. The ceramic material dissipates heat from the blade for longer life. The Laguna Guide is a revolutionary blade-guide system (several patents pending) that is designed to give you many years of superior high-quality band sawing. Most blade-guide systems are designed to support the blade on the sides as well as either above or below the side guides to support the back of the blade. This forces the blade to twist as pressure from the wood being cut is transferred to the back blade guide. This model is design for the Jet 18 bandsaw
