Why do you need a stained-glass grinder?

6 Best Stained-Glass Grinders For Perfect Results

If you are just starting out in the stained glass artistry, a beginner-friendly model like the Glastar SuperStar II Grinder is an excellent choice and will allow you to easily learn. If you consider yourself a hobbyist and are well-experienced in work, something in a professional realm may work better, perhaps the Inland Craft Wizard IV Stained Glass Grinder. Either way, a stained-glass grinder will provide you with the tools and equipment needed to begin creating beautiful stained-glass art in an efficient way.

Features to consider before you buy a stained-glass grinder

Buying a stained-glass grinder can be somewhat daunting due to the various features they each provide. With work surface, grinding bits, motor, size, etc. all taken into consideration, there are a plethora of options on the market.

Work surface

The work surface of your stained-glass grinder is also known as the “table,” and it is the flat surface that you lay your glass on while you work on the edges. If you are working on larger stained-glass projects with large pieces of glass, it would be best to look for a grinder with a larger area to work with. The Gryphon Convertible Professional Stained Glass Grinder has a large work surface of 13.5 x 10.5 inches, which is plenty of space to work with large bits of glass.

Sometimes, having a larger space, even if your glass pieces are small, is just more comfortable and convenient.


Grinding bits

Grinding bits are the small pieces of your grinder that help refine edges and shave down pieces of glass. For any generic grinding machine, the size and shape of your grinder will directly correlate to what kind of grinding bit you need. Most grinders come with a couple grinding bit that fits over the motor, and these are typically 1″. Smaller grinder bits, around 1/8 inches, are used for tight curves and edges, and drilling holes in the glass. The Glastar All Star G8 Grinder comes with a 1” and 1/4” grinding bit. The different sizes of grinding bits will tell you what kind of cut you’ll get on your glass.

A stained-glass grinder’s motor is what decides if the grinder is powerful or not. Grinder’s with high RPM’s offer flawless grinding experiences, even if the grinder itself is quite small. RPM stands for rotations per minute, which tells you how fast the motor is running.

Typically, motors range from 2,900 to 4,500 RPM. With a faster RPM, your motor will run quickly and perform more efficiently.


Quick RPM speeds ensure that the edge of the glass remains smooth for more precise flow. The YaeTek Power Stained Grinder has an RPM of 4200, which means high quality, high power, and efficient speeds. High RPM’s are necessary if you’re looking to get your projects done quickly, as the speed of the grinder is increased with higher RPM’s.


The size of the overall stained-glass grinder is relevant if you are someone who plans on traveling with your grinder, has a limited workspace, or simply doesn’t want the hassle of a large machine. For many, a large workspace is needed and preferred to fit their stained-glass grinder in. For others, a small, portable grinder is desired. Smaller sizes don’t always equal less power; take the Glastar SuperStar II Grinder, for example, with a surface size of 8 x 9, it still performs exceptionally well without taking up a large amount of space. Some people find it convenient to keep their grinders in large sinks, so consider where you’ll be storing yours when choosing between sizes.


Weight is an important factor in searching for a grinder if you were hoping to have a portable grinder. If you have one workspace and keep your grinder there at all times, weight may not be a factor for you.

If you want an easily moveable grinder, consider how the weight of the grinder could impact your ability to do that.


Lighter weighed grinders like the Inland Wiz CG Stained Glass Grinder, at 9 pounds, are much easier to transport from workspace to workspace. The cleaning process also requires you to lift your grinder, or at least move it around, so keep that in mind when weighing your options.


6 Best Stained-Glass Grinders For Perfect Results

Mostly all stained-glass grinders come with two accessories, and those are the bit options. However, a stained-glass grinder requires much more than just the bits. A plethora of other accessories is needed and available when purchasing a high-quality grinder. Some grinders, like the Glastar All Star G8 Grinder, come with built-in accessory drawers for maximum convenience. Other accessories would include extra grinder bits and precautionary accessories like more than one work surface and built-in face shields. Some grinders come with all of the necessary accessories, but most of these can also be found at any craft store.


Stained glass grinders are heavy machines that can break if not properly taken care of. This is why most stained-glass grinders come with a warranty, typically one that is five years. This simply means the issuer of the purchase promises to repair or replace the machine if necessary. This is an important factor to look when buying your grinder, as the machines are not bulletproof and can break if something goes wrong. The Inland Craft Wizard IV Stained Glass Grinder is one of the grinders listed above that comes with a five-year warranty. Because these grinders are large, heavy, and electrical, some mistakes are inevitable. A warranty will have you back when the worst happens.


Before using your grinder, remember that safety always comes first. A stained-glass grinder is a heavy-duty electric machine, so be wary of any electrical safety hazards. To help minimize the possibility of danger, keep your studio or surrounding area tidy and make sure to clean up after each use. Wear eye goggles or use a protective face shield to keep small bits of glass from coming in contact with your eyes. Don’t forget how close your fingers are too small bits of glass and the grinding head, and try to avoid picking up glass bits with your bare hands. Finger guards are never a bad idea, and they can be purchased at almost every craft store.

Stained glass grinders need optimal care and cleaning to make sure the machine stays running smoothly. To clean, the water reservoir should be drained after every use. To avoid unpleasant smells and for overall health reasons, it’s best not to keep water in the reservoir. If your grinder uses a        sponge, clean it out to avoid it from becoming hard and useless. The extra glass that as accumulated should be discarded into a wastebasket, not into a sink. Glass grit is thick and become clogged in your pipes. It is also important to clean any eye or face shields after each use with running water and avoid rubbing it to ensure to scratches appear.
