When it comes to hand tools, the quality, durability, and functionality are critical factors to consider. Channellock, a brand known for its high-quality tools, offers the GLS-3 Tongue and Groove Plier Set, a trio of pliers that promises the same commitment to excellence. This review will delve into the features, benefits, and potential drawbacks of this set.

Key Features and Specifications

The Channellock GLS-3 set consists of three pieces: the 426 - 6.5-inch, 420 - 9.5-inch, and 440 - 12-inch pliers. All three tools are made with high-carbon C1080 steel for superior performance and longevity.

Each plier features a patented PermaLock fastener, which eliminates nut and bolt failure, enhancing the tool's durability and lifespan. Besides, the tools have been coated with a special rust-preventative substance to resist corrosion.

The pliers also feature Channellock's unique tongue and groove design, allowing for multiple jaw positions and providing a firm grip. The undercut tongue and groove design prevent the jaws from slipping, ensuring a reliable hold even under high pressure.

Performance and Usability

When using the GLS-3 set, the first thing you'll notice is the comfortable grip. The handles are covered in a blue, plastic coating that is not only aesthetically pleasing but also comfortable to hold. Even after prolonged use, the handles don't dig into your palms or cause blisters, a common complaint with other brands.

The next thing that stands out is the ease of adjustment. The tongue and groove design allow for smooth and easy adjustment of the jaw width. This design ensures you can work on a wide range of tasks involving different sizes of nuts, bolts, and pipes.

The Channellock GLS-3 set excels in performance. The high-carbon steel jaws have a remarkable grip strength and are able to hold onto various materials without slipping. Whether you're tightening or loosening, the pliers hold firm, making your job much easier.


Channellock tools are renowned for their durability, and the GLS-3 set is no exception. The high-carbon C1080 steel construction combined with the patented PermaLock fastener ensures that these tools will last for years, even with heavy use. The rust-preventative coating provides an extra layer of protection, adding to the lifespan of the tools.


The three different sizes of pliers included in the GLS-3 set make it a versatile toolset. Whether you're working on a small, intricate task or a larger, heavy-duty job, one of the pliers in the set is likely to fit your needs. This versatility makes the set a great purchase for both beginners and experienced professionals.

Potential Drawbacks

Despite the numerous advantages of the GLS-3 set, there are a few potential drawbacks to consider.

First, while the plastic-coated handles offer a comfortable grip, they can sometimes feel a bit slippery, especially if your hands are sweaty or greasy. Some users may prefer handles with a more textured or rubberized grip.

Secondly, the pliers, particularly the larger ones, can be somewhat heavy and bulky. This might not be a problem for short tasks, but for longer jobs, the weight may cause fatigue.


The Channellock GLS-3 Tongue and Groove Plier Set proves to be an excellent addition to any toolbox. With its high-quality construction, impressive performance, and great versatility, it's a set that stands out in the crowded field of hand tools.

While it does have a few minor drawbacks, the overall benefits far outweigh them. Whether you're a professional tradesperson or a DIY enthusiast, the GLS-3 set is a worthwhile investment. With proper care, these tools can serve you for years, making every task a bit easier and more efficient.
