Raw’s cone loader is a funnel-style tube that guides ground material directly into a cone. It is basic by design: no moving parts, no electric components.

Leira Cannagar Mold — Best for Specialty Packing
The Leira mold is designed for making cannagars, which are tightly packed cylindrical rolls. It uses a rod-and-mold system to compress material into a dense, even cylinder before wrapping. Not a standard cone filler, but useful for those who want a tighter, slower-burning format. The metal construction is durable. If you are experimenting with different formats beyond standard cones, the Leira mold is a specialty tool worth knowing about.

OTTO Electric Cone Filler by Banana Bros — Best Automatic Option
The OTTO grinder and cone filler is an all-in-one electric device that grinds and fills a cone in one step. Load the whole material in the top, place a king-size cone at the exit, and the unit handles grinding, sizing, and filling automatically. The fill is consistent and the process takes about 30 seconds per cone. The price is significantly higher than manual tools, but the convenience factor is real. A good fit for frequent users who want a streamlined experience.

How to Choose a Cone Filler
The right cone filler depends on how often you fill cones and in what quantity. For occasional single-use, a basic manual loader or funnel tool is sufficient. For daily use, a lever-action filler like the Crutch Box saves time and produces more consistent results. If you fill in batches, a vibrating tray model is worth the investment. Electric all-in-one options suit users who want the entire process simplified. Also check cone size compatibility before buying, as some fillers are designed for specific formats.

Frequently asked questions
What is a cone filler and how does it work?+
A cone filler is a device designed to pack ground material evenly into pre-rolled cone papers. Most manual versions use a funnel or tube to guide material into the cone, with a packing tool to tamp it down. Electric or vibrating versions use motion to settle the fill automatically for a more consistent result.
Can cone fillers work with different cone sizes?+
Many cone fillers are size-specific, designed for standard 1-1/4, king size, or 98mm cones. Some adjustable models accommodate multiple sizes. Always check compatibility before buying, especially if you use a specific cone brand or size regularly.
