COOL KNIGHT Electric Herb Grinder — 120g Capacity, 30,000 RPM Motor, One-Button Lid Control

The COOL KNIGHT Electric Herb Grinder quickly grinds up to 120g of herbs, spices, coffee beans and more with one-button, lid-activated control for coarse to fine results.

Whether you need a fast, large-capacity grinder for the kitchen, countertops or small-batch preparations, this compact electric model combines a 120g bowl, a 30,000 RPM motor and 304 stainless-steel blades to shorten grinding time and simplify texture control. The lid acts as the switch, so a gentle press starts the blades and releasing the lid stops them—letting you choose coarse, medium or fine in seconds. Built-in safety cutoffs, a detachable power cord and a cleaning brush make it practical for everyday use.

How fast and how much can the grinder handle?

This COOL KNIGHT unit is designed for speed and volume. It can process up to 120 grams of herbs or spices in a single session and reaches full grinding power in seconds thanks to its high-speed motor.

• Capacity: holds 120 g per batch for fewer refills.
• Speed: motor spins up to 30,000 RPM for rapid results.
• Time to grind: coarse in about 3–5 seconds; fine in about 8–15 seconds.

Can I control the grind size easily?

Yes — the lid is the control. Press and hold the lid to run the blades and release when you reach the desired consistency; a short press yields coarser pieces while a longer press produces a finer texture. The transparent lid lets you watch the progress without interrupting the process.

• Visual lid: view the texture while grinding.
• One-handed control: press-and-hold to vary coarseness.
• Stop-on-release: blades only run while the lid is pressed down.

What materials and safety features does it include?

The grinder uses durable, food-safe components and several built-in protections. Blades are 304 stainless steel and the motor windings use copper for longevity; the unit also has automatic cutoffs for overheating, motor faults and when the lid isn’t correctly engaged.

• Blades: 304 stainless-steel, shaped for 360° grinding.
• Motor: copper-wound design for durability and high speed.
• Safety: automatic power-off for overheating, short circuit or open lid.

How easy is it to clean and store?

Maintenance and storage are straightforward: the power cord detaches for compact storage and a small brush is included to clean the stainless-steel bowl and blade area. For safety, let the motor cool if the thermal protection has tripped before cleaning.

• Included brush: removes residue from blades and chamber.
• Detachable cord: stores separately to save space.
• Simple disassembly: lid lifts off so you can access the bowl safely.

Who is this for: The COOL KNIGHT Electric Herb Grinder is ideal for home cooks, small-batch spice blenders, coffee enthusiasts and anyone who needs a fast, reliable way to grind up to 120 g at once. It suits users who value one-handed operation, visible grind control and built-in safety features, and it’s especially useful where repeated, quick grinding tasks would otherwise be time-consuming.
