UPDATE 2: apparently this guide works for the KG89 model too however you will not want to adjust it quite as far as with the KG79.

UPDATE: Two years later of daily use and my grinder is still going strong! makes me wonder why they didn't allow it to grind finer in the first place.

one thing of note is to remember to clean out the grinders burrs and the grind chute (remove collection box and it's at the top back) using a dry brush more often than usual to prevent clogging.

HowTo: Make A Cheap Electric Espresso Grinder Using A DeLonghi KG79 / KG89


Having a good coffee grinder is essential to producing a good cup of the black stuff (but most of us simply don't have £200+ to spend on such a device) and here is a cheap and simple way of producing a nice fine espresso grind using a readily available De'Longhi KG79 Burr grinder which can cost as low as £30.

What You Need:

De'Longhi KG79 Professional Burr Grinder
Small Flat Head Screwdriver
Medium Philips Head Screwdriver

Thats it!


1) Set the coarseness to fine and the cup size to 2 and remove the lid, the coffee bucket, and the Burr itself.
2) HARD PART: Prize off the 2 knobs using a small flat head screwdriver, work your way all the way around each one till eventually they pop off.
3) Remove the outer shell by simply unclipping it on the bottom using the flat head screwdriver in the small cutouts and lifting it up and off.
4) Undo the top 4 screws which are holding the coffee feeder in place and remove carefully.
5) Undo the 4 screws on the cap over the coarseness spindle.
6) Using the square outer part where the knob goes as a guide, carefully lift up the spindle and rotate it 1 flat side at a time clockwise (rotate 2 sides, this is changing what was the finest setting on the dial back out to about 3/4 coarse but without actually moving the burr!).
7) Put the cap back on and screw back up.
8) Now using the knob, rotate the coarseness anti clockwise till it stops at its new much finer level.
9) That's it, You have now adjusted your coffee grinder so that it can grind a full half turn of the knob finer than it does out of the box!
