These durable, ergonomically designed flask tongs have carbide-tipped jaws that grip 3-1/2" flasks securely, yet reduce defects resulting from squeeze pressure applied to hot flasks. The tongs have a squeeze grip at the end that allows operators to keep a safe distance from the heat of the oven. Effective for use with a wide variety of casting machines, these tongs are specially designed for use with all Neutec® casting machines.
