QC Knurled Nut w/Shoulder

Sherline Products, in collaboration with Bryan D. Drummond (Gem Cutter & Goldsmith), has designed this DOP Holder specifically for securely holding lapidary DOP sticks during gemstone cutting. If you already own one of our machines, the holder is designed to thread directly onto our ¾-16 headstock spindle nose. It will also be an essential accessory for our upcoming gem cutting machines.

Compatible with Ultra Tec® Dops This DOP Holder has been precisely engineered with tolerances and a keyed dop system designed for compatibility with Ultra Tec® brand dops which are used on their faceting machines. Many gem cutters use Ultra Tec equipment for flat faceting, and the keyed dop feature provides secure alignment and ease of use, making it a valuable addition to your setup. Sherline does not manufacture dops, but they can be purchased directly from Ultra Tec. Like Sherline, Ultra Tec products are high-quality and Made in the USA. Shop Ultra Tec Dops  Features:
