4 Piece CNC Groove Grinder/Sifter

Featuring innovative coaxial turbine technology, Groove by Aerospaced has changed the nature of grinders as we know them. Through its proprietary design, Groove requires minimal material preparation and delivers a coarse grind, naturally separating unwanted material for optimal consistency.

How it Works

Remove top lid and place material on grooves, replace lid and then rotate back and forth until the material is fully ground. Open bottom chamber to access your freshly-ground material.
