Comparing Manual vs. Automatic Grommet Tools

Grommet tools might not be the first thing you think of when you are looking for additions to your sewing tool kit, but they make a big difference when it comes to adding strong, clean finishes to your projects. They make quick work of inserting grommets and eyelets into textiles, a process used to attach rope and other fasteners to all sorts of things, from shoes to porch awnings.

Designers, crafters, DIYers, and people working on large production products are just a few of the people who use a grommet tool. But like any sewing tool, grommet tools come in different varieties and knowing which one is best for you can make all the difference in your project.

What are Grommets and Grommet Tools?

A grommet is a metal or plastic insert that reinforces a hole to prevent the fabric from tearing. Grommets are used in many applications and are especially helpful in materials that are under tension. Shoelaces and outdoor banners are good examples of materials that are under tension. Without grommets, the fabric would tear and the item would be useless.

Much like their name suggests, grommet tools make it easier to insert grommets. A grommet consists of two parts: the washer and the eyelet or ring. The grommet tool clamps the two parts together into the material, creating a protected hole for cording. When used correctly, a grommet tool produces a reinforced hole that can withstand wear, tension, and even extreme conditions.

Manual vs. Automatic Grommet Tools

There are two types of grommet tools: manual and automatic. Both are useful, but one may be better suited for your project than the other. When comparing the two, consider:

Using a Manual Grommet Tool

A manual grommet tool is hand-operated and requires you to clamp down on the tool in a squeezing motion to set each individual grommet. It’s slow, but a manual grommet tool is good for small projects and low-volume work.

The components of a manual grommet tool are:

• A punching die that creates a hole in the textile
• A flat surface known as the “anvil” that supports the textile
• A pressing die that clamps the grommet in place

The first step to inserting a grommet with a manual tool is to prepare the fabric to make sure it’s smooth, clean and in the correct position. Mark the location for the grommet and use the punching die to create a hole. The hole should be slightly larger than the grommet to ensure a good fit. Align the die and press firmly to cut a hole in the fabric.

Next, place the eyelet part of the grommet into the hole from the front and align the washer from the back of the fabric. Use the pressing die to clamp the eyelet and washer together. When done correctly, the grommet will be securely fastened to the fabric with the hole in the center.

Troubleshooting a Manual Grommet Tool

If you’ve never used a manual grommet tool before, consider practicing once or twice on some scrap fabric. While the process is simple, a few things can go wrong.

For example, if the hole in the fabric is the wrong size, the grommet won’t fit securely. Also, applying uneven pressure to the tool when clamping can damage the grommet or prevent it from securing to the fabric.

Not supporting the fabric with the anvil can cause the material to tear or distort.

Using an Automatic Grommet Tool

An automatic grommet tool or machine is an electric power tool that does the same job as a manual tool but is much faster and more consistent. It’s great for manufacturing and high-volume use.

The components of an automatic tool are:

• An electric drive that performs the punching and clamping actions
• Multiple sizes of grommet dies
• Adjustable settings to control speed and pressure

The first step in using an automatic grommet tool is to turn the power on and make sure the machine is calibrated for the specific use. Next place the fabric in the feed tray and align the hole location and grommet die. With a simple press of a button, the tool punches a hole in the textile and inserts the grommet all in one smooth action.

As with any power tool, follow all safety guidelines when using an automatic grommet machine. First, wear protective gear, gloves and safety goggles. Double-check that the tool is calibrated and set up correctly to avoid accidents. Also, note that the clamping action of an automatic tool is fast and puts a lot of pressure on it. Keep hands and any other objects away from the moving parts when the tool is operating.

Troubleshooting a Manual Grommet Tool

An automatic tool requires some maintenance, cleaning after each use, and regular lubrication. Dies and other parts should be checked for damage and replaced when needed.

Even a well-maintained tool can malfunction sometimes. Jamming can occur if there is debris in the work field or the parts are not aligned properly. Also, uneven pressure can cause the grommet to be attached incorrectly. If this happens, adjust the tool’s pressure settings and check for worn or damaged parts.

Which Grommet Tool Is Right for You?

Both types of grommet tools have their advantages and disadvantages. When compared, crafters and others who only use grommets occasionally would probably be better off with a manual grommet tool. Manual tools are affordable, easy to store and work on many types of material.

Automatic tools are best for high-volume production. Professional designers, fabricators and manufacturers will benefit from the speed and convenience of a powered grommet tool. Automatic grommet machines are a good investment for the right applications.
