Which grinders it fits

SSP (Sung Sim Precision) is a Korean burr manufacturer that produces aftermarket replacement burrs for most of the well-known professional grinder platforms. This 80 mm set is the screw-mount version for the Ditting 804 and 807, and a direct replacement for the stock burr set on those grinders: same outer diameter, same screw pattern. Mahlkönig’s E80 and Peak are built on the same 80 mm platform, but SSP also makes a separate Lab Sweet set listed for the E80, so contact us before ordering for one of those grinders.

The geometry here is SSP’s Lab Sweet (LS) profile, sometimes called the “cast steel” geometry because it deliberately moves away from the very tight, uniform particle distribution of modern high-uniformity burrs and toward something closer to vintage cast burrs. In the cup, that translates to a heavier body, more perceived sweetness, and a slightly wider range of particle sizes. It is a good fit for medium roasts, light-medium roasts where you want sweetness rather than ultra-clean clarity, and for baristas who find ultra-uniform grinds taste a bit hollow.

How it compares to the HU version

SSP also makes a High Uniformity (HU) set for the same grinders, which we stock as the SSP 80mm High Uniformity burrs. HU gives a tighter particle distribution and dense, stable espresso. The LS set trades some of that precision for a rounder, sweeter, more textured cup and a wider sweet spot when dialling in. Neither is objectively “better”; it’s a flavour preference.

About the Red Speed coating

Red Speed is SSP’s TiAlCN (Titanium Aluminium Carbon Nitride) coating. It increases surface hardness and reduces friction at the cutting edge, which has two practical effects: the burrs stay sharp for considerably longer (SSP rates its coated burrs at 4,000 to 5,000 kg of coffee, against 1,000 to 2,000 kg for uncoated steel) and they generate less heat during grinding, which helps preserve aromatic compounds in the bean. The coating itself doesn’t meaningfully change particle distribution; that’s set by the geometry.

Specifications

Blind-mount grinders need a different set

This set does not fit the Mahlkönig Tanzania or Ditting 805, which use a blind two-pin burr, or the current Weber Workshops EG-1, Option-O Lagom P80 and Zerno Z2, which use a blind burr of their own. We stock SSP’s 80 mm blind burrs separately for the EG-1, P80 and Z2. If you are unsure which you have, look at your current burrs: screw holes through the grinding face mean this set fits, no holes mean it doesn’t.

Notes on installation

Replacing burrs on a Ditting 804 or 807 is straightforward but does require dialling the grinder back in afterwards. Plan for a small amount of seasoning before judging the cup: most users report that SSP burrs settle in over the first 5 to 10 kg of coffee, after which the flavour profile stabilises. Use of non-OEM burrs may affect the grinder manufacturer’s warranty, which is worth being aware of before installation.
