The Macap M4D Digital stepless coffee grinder features the same internal mechanisms as the M4 Manual and M4 Timer, as well as offering a digital screen with programming options. This means that it is powered by a 250 watt motor, which spins the 58 mm grinding burrs at 1400 rpm. Like all Macap grinders and tampers, it is designed and manufactured in Italy, the birthplace of espresso. The Macap M4D stepless grinder has a tinted bean hopper that holds over a pound of whole beans, and uses flat burrs to crush the beans evenly and consistently. The M4 Digital combines the power and great design of the other Macap M4 grinders with the control and convenience a digital programming screen offers.
