Which grinders it fits

SSP (Sung Sim Precision) is a Korean burr manufacturer that produces aftermarket replacement burrs for most major professional grinder platforms. This 80 mm set is the screw-mount version, made for the Ditting 804 and 807 and for the Mahlkönig E80 and Peak, which use the same burr mounting. On those grinders it is a direct replacement for the stock burrs: same outer diameter and the same screw pattern.

What the HU geometry does in the cup

HU stands for High Uniformity. The geometry is designed to produce a tight particle size distribution with a medium amount of fines. In practice, that means stable pressure during espresso extraction, a dense and well-defined body, and a high-concentration cup with classic espresso character. It is a good match for traditional espresso, medium and medium-dark roasts, and for users who want a syrupy, full-bodied shot rather than the brighter, tea-like clarity that low-uniformity burrs tend to produce.

SSP also makes the same 80 mm set in an LU (Low Uniformity) geometry, which makes fewer fines and flows faster. LU leans toward filter brewing and brighter, lighter-roast espresso. If you’re unsure which to pick, HU is the more forgiving and traditional choice.

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, with two practical effects: the burrs stay sharp 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

Not every 80 mm grinder takes screw-mount burrs. The Mahlkönig Tanzania and Ditting 805 use a blind two-pin burr, and the current Weber Workshops EG-1, Option-O Lagom P80 and Zerno Z2 use a blind burr of their own, so this set fits none of them. For the EG-1, P80 and Z2 we stock SSP’s 80mm blind burrs in HU and LU. 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 80 mm burrs on a Mahlkönig or Ditting grinder is a straightforward job for anyone comfortable opening the grinder, but you will need to dial back in afterwards and zero the burrs to find the new contact point. Most users report a brief seasoning period of 5 to 10 kg before the cup profile fully settles. Use of non-OEM burrs may affect the grinder manufacturer’s warranty, which is worth being aware of before installation.
