Emiko's Big Hole Mandrel

Emiko's Big Hole Mandrel is engineered for glassworkers who need precision control when forming large openings in beads, rings, sculptural forms, and core-formed vessels. The tool features a 2"-long stainless steel tube with a 5/32" mandrel handle, delivering 12" total length for optimal balance and control. The ergonomic design prioritizes both performance and safety. The thin handle enables faster rotations and smoother marvering compared to solid tubing, while remaining rigid enough to resist bending under working pressure. Unlike hollow tubing, the solid mandrel handle eliminates moisture entrapment that can cause burns during use. Available in multiple configurations: standard sizes feature 1/8" handles, while the extended 1-1/2" head version offers a 3" working length with a ¼" handle and 18" overall length for specialized applications. The solid rod end prevents mandrel release from filling the cored cavity, ensuring consistent results across repeated firings. A professional-grade tool built for serious studio practice.
