The Star Blue Dry Hole Saw is a dry-cor-bore bit made for drilling through brick and soft block material, where wet cutting is impractical or unavailable. It delivers good cutting life using quality diamond segments, built with a slot-vented core body to enhance cooling during dry operation. It is not designed for use in hardened concrete, steel-reinforced slabs, or very heavy masonry materials. Ideal for electrical, plumbing or HVAC work where dry holes are needed for conduit, penetrations, or anchor installations.
