Description:
These are generic eureka blades, not original but will fit and act the same way - for original see below

If you can't get the grind any finer, then you need to replace the blades.
Your new blades are sharper and will deliver a finer grind, so you will have to adjust your grinder after you replace the blades.

Size: 30mm x 50mm 7.5mm thick
Type: 3-hole, right-hand rotation

Includes: 2 x Flat blades

Note: It is common for grinder blades to have "spots of oxidization from exposure to air; this does not mean that the burrs are used or inferior in quality in any way.
