Glass Grinder For Accurate Shapes

Best Stained Glass Grinder 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! Did you know there are many other creative things you can do with a stained glass grinder, for example drilling holes 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 bevelling
  • the availability of replacement bits

Compatibility with other manufacturers’ products is also worth thinking about. You may want to benefit from specialist stained glass grinder accessories such as drilling bits and ripple bits for textured glass.

Best Stained Glass Grinders

Glastar All Star G8 Grinder – Recommended
glastar glass grinder
The 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.
Pros

  • 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 stained glass grinder feels very safe and stable.
  • 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.
  • handy drawer for accessories, along with a coolant drain. If you’re like me and are always losing your stained glass 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.

Cons

  • 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 stained glass 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.

Is Grinding Glass Necessary?

The short answer is no, you don’t have to grind glass.

You don’t have to grind glass edges to make copper foil stick. If you don’t believe me, try this test. Cut a glass shape without grinding. Now try sticking copper foil around the edges. Did it stick? I thought so!

I’m not sure why the myth of having to grind each and every piece of glass has come from. I DO know that it will waste a lot of your time.

A stained glass grinder should only be used to tidy up a piece of glass and get it to fit accurately.

Other Stained Glass Grinders

Inland Wizling Cg

wizling stained glass grinder

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.

You can see it on Amazon HERE:

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.

3 Methods For Cutting Glass Shapes

16 thoughts on “Glass Grinder For Accurate Shapes”

  1. Completely disagree with you!!! You need to grind glass to have a nice finished product. Sure you can cut glass to fit but for nice smooth edges, you need to grind. It is not easy to foil glass that is rough and sharp. I was in business for 22 years. I made everything from small hummingbirds to large, 1000 piece molded lampshades to lots of commissioned pieces. A grinder is a necessity for a professional art piece. Don’t skimp on your stained glass finished pieces. The money you spend on a grinder is not wasted!

    • Oh good, I love it when people find a way they’re happy with and stick to it Kathleen 🙂 I grind glass in certain situations too and would never dissuade anyone from getting one.
      I like to put forward different options so that people can choose which works best for them. I personally mix and match; I’m always very happy if I cut accurately first time and don’t have to spend time grinding the glass.
      Thanks for your thoughts.

  2. Can you recommend a tool for polishing the edges of cut glass such as wine bottles, so they are not sharp? Is there a bit I can use on a grinder that will do this? Thank you in advance for your help.

    Reply
    • The finer the grit the smoother the edge you’ll get but you won’t get a shiny polish unless you use hand pads and fine grit, taking it down slowly through the grits until the surface is smooth. Hard work! If you only want ‘safe’ and not shiny, I use diamond hand pads (affiliate) like these to make edges safe. I hope that helps.

  3. Of course you don’t need to grind the glass to make the foil stick. If that were true it would not stick to the non-ground surface of the glass. But if you use a foiling machine or even tend to put your foil on tight by hand, you will find yourself with many torn foil corners and edges to repair, and probably more band-aids on your sliced fingers. If you are not going to grind (which I agree with) use a hand held grinding pad to take off those knife edges that happen and soften the corners.

    • I’m with you on this one Karen. There isn’t any need for grinding to make the foil stick, only to get the glass to fit. Make each shape safe to handle with a grinding stone.
      Thanks for taking the time to comment.

    • It looks like this has been discontinued Erik. Your best best would be eBay or somewhere similar where someone is selling old stock.
