What to Consider When Choosing the Best Glass Cutter

Before you start shopping for a glass cutter, there are a few things you should know about them.

Size

Glass cutters range in size from 5 to 7 inches long. You need to pick a tool that fits comfortably in your hand so you can handle it deftly. If you have smaller hands, a large glass cutter may be hard for you to control. If you can’t control the tool, you might end up with bad cuts and wasted material.

Glass Type

The best glass cutter for you will depend on the type of glass you are cutting. Most glass cutters can handle a wide variety of glass types, but some work better for certain cuts than others.

Cutting thinner sheets of glass (under 6mm), like those used in stained glass art, doesn’t take much force to score the surface, so for that kind of precision work you’ll want a lighter tool you can use to make detailed scores.

Cutting thicker sheets of glass (up to 20mm), like those used for plate windows and mirrors,  rarely requires detailed cuts. Most of these score lines are straight and need a deeper score to snap accurately. In this case, you’ll want a heavier glass cutter you can bear down on to cut into the glass.

Some of the best glass cutters have swappable heads intended for specific uses.

Grip Type

There are several types of glass cutter grips.

  • Pencil-grip glass cutters are the most common style. They have long, thin handles that rest in your hand like a pencil. These are good for general use, and they include the traditional Fletcher-style, a tapered pencil-grip cutter with a brass ball on the end. This is the glass cutter preferred by many glass-work pros.
  • Custom-grip glass cutters also fit in your hand like a pencil, but they have an adjustable saddle you can place between your fingers or in the palm of your hand for extra leverage and control, allowing you to make detailed scores.
  • Pistol-grip glass cutters are good for beginners and those making quick cuts in thick sheets of glass. They have large handles contoured to fit the hand, and they allow you to use your arm strength to apply leverage to a sheet of glass instead of just your wrist.
  • Thomas-grip glass cutters are similar to custom grip glass cutters, but they’re short and fit in the palm of your hand. They have contoured rests you can hold between your thumb and index finger. They make detailed scores, but could be challenging if you have  larger hands.

Cutting Wheel

The best glass cutters have durable, sharp cutting wheels that make consistent, accurate scores. Most of the top models use tungsten carbide or steel alloy wheels for the job.

Tools with tungsten carbide wheels are the most durable and will produce the best results, and they are usually more expensive than tools with steel alloy cutting wheels. While cutters with steel alloy cutting wheels will be less expensive, they might not stay as sharp for as long as tungsten wheels. Dull cutting wheels lead to improper score lines, which could make glass snap inaccurately.

Some glass cutters have six-wheeled turrets with multiple cutting heads. Just rotate the turret to a new blade when the old one gets dull.

Cutting Range

Cutting range refers to the thickness of material a tool can cut. Be sure you pick the right glass cutter for the job at hand. To cut thin sheets of glass, you need a tool with a range of 2mm to 6mm. For medium glass thicknesses, you need a tool with a 6mm to 12mm range. There are also cutters that can cut thicker glass sheets with a range of 10mm to 20mm.

Many glass cutters have swappable cutting heads, so you can choose the cutting wheel you need and put it on the tool. Multi-head tools let you cut a wider range of glass thicknesses.

Self-Oiler

Lubrication makes glass cutting simpler. You’ll also need oil to ensure your cutting wheel remains sharp for as long as possible. Many of the best glass cutters feature self-oiling capabilities. These models have an oil reservoir in the handle, a wick that connects the reservoir to the wheel, and a compressible head. When the head compresses during a cut, the wheel comes in contact with the wick, allowing the oil to flow onto it.

Some models don’t self-oil, in which case you’ll need to oil the wheel while cutting.

Ergonomics

If you’re new to glass cutting, you might not realize how important ergonomics are. Applying pressure over a long score line can wear you out in a hurry. Choosing a glass cutter with the appropriate grip and size will make a big difference in your comfort level and the amount of control you have.

For beginners still building hand and wrist strength and endurance, a pistol-grip cutter may be the best choice. You’ll likely outgrow this cutter quickly as your hand gets stronger, but it’s a good starter cutter.

FAQs About Glass Cutters

If you still have some questions about your new glass cutter, we’ve got answers.

Q. How do I choose a glass cutter?

Choosing the best glass cutter mostly comes down to preference. However, if you’re new to glass cutting, you may want to choose a pistol-grip model to improve your leverage and wrist endurance.

Q. How do you use a glass cutter?

To use a glass cutter, drag the wheel from one edge of the glass sheet to the other edge, applying pressure while holding the cutter at roughly 45 degrees. Once you have an end-to-end score mark, lay the glass cutter underneath the sheet directly under the score mark, and slowly push down until the glass snaps at the seam.

Q. What kind of oil do you use to cut glass?

Almost any oil will do, including machine oil, but for best results, consider buying glass cutting-specific oil.

Q. How do I maintain a glass cutter?

Keep your glass cutter lubricated and clean. If the wheel wears out, replace the cutting head or buy a new wheel to install in your cutter. Dull wheels make bad cuts.

Q. How long does a glass cutter last?

A glass cutter can last a lifetime if properly maintained. Some manufacturers claim their cutting wheels can cut more than 20,000 meters of glass before they need to be replaced.
