Product Description
This listing is for the magnetic two-piece adjustment knob only.
Grinder, dial, and other accessories are not included.
This is an upgrade accessory for the ARO® Grinder Setting Dial for Eureka Mignon .
The ARO® Magnetic Two-Piece Aluminum Grinder Adjustment Knob allows you to access your grinder for cleaning and servicing without losing your grind setting or needing to re-zero when using the ARO® Grinder Setting Dial for Eureka Mignon .
With our standard one-piece knobs, the knob must be fully unscrewed to gain enough clearance to remove the top cover plate. This forces you to lose your grind setting and re-zero the grinder after reassembly.
Magnetically coupled two-piece design eliminates that problem entirely. The top section separates instantly while the lower section remains fixed in place, allowing the cover plate to be removed while your original grind setting stays exactly where it was.
The square interface and four-position gear symmetry ensure the knob always reattaches in the exact same orientation. No guessing. No re-zero required.
Machined from solid aluminum with a matte anodized finish, this upgrade delivers premium feel, long-term durability, and smooth, confident grind adjustment.
Key Features
- Two-Piece Magnetic Coupling with Automatic Alignment: Instant magnetic separation for cleaning without unscrewing or disturbing your grind setting. Four identical alignment positions ensure perfectly consistent reattachment.
- High-Strength Neodymium Magnets with Near Zero-Backlash Fit: Powerful magnets deliver fast, secure decoupling and confident reattachment with zero wobble. High-tolerance mating surfaces create a tight, precise, premium feel.
- Solid Aluminum Construction: Machined from durable aluminum with a matte anodized finish and wear-resistant aluminum threads for long-term reliability.
- Large Knurled Grip for Precision Control: Oversized diameter and precision knurling provide excellent grip and smooth, accurate grind adjustments.
