M42M Espresso Grinder by Macap

A customer favorite for it's price point and durability, the M42M grinder by Macap is an on-demand grinder with a small footprint. The fingerguard of the bean hopper has been redesigned to help beans flow through easier while still protecting your fingers. The adjustment dial numbers a printed with a light color which makes it a lot easier to read.

Dual Mode

The M42M can switch between semi-automatic and on demand grinding. On the right side of the grinder, there are 2 switches. The one on the right is the power switch. The one on the left switches between the 2 modes. The “M” position is for semi-automatic grinding. The “T” position is for on demand grinding.

Programmable Functionality

To the right of the coffee chute is the programmable adjustment knob. It adjusts the length of time when grinding on demand. Turning clockwise to a lower number will decrease the grinding time. Turning counterclockwise to a higher number will increase the grinding time.

On Demand Dosing

The red button underneath the coffee chute grinding process. When semi-automatic grinding, press and hold until you have the amount of ground coffee desired. When grinding on demand, press once for a single dose or twice for a double dose.

Stepless Grind Adjustments

No matter the size, you will be able to dial your shots in with ease with the stepless adjustments. We suggest this grinder for small to medium volume establishments.
