“The Grinder” is the latest and greatest in glass grinder technology. It has excellent features and is certainly nice to use! We have one we utilize for commission projects and wish we had more. 

That said, the latest and greatest is not a requirement! The Gryphette grinder we use in classes is a less expensive option that gets the job done all the same.

Most grinders last a lifetime. So it’s worth getting a product you enjoy using!


Powerful, Whisper Operation 

THE GRINDER’s super quiet, powerful motor boasts a torque of 57 oz/in (0.4 N/m) at 4500 RPM, surpassing any model available. Vibration dampening technology absorbs shock and provides added stability to maintain an extremely quiet whisper operation for the most pleasurable grinding.

Tremendous Surface Area

THE GRINDER is designed with a spacious 12″ x 16″ (30 x 40 cm) surface.

Universal Compatibility

THE GRINDER is equipped with a 5 ft. (1.5 m) durable and removable 3-prong cord which meets international standards and is 110-220 VAC compatible.

Mini G Elevated Work Surface

The secondary platform with water reservoir can be effortlessly placed atop the main grid enabling use of 1/4″ and 1/8″ spindle top bits. Spindle top bits are sold separately. Equipped with its own reservoir, the secondary platform has water ingeniously delivered to the grinding head for flawless execution.

Platform Dimensions: 1.3”H x 6”W x 5”D (33 x 153 x 127 cm)

Elevated surface outfitted with EZ-Lift Grid that can be removed for the addition of water or cleaning with specially-designed cutouts

Platform is self-sufficient with its own, separate water supply

The reservoir water level can be continuously monitored through the EZ-View Windows.


The Guard is a wear resistant splash curtain designed to keep the work surface clean and dry. It is manufactured from 100% BPA free, wear resistant, flexible soft silicone material. Glass pieces of unlimited size and length can easily slide through the bristles which capture debris and water returning to the reservoir.

Removable Water Tray

Unlike other grinders, the water reservoir comes equipped with a removable tray which can be easily emptied after use. With handles on each side, the lift-out tray makes cleanup simple and safe. Eliminate carrying a heavy awkward grinder to the sink or potentially spilling its contents on floors and work surfaces. Any accumulated glass grit can be cleaned out with the included scraper and disposed of or repurposed.

Water Wave Stabilizer Design & Support System

The uniquely designed main grid has incorporated supports and baffles on the underside to stabilize the work surface, limiting water movement during tray transport.

Universal Compatibility

THE GRINDER is equipped with a 5 ft. (1.5 m) durable and removable 3-prong cord which meets international standards and is 110-220 VAC compatible.

Accessory Drawer

The exclusive, compartmentalized and built-in drawer is a space saving way to store spare bits, included scraper, Aqua Flow System® replacement brushes, stainless steel bit guard, and other tools!

Everwear Bit Guard

Made from durable stainless steel, the bit guard allows interchangeable usage of 3/4″ and 1″ grinding bit sizes.

EZ-Guide Channels

The GRINDER is equipped with convenient channels located on each side of the working surface for attaching tools.

The Aqua Flow System

Artists won’t realize the short comings of a conventional sponge until they’ve experienced the ingenuity of a highly engineered water system included with THE GRINDER. To replace ineffective sponges and enhance glass grinding, two Aqua Flow Systems® and three brushes are included for both main and elevated work surfaces.

EZ-View Windows & Lift Grid

It’s important to keep a sufficient flow of water to your bit head while grinding. Reservoir water level can be continuously monitored through the EZ-View Windows. The Lift Grid easily removes for the addition of water or cleaning with the smartly-designed cutouts.

Included With the Grinder

1-in. Quick Fit Bit System. No Keys Required. Reusable Holder.

Easy to use & Time Saving

No need to find and use keys or locking tools – no grinder freeze-ups – no frustration! Changing bits is simple and fast, even for individuals with reduced grip strength.

Durable and Corrosion Free

High-impact polymers extend the life of the Quick-Fit Bit Holder and eliminate the possibility of corrosion  and freeze-ups on the grinder shaft.

Ultra-Smooth Grind

Engineered with industrial elastomer, the Quick-Fit Bit Holder absorbs grinding vibration and protects glass from fracturing, chipping or shelled edges.

Long-Lasting Grind

Layers of high-quality diamond particles give the Quick-Fit Bit a long-lasting, ever-sharp grind. 100% Utilization

The Quick-Fit Bit Holder may be adjusted vertically on the grinder shaft, the bit may be reversed to utilize the full glass grinding surface.


Continuous Water Flow

The patented Aqua Flow System brush bristles transfer water from the reservoir to grinding bit heads via capillary action, requiring addition of water only at the onset of grinding.

Prevents Dry-Out

With conventional sponges, water needs to be added every 10-15 minutes. With the Aqua Flow System, the bristles do not absorb sludge or dry-out, eliminating the need for constant cleaning, adjusting and rehydration.

Prolongs Bit Life

The proprietary anti-clog brush bristles allow water to flow continuously, while cleaning the bit head. This feature maximizes the life of grinding bits, ultimately saving you money on replacements.

Anti-Clog Technology

The Aqua Flow System’s anti-clog technology allows water to flow continuously, drawing sludge away from the grinding bit back to the reservoir.
