COOL KNIGHT Electric Herb Grinder — 120g Large Capacity, Fast One-Button Grinding, Stainless Steel Blades

The COOL KNIGHT Electric Herb Grinder is a high-speed, one-button appliance that grinds up to 120g of herbs, spices, coffee beans or pollen in seconds while letting you choose coarse to fine textures by press-time.

This compact electric grinder combines a powerful motor, stainless-steel cutting blades and a visual lid switch to give reliable, controllable results for everyday kitchen and hobby use. Built for speed and convenience, it finishes coarse grinding in mere seconds and can refine to a finer texture with longer press times. The detachable cord and included cleaning brush make storage and maintenance straightforward.

How fast and how much can it grind at once?

The COOL KNIGHT grinder is engineered for volume and speed: it handles up to 120g in a single session and reaches full cutting speed in an instant. Typical coarse results take 3–5 seconds, while finer textures require 8–15 seconds of continuous press.

• Capacity: up to 120g per load
• Coarse finish: about 3–5 seconds
• Fine finish: about 8–15 seconds
• Runs at approximately 30,000 RPM for fast processing

What materials, motor and blade design are used?

The cutting system uses 304 stainless-steel blades for corrosion resistance and sharp, consistent cuts. A copper-wound motor provides durable torque while the blade geometry enables 360-degree grinding for even particle size.

• 304 stainless-steel cutting blades for strength and longevity
• Copper-wound motor for reliable performance
• 360° blade action for uniform grind
• High rotational speed to minimize processing time

How do safety features and controls work?

Operation is a single push-and-hold motion: the lid acts as the switch so the blades only run while the lid is pressed down, reducing accidental activation. The unit also includes automatic protection that cuts power for motor overheating or short circuits, and resumes only after cooling.

• Lid-integrated push-down switch for one-hand operation
• Variable grind control by press duration (coarse to fine)
• Automatic power-off for overload, short or lid-open conditions
• Cooldown recommendation: 15–20 minutes if thermal protection triggers

Is it easy to clean and store?

The grinder disassembles simply for cleaning and comes with a small brush to remove residue from the stainless-steel cup and blades. The power cord detaches for compact storage and convenient transport.

• Included cleaning brush for removing stuck particles
• Detachable power cord for tidy storage
• Smooth interior surfaces to simplify wiping and rinsing
• Designed for quick disassembly without special tools

Who is this for? The COOL KNIGHT Electric Herb Grinder is aimed at home cooks, small-batch coffee or spice enthusiasts, herbal hobbyists and anyone who needs fast, repeatable grinding with minimal effort. It’s ideal for people who value speed, volume and a simple one-handed control system, while also wanting a durable stainless-steel blade and safety features for everyday use.
