A classic shape pepper mill, designed in 1975 and is still popular with households today, The 505 mills feature a hardened carbon steel mechanism for pepper and diamond sharp ceramic mechanism for salt and come with a lifetime guarantee. Adjust the grind from fine to coarse by tightening or loosening the knob on the lid. The Cole & Mason Precision mechanism does not crush peppercorns but strips them to release the maximum amount of flavour with each turn. We recommend using high quality peppercorns and coarse rock salt in all our mills.
