Best Stained-Glass Grinders for Quality & Value: Product Review 

#1 Glastar Super Star I

If you’re just getting started or are a hobbyist-stained glassmaker, the Glastar Super Star II is one of the most well-equipped grinders on the market today. A quiet but reliable motor, an easy and useful cooling drain, and an accessory drawer for holding drill bits and accessories are among the features.

The engine in the Super Star II produces 19 ounces per inch of torque. As a result, we recommend it for those who are just getting started with stained glass work. It’s also suitable for hobbyists who don’t work on much more significant tasks than beginners. However, if you need to do any more challenging work now and then, the highest rpm it can reach is 3450, comparable to most experienced grinder motors.

Aside from that, there’s nothing on the Super Star II that indicates it’s targeted at the entry-level market. There is a cooling drain and a large drawer for storing tidbits, for example. The rubber splash protector is also included, a must-have when working, and allows for a much easier user experience while working with wet slices.

Despite being crafted for people who are just starting in craftsmanship, the Super Star II excels as a general-purpose weapon. It fulfills all of the requirements for a hobbyist grinder and then some. 


  • Good quality motor
  • High durability 
  • Best novice level-stained glass grinder
  • Rubber splash protector


  • Motor power could have been better 

#2 Glastar All Star G8

The Glastar All-Star G8, like the Super Star II before it, has excellent build quality and features that make it a good purchase. This is a perfect tool for any stained-glass maker, with 42 ounces per inch of torque and a glass mask to protect the eyes from getting spoiled while working, among many other features.

The All-Star G8 comes equipped with everything you might need or desire in a stained-glass grinder. The grinder has a torque of 42 ounces per inch and is aesthetically appealing. As a result, it is one of the most powerful machines available. As if it weren’t enough, it has a top speed of 3,560 rpm.

After discussing strength, we now turn our attention to the overall experience. The grinding work area, which measures 11″ by 13″ and is about a fifth larger than most of its immediate rivals, is spacious enough for any kind of work. 

The accessory drawer, as well as the glass shield to cover your eyes, are also welcome additions. It’s difficult not to recommend a computer as well equipped as the All-Star G8 because of the features and user interface. This commodity, however, has a higher price tag.

The All-Star G8 is the only alternative on this list that does not make any concessions in terms of features. Despite being a luxury product, it has such a stable working environment that it is difficult not to recommend it. This is an excellent stained-glass grinder.


  • Good user experience 
  • Power full motor
  • Top speed
  • High durability 


  • A bit expensive 

#3 Gryphon Convertible Grinder 

Gryphon is known for making goods that are one-of-a-kind in terms of design and features, and the Convertible is no different. It has a unique surface that can be twisted at any angle you like for grinding, as well as all of the other features you’d expect from a stained-glass grinder.

To begin, let’s address the elephant in the room: the incline workspace. It’s a great idea because it offers you a versatility level that’s unheard of in this industry. Furthermore, your neck and back pressure is reduced because you are not required to stand when grinding.

It also contains a glass cover that inclines with the workspace to shield the eyes when working. It comes with a 67 ounce per inch motor that can spin up to 3000 rpm if desired. If you need a second story surface for those more minor cuts, you can include that as an alternative.

Apart from the construction efficiency, there isn’t anything else to criticize about the Gryphon Convertible except the lower rpm (made of plastic). Despite its flaws, it is a one-of-a-kind addition to the stained-glass grinder industry. It is without a doubt one of the most ergonomically built grinders currently available.

The Gryphon Convertible is one of the most versatile and well-rounded grinders on the market today, with a genius build, a powerful engine, and a great work surface to match. Although the construction quality isn’t the best in the market, the features more than compensate.


  • Unique surface
  • Well-rounded grinder
  • Powerful engine
  • Good construction quality


  • Lacks a withdrawal 

#4 Power Max Deluxe II Grinder

Anyone looking for a mid-range-stained glass grinder would appreciate the Power Max Deluxe II. With almost every feature a stained-glass grinder could have, including a super powerful water-based cooling system and plenty of workspaces, this is one of the better balances between strength and features.

With an anti-seize lubricant, a working face protector, a foot pedal to control the pace as required, and three different bit sizes to ensure you get the correct width and shape of the grinding, and the Power Max Deluxe II is a great value.

The physical scale, which is smaller than other offerings and big enough for medium-sized ventures, is one of the compromises. The sluggish 2300 rpm pace is the further compromise, which can accommodate many projects but not all of them.

This makes it suitable for tasks ranging from novice to intermediate. You even get more accessories as usual than you can for a higher-end edition. Furthermore, the cooling mechanism is one of the stained-glass grinders’ exceptional features.

This one comes with trade-offs, but they favor ease over firepower. This is one of the finest all-around grinders available, with a lengthy list of features and enough strength to grind most stained-glass parts to perfection. In boxing terminology, it is the middleweight champion.


  • All-around grinder
  • Anti-seize lubricant
  • Working face protector
  • Foot pedal


  • Low power 

#5 Gryphon Gryphette

The Gryphon Gryphette is another excellent commodity from Gryphon, with a great price and various features. It’s a lightweight, durable grinder that’s perfect for students and aspiring artists since it takes up little room while having strong grinding capabilities thanks to its 0.67-amp motor.

This tiny stained-glass grinder is suitable for anyone searching for a low-cost but practical grinder. It has a 3000-rpm motor on less than 7 inches by 7 inches square floor, which is ideal for a dorm room that is already cramped.

Many other experienced grinders have a plethora of good features but come at an expense. This piece is perfect for those who wish to master stained glass grinding craft but don’t want to waste hundreds of dollars doing so. It’s a refreshing improvement to get a grinder that does the job at a lower price.

This is a total break from anything else; it just does one thing, but it does it very well. With this, you won’t feel the need for another grinder. While several sacrifices must be made, the most critical point remains. Using a well-functioning stained-glass grinder shouldn’t cost hundreds of dollars.

Aspects to Consider Before Buying Best Stained-Glass Grinder

When purchasing a stained-glass grinder, there are many significant considerations to evaluate and evaluate to choose the best-performing and highest-quality-stained glass grinder. The grinder you buy should be well worth the money and capable of doing the job.

RPM and Torque 

The number of rotations per minute (rpm) that the grinder’s motor rotates is the first thing to remember. This usually falls between 2,800 and 3,600 revolutions per minute. A faster rpm produces a cleaner finish on the glass sides to use a faster engine.

The torque number is another equally relevant factor. It shows how strong a motor is in terms of how much speed it can maintain and how quickly it can reach that speed. 

For stained glass hobbyists, about 20 ounces per inch of torque is optimal, which is ideal for beginners. For most consumer-grade ventures, a torque of 20 to 35 ounces per inch is needed. A figure of over 40 ounces per inch gives you peace of mind that the machines would not be drained of fuel, regardless of the scale of the job.


Most grinders nowadays come with various extra attachments that can be purchased separately or combined with the unit. These allow consumers to improve their devices’ efficiency and, in the long run, reduce the likelihood of having to upgrade them.

Multiple parts, foot pedals, sponge/s, anti-seize lubricant, and other attachments can be included with some grinders. However, some products, such as eye safety, lack the requisite functionality. As a consequence, it’s a brilliant idea to find out what’s used first.

Surface Area

Its height largely determines the amount of work surface area provided by a stained-glass grinder. The more surface area you have to deal with, the bigger the unit. Users who constantly grind more extensive materials may want to invest in a system with a wide surface area.

Larger grinders are more expensive and more difficult to store and ship. A smaller stained-glass grinder will suffice if you do not wish to work on more significant tasks. Some grinders have several working surfaces, either included with the device or purchased separately. This gives consumers more options when it comes to the types of materials they can deal with.


How to Use A Stainless Glass Grinder? 

Until you grind the bottle, make the required cuts. The devices are designed for smoothing edges and grinding curves that are otherwise difficult to cut. It’s crucial to use the right level of pressure. Chipping can occur if you push too hard. When so much force is applied to the grinder, the rotation speed slows down; use this as an alarm signal.

Protection Is Important 

When grinding, small pieces fly, so eye safety is essential. Many grinders have a face mask, and some also have a magnifying glass. You should wear goggles if facial safety isn’t included in the kit. They may, though, be inconvenient and obstruct good vision.

Glass may be prevented from expanding across the room to any degree by placing a rough mat under the working table. A splash guard should be used to prevent the water from splashing anywhere. When you’re not using it, remember to turn it off. When no one is present, don’t keep it going.

Adjust and Replace Your Diamond Bits 

By setting the height of the pieces to the most appropriate location at the start, you can use a glass of various thicknesses without having to fiddle with them. You will lower the height of the bit later as it begins to wear. You are not required to substitute the bit as soon as you feel the need to click harder. To use a specific section of the bit’s surface, make small vertical changes.

It’s time to get a replacement because going up or down doesn’t make a difference. Special parts make adding multiple effects to the edges much smoother. You can also drill holes in some of them.

How to Maintain A Stainless Glass Grinder? 

After each use and any time, you replace a piece, lubricate the shaft with anti-seize lubricant. The lubricant stops the bit from seizing to the shaft, as the name implies. For every 4 hours of working time, adjust the water and empty the tank of glass fragments.

If your system works with a sponge, make sure it’s damp before you begin. When operating, search to see if the reservoir is full. A grinding coolant with water is used daily to increase the life of the grinding head. It’s a good idea to regularly check the bit for wear and other defects, particularly after a lot of use.

Take Care of Your Bits

The consistency of the workpiece is highly influenced by the bit used. Using a coarse-grit bit on the fragile glass will quickly chip it. The components you deal with are better suited to fine or ultra-fine pieces.


Create a repair plan based on the machine’s manufacturer’s recommendations and how much you use it. This makes the protocols much easier to execute and helps you keep track of any repair activities that have gone unnoticed.

I Replaced the Head, And It Still Causes Chipping. What Should I Do? 

New heads may cause chipping. To solve this dilemma, start with some scrap glass. The head will be fine-tuned as a result of this. A brick or a dressing stone may also be used.


There are many grinders on the market. Each one acts in a slightly different manner from the others. However, with too many choices to choose from, a buyer can find it challenging to make a decision. With that in mind, we’ve compiled a list of fantastic items that we believe can be used in various scenarios.

We have outlined the features in the right stained-glass grinder based on your preferences, in addition to the feedback and suggestions. Hopefully, you’ll find one that will last and do you well for many years.
