58.35mm with Thread The Espresso Tamper 2.0 has been optimized for internal structure without changing the 30lb poundage, making it easier to remove and install. A 15lb spring is presented to meet different users' needs. TAMPER WITH THREE SPRINGS: The MHW-3BOMBER espresso tamper uses an original three-spring design, which not only maintains a constant pressure of 30 lbs, but also provides sound feedback.

And when should I stop tamping powder?" ERGONOMIC HANDLE: When you tamp, your fingers will have a contact surface, which can be more comfortable when tamping. The handle combines wood and metal, elegant and delicate. Product Simple Operation Disassemble components from right to left sequentially. Remove the internal pin.
