This stainless steel upgrade kit for the Hario Skerton coffee grinder produces a better, more consistent coarse grind by centering and stabilizing the lower burr. It installs with only a screwdriver. There is no need to remove the lower burr from the center shaft with this kit. This manual grinder works great for finer grinds, but if you want to use a french press or some other brewing method that requires a consistent coarse grind, this upgrade kit is a must. It greatly improves the consistency of coarser grinds by keeping the conical bur centered, resulting in an even gap between the two burs. This even gap is what produces a very reliable and consistent grind.
Some grinders have badly aligned burrs, which becomes apparent after you install the upgrade kit. Don't worry! With a little patience, you can get the burrs aligned and your grind nice and even.

This upgrade kit is for the Hario Skerton coffee grinder. It will NOT fit the Hario Skerton Pro coffee grinder, which has a completely different design.
