Description:

A Sprue Cutter is a tool used to cut openings in your sand mold to use for pouring in molten metal. The sprue cutter forms a clean, tight, opening that connects to your runner or gate. It can also be used to cut risers.

Straight Sprue Cutters compress the sand less during insertion and are less likely to disturb the mold. This is a larger diameter sprue cutter which is typically used for pouring heavier parts that require an increased pour rate and larger hot metal reservoir to prevent shrinkage.

Material: Solid Copper, Soldered Copper Ring, Black Painted


How To Use It:

After ramming up both the cope and drag with molding sand the sprue cutter is pressed into the sand to cut a path thru the cope into your mold. Then the mold is opened, and gates or runners are cut to connect your mold cavity to the sprue channel. The sprue cutter can be pressed in farther than the parting line to create a catch basin in the drag half to stop sand that might get washed off during pouring from entering the mold cavity. After pressing in the cutter give it a 1/4 turn and pull it out.
