4 Piece Grinders

Wholesale 4-Piece Grinders | Custom Branded Grinders for Dispensaries

The 4-piece grinder is the core of any cannabis accessories program. It's what customers expect to find, what they ask for by name, and what they'll use daily for years. If you're building a branded accessories line or stocking a dispensary's accessory wall, this is the right place to start.

We carry the full range: durable aluminum grinders, solid zinc grinders, modern matte-coated grinders, natural wood grinders, heavy-duty stainless steel, and push-button electric grinders. Available in 40mm, 55mm, and 63mm with full custom branding.

Why the 4-Piece Is the Right Anchor Product

• Four chambers in one: grinding, collection, storage, and kief catching. Most complete functionality in a single tool.
• Consistently the most-requested grinder style — customers actively seek it out.
• Multiple features justify a higher retail price than simpler grinder styles.
• Used multiple times a day, which means more impressions on your logo over the product's lifetime.

Collection by Material

Aluminum Grinders

The bestselling option across the board. Lightweight, rust-proof anodized aluminum with a good balance of price and durability. A clean canvas for laser engraving. Often available with no minimum order quantity.

Zinc Grinders

Noticeably heavier and denser than aluminum. Customers who pick one up feel the difference. A natural step-up product if you want a higher price point in the lineup.

Matte-Coated Grinders

Fingerprint-resistant finish with a high-adhesion surface that takes full-color UV printing well. Go with these if your logo has multiple colors or detailed artwork.

Wood Grinders

Real sustainable wood exterior with a metal grinding chamber inside. Laser engraving burns your logo directly into the wood — a good fit for organic or earth-brand aesthetics.

Stainless Steel Grinders

The heaviest and most durable option we carry. Clinical-grade stainless, built to last indefinitely. Good for luxury or premium positioning at the top of your product line.

Size Guide

• 40mm: Travel and pocket size. Lower price point, good entry-level option.
• 55mm: Most popular size. Good balance of capacity and portability — sells across all customer types.
• 63mm: Home grinder. Larger capacity for regular users and a natural upsell from the 55mm.

Branding Options

• Laser engraving: Works on aluminum, zinc, stainless steel, and wood. Permanent, one-color mark etched into the surface. Won't peel or fade.
• Full-color UV printing: Best on matte-coated grinders. Supports multi-color logos and detailed artwork.

Frequently Asked Questions

What's the MOQ?
Aluminum grinders often have no minimum for laser engraving. Zinc, matte, and printed grinders typically start at 100 units. Specialty materials may require more.

How does a 4-piece grinder work?
Four chambers: lid with teeth, grinding chamber with teeth, collection chamber with mesh screen, and bottom kief catcher. Herb gets ground, falls through to the collection chamber, and fine particles filter down through the screen into the kief catcher.

What's the turnaround time?
Laser-engraved items often ship within 1–3 business days. Bulk printed orders are typically 3–5 weeks after design approval.

Which size should I stock?
55mm is the most consistent bestseller. Add 63mm as an upsell and 40mm for travel-minded or budget-conscious customers.

Aluminum vs zinc vs stainless?
Aluminum is your core product — affordable, versatile, reliable. Zinc adds weight and a more substantial feel at a mid-range price. Stainless is the top-shelf option for customers who want something built to last.
