The 3.5" Pro Series Mill is the largest, most advanced Flower Mill ever made. Engineered for professionals and enthusiasts alike, it delivers effortless milling at scale with unmatched smoothness, precision, and consistency. Every detail, from the deeper housing and ring to the new mill plate locking system was designed for people who demand more from their tools.

This is the mill you keep out on the table. The statement piece. The one built to handle serious volume while still maintaining the same effortless, airy, uniform results Flower Mill is known for.

Key Upgrades

Pro-Grade Capacity - A massive 3.5" footprint creates a wider milling surface, increased throughput, and smoother rotation under heavy load. Perfect for rollers, industry professionals, and high-flow environments.  Mill up 7g (recommended) at once and process more than 1000g per hour.   

Upgraded Locking Plate System - Quick-swap plates that lock tighter, stay aligned, and withstand repeated professional use. Built for reliability day after day.  

All New Pro Mill Plates - Thicker. Stronger. Built to last and stay in place.  Like our other mills the Pro Mill comes equipped with our #3 Medium Plate.  The #1 & #2 Plates now include chamfered bottoms to help with pass through and reduce clumping.  We are also introducing a Pro #6 Coarse XL Mill Plate which is great for pre-processing or rolling.

Customer Reviews (5.0 / 5 · 5 reviews)

Benjamin ★★★★★

Finally got the 3.5" Pro and the milling action is honestly a joy—even a full load goes through with that same smoothness they advertise, no wrestling or jamming. Handled a big prep session for a party without needing to stop and clean it once, which surprised me.

Isabella ★★★★★

The threads are butter-smooth right out of the box, and even a dense handful of herb mills down almost effortlessly with zero binding.

Natalie N. ★★★★★

Finally put this thing to work on a full ounce, and it chewed through everything without any binding or clogging. The milling action is so uniform I didn’t even have to pick out any stems afterward.
