Metal Grinders

Metal Grinders | Professional Precision & Lifelong Durability

When you want a consistent, fluffy grind every single time, metal is the gold standard. At R420.ie, we stock the largest selection of metal herb grinders in Ireland, built from high-grade materials like aircraft-grade aluminium and zinc alloy. These grinders are designed to shred through even the densest herbs with ease, ensuring an even burn and maximum flavour for your session.

The R420 Signature Metal Grinder

We’ve designed our own range of R420 Supplies grinders to offer premium performance without the premium price tag. Built with a sleek matte finish and our logo on top, these are a staple of the Irish scene.

Two Essential Sizes: * 50mm (Medium): The perfect "everyday" size that fits comfortably in your pocket or a small stash bag.
- 60mm (Large): For those who need more leverage and the capacity to grind larger amounts at once.
4-Piece Efficiency: Both sizes feature a 4-part design, including a dedicated grinding chamber, a fine-mesh kief screen, and a bottom collection tray to save your most potent material.
Diamond-Cut Teeth: Precision-engineered teeth that "shred" rather than "crush," preserving the integrity of your herbs.

RAW x Hammercraft: The Connoisseur’s Choice

For those who want the absolute best, we are proud to stock the RAW x Hammercraft Aluminium Grinders. This collaboration brings together the world's favourite paper brand with Hammercraft’s legendary engineering.

Aircraft-Grade Aluminium: These are incredibly lightweight yet nearly indestructible.
Superior Grip: The "Hammercraft" textured finish ensures you have total control, even if your hands are sticky.
Premium Colours: Available in classic Black, bold Red, and the vibrant Rasta tri-colour.
Extra Smooth: Featuring a friction ring that prevents "metal-on-metal" grinding, making the rotation feel like butter.
