Used commonly within the scientific Glass-Blowing industry, Planetary chucks on lathes allow faster gripping/release of delicate items with a greater control of pressure.

Starting back in 2022, Benthams’ developed in conjunction with Bee Hardy Glass a new updated design of high precision Donut interlocking adapters, fondly known now as Benthams’ D’Nuts.

These fully interlocking chuck adapters quickly and easily fit around the 3 round jaws of the planetary chuck allowing them to grab items of much smaller diameters than otherwise possible and thus work on finer precision glass rods and tubes that would otherwise require manual manipulation.

The way we manufacture these interlocking D’Nut adapters for stock here in the UK allows for a custom bore size to suit any diameter of jaws,
