Breville’s self-leveling force-gauge tamper in the 58mm size. Because it is
58mm, it pairs with Breville’s three 58mm machines — the Dual Boiler, Oracle
and Oracle Touch — not the 54mm Barista/Bambino line. Being a standard 58mm
tamper it also suits any 58mm commercial-standard portafilter. Verified
