Glass Grinders

Best For Quality And Value

The stained glass grinder will soon become your best friend although strictly speaking it is not essential for making stained glass.
Once you have one you'll wonder how you did without! There are also many other creative things you can do with a grinder, for example drilling and bevelling.

The main things to consider when thinking of buying a grinder are:

  • size
  • power (or torque)
  • whether it can easily be adapted for drilling or beveling
  • the availabity of replacement bits

Compatibility with other manufacturers’ products is also worth thinking about as you may want to benefit from their specialist accessories.

Best Stained Glass Grinders


Glastar All Star G8 Grinder

glastar glass grinderThe Glastar All Star G8 Grinder is the Rolls Royce of the grinder world. Efficient and reliable, it has that quality feel about it that you only get with the best.

It lives up to its promise by being sturdy and long-lasting. I've had mine for years and have had no trouble with it.

Despite having lots of useful extras, it's light, easy to assemble and to clean.


- one of the quickest and most powerful grinders, running at 3560 rpm with a 1/9 hp motor. This means it eats away glass faster than other grinders. No more sore fingers!

- boasts a very generous 11” X 13” work surface which is great for bigger projects. The larger area means that the grinder feels very safe and stable.

- handy drawer for accessories, along with a coolant drain. If you're like me and are always losing your grinder accessories, this is a very helpful feature.

- protective shield which helps stop the glass and water from spraying everywhere. I always wear safety glasses when grinding to be on the safe side but it does form a useful secondary barrier and stops you getting wet.

- compatible with virtually all the accessory products available, which makes it a very valuable and adaptable part of any stained glass kit. You can drill through fused glass easily with the drill bit.


- spare drill bits are a little expensive, although it comes with two grinder bits – 1” and ¼”, which should cover most projects.

- the built-in water pump is great for keeping the glass cool, but is a bit splashy.


The Glastar All Star G8 Grinder is a quality grinder that came top in the reviews. It's reliable and built to a professional standard and will suit stained glass makers at any level. 9 out of 10.

Other Stained Glass Grinders

Inland Wizling Cg

Inland make a whole range of grinders. The Wizling Cg is their most basic model. It's cheap and reliable and lasts.

It is incredibly simple to set up and operate and never breaks down.

You can use Vaseline for lubricating the shaft and inside the grinding bit to prevent it getting stuck.


- It has a reasonably sized 9” X 10” grinding surface, which adequately supports bigger pieces of glass as you pass them across the grinding bit.

- With a 3450 rpm motor and 1/22 hp, it isn’t the most powerful, so if speed and power are what you need for heavily textured glass, or if you do lots of grinding this might be too slow and hard for you.


This is a cheap and cheerful grinder which is certainly up to most tasks. It is more than adequate if you can't find the extra dollars for the Glastar and will serve you very well. 8 out of 10.

Inland Wiz Cg Grinder

The Wiz Cg Grinder is a mid-range grinder.

With a 3550 rpm motor and 1/11 hp, this has more power and speed than the Wizling Cg and is a good bet for copper foilers who use their grinder more regularly.

- It comes with two grinding bits which is a plus, a standard ¾” and a smaller ¼” for more fiddly work.

- Both of these Inland grinders come with a 5-year warranty.

- You can also convert these Inland glass grinders for drilling by buying an adaptor and a diamond drill bit – they come in 3/8”, 1/8” and 1/4”, depending on the size of hole you need.


A very good all-round reliable grinder. Reasonably quick and powerful, but I'm not sure if it warrants the extra price-tag over the Wizling Cg. I'd rather spend the extra and go up market to the Glastar. 6.5 out of 10.
