1 LB Lead Balls (For Milling)

Lead balls of 0.49 inch diameter, sold by the pound as grinding media. Lead is dense and non-sparking, which is why it remains the traditional media choice for ball milling materials that must not be exposed to friction sparks.

The balls are used in ball mills and rotary tumblers to reduce dry powders to a finer particle size and to blend materials evenly, and their consistent size and weight give uniform milling action. Lead is toxic: handle the media with gloves, keep it away from food areas and wash after use.
