Description

Our 4-Piece 2.5” Stainless Steel grinder is a favorite among our customers! After receiving so many positive reviews and experiences from our already proven 1.75” mini herb grinder, we wanted to create a larger version with the same quality and performance. This durable and sleek 4 part grinder is perfect for larger dosing and makes a positive impression on friends during a group sesh! Best Part? You can load more herb into the grinding chamber! 

The weight and feel of this big herb grinder is durable and heavy duty. Unlike aluminum grinders, it is constructed of 100% medical grade stainless steel, making it ideal for medical patients and anyone who has health concerns using aluminum products.  

This large grinder with a kief catcher is built with the same design methods and technology used in aerospace and renewable energy fields. It is high quality, guaranteed to perform and last a lifetime.

This 4 piece grinder features our Patent Pending labyrinth seal design. With our exclusive labyrinth seal solution, the top and middle pieces of the grinder are specially sealed together so your herb stays securely inside – no spills and no lost herb to worry about.

Create the perfect grind with just a few turns of the grinder. Sharp diamond-shaped teeth will cut and grind your herb with ease, and knurled top and bottom pieces save you from excessive wrist strain.

This four piece grinder includes a kief catcher or pollen catcher that functions as a storage compartment for collecting kief.

WHAT IS A KIEF SCREEN AND HOW DOES IT WORK?

A kief screen is a type of sift screen used to separate ground herbs from kief. An ultra fine stainless steel mesh screen allows the trichomes to pass through to the bottom chamber, while the bigger herb pieces remain in the catch chamber.

Our 4 piece grinder with a kief catcher features a sift screen and catch chamber on the bottom to collect those potent trichomes that fall off during the grinding process. The stainless steel sift screens are removable, allowing you to choose between fine and medium micron sizes. 

You can sprinkle these trichomes on top of a bowl, in a joint, or use it in cooking and baking your favorite meals and treats! 

The bottom chamber may double as a stash container for ready-to-go ground flower. Elevate your experience by upgrading to the best large 4 chamber grinder!

    2.5” 4pc., 1.75” 4pc.

    Published by Edward Lee on Sep 14th 2022

    I have used both the 2.5” 4pc as well as the 1.75” 4 piece grinders on a daily basis for over a year now. That are as perfect now as the day I bought them, with zero maintenance during that time. Contrary to some posts I read on the internet prior to buying, the labyrinth seal system does NOT clog up, even with heavy, sticky buds and no cleaning. These grinders are a rare example of form meeting function. They do the job perfectly, while the superb machine work demonstrates the pride involved in their manufacture. They go everywhere with me, and I still get pleasure every time I use either one! Thank you Iaso!

    Best grinder to date

    Published by Ollie on Aug 6th 2022

    I’ve used this grinder for about 3 months and I must say when I first went to buy the product I was a bit weary about paying the higher price but the quality of the metal , the grind quality and all in all the experience I get from it 11/10

    Functional and beautiful

    Published by Jeffrey on Aug 2nd 2022

    I think this is the best grinder ever made. This thing is an absolute work of art. I am obsessed with stainless steel so I bought one of the stainless storage containers, and a chillum too!

    Love the grinder

    Published by Jesse on Jul 10th 2022

    It's so much heavier than aluminum grinders and it feels great. The teeth are really sharp, be careful lol. My favorite feature is the double walled connection on the top chamber and how the teeth actually have space in between them to allow for the bud to be placed in. Expensive but worth every penny.

    Grinder

    Published by WILLIAM on Jul 3rd 2022

    This large grinder makes quick work of your herb. Top notch quality it is a solid build. I do however wish the catch bowl, below the grinder above the kief catcher, was just as deep as the small grinder. I love both grinder sizes, the small ones are perfect for my pipe to dip into for a bowl full. Thanks IASO

    Great Grinder

    Published by Michael on Jun 30th 2022

    This is definitely the best grinder I’ve owned. It is heavy duty and grinds material to the perfect fineness. Very expensive, but I can’t find a better product.

    Rolls-Royce of Grinders

    Published by Hector on Mar 23rd 2022

    By far the best grinder to date, I got this one because it's made from stainless steel, and not aluminum or copper. I also had Jamie and his team added custom logo on the top piece and it came out better than I imagined. I would highly recommend this product to my friends, and I have!
