40mm Stainless Steel Conical Burrs

The burrs are 40 millimeters wide and made of stainless steel in a cone shape. This size balances speed and consistency for home use. The conical design reduces heat buildup during grinding, which helps preserve coffee flavor. Stainless steel resists corrosion and maintains sharpness over time. You get uniform grounds that improve extraction. This setup suits pour-over and drip users who want reliable results without the bulk of larger commercial grinders.
