Plastic Grinders

Plastic Grinders | Hemp, Medical-Grade & Portable Shredders

Don't underestimate the power of plastic. At R420.ie, we stock the largest selection of plastic grinders in Ireland, proving that you don't need a heavy metal tool to get a professional, fluffy grind. From eco-conscious hemp-based shredders to German-engineered medical plastics, our collection is perfect for the smoker on the go who values portability and ease of use.

The R420 Custom Plastic Range

We’ve developed our own line of R420 Supplies plastic grinders to provide a reliable, budget-friendly option that doesn't compromise on performance.

The 2-Piece Classic (60mm): Simple, effective, and available in various colours like red, black, and clear. It features a built-in storage compartment in the lid and a magnetic closure to keep your herbs secure.
The 4-Piece System (60mm): For those who want more. This model includes a dedicated storage section and a fine screen, allowing you to filter and save kief—a rare feature in a plastic grinder at this price point.
Diamond-Cut Teeth: Every R420 plastic grinder is equipped with precision-moulded "diamond" teeth that stay sharp enough to chew through the densest herbs.

Eco-Friendly Innovation: Biodegradable Hemp

As Ireland’s leading smoke shop, we are proud to offer sustainable alternatives to traditional petroleum-based plastics.

R420 & Santa Cruz Hemp Shredders: Made from 100% natural, biodegradable hemp biocomposite. These are incredibly durable (often outlasting cheap metal grinders) and are carbon-neutral.
Natural Texture: The hemp material provides a superior, non-slip grip—perfect if your hands are a bit sticky or if you suffer from wrist discomfort.
Compostable: If you ever decide to upgrade, these grinders won't sit in a landfill for centuries; they are designed to break down naturally.

Medical-Grade Precision: Storz & Bickel

For the health-conscious or those using vaporisers, we stock the iconic Storz & Bickel Herb Mill.

The Herb Mill XL (90mm): This legendary German-engineered grinder is a favourite for a reason. Made from food-safe, medical-grade plastic, its extra-large diameter and razor-sharp "shark teeth" produce a uniquely fine, uniform grind that is essential for top-tier vaporisation.
Transparent Design: The clear orange plastic allows you to see exactly when your herbs have reached the perfect consistency.
