A mitre saw, also known as a "chop saw", is one of the most helpful and versatile tools a craftsman can own. It can help to simplify almost any wood crafting project, from framing to trim to cabinetry.

While the price of a mitre saw may at first seem high, it is an investment that you will never regret. The time and effort saved when using a chop saw will pay for itself in the first few hours alone. Like all power tools, there are a number of factors to consider when purchasing a quality saw.

Mitre saws are usually available in ten or twelve inch diameter blade models. Naturally, the larger saws cost a bit more but are far more practical when confronted with wider boards thanks to their higher maximum crosscut. Cutting a perfectly straight line, particularly an angled or beveled one, can be difficult when using a circular saw. With a twelve inch blade on your saw, even a 2x12 can be cut straight with ease. However, the larger saws are very heavy and bulky. If space and manoeuvrability are an issue, and you'll likely be dealing only with narrow lumber, a ten-inch model may be the best option.

Most mitre saws are "sliding" saws, meaning that blade and trigger mechanism are fixed on a rod. The blade can slide freely from front to back of the cutting deck, allowing it to cut through wider boards more easily. This is especially useful when making angled cuts. Also, the sliding motion feels more natural to someone accustomed to using circular saws.

An important factor to consider when purchasing a chop saw is the maximum mitre. This determines the amount that the saw blade mechanism will swivel, and the degree of cut that you can make on the board. While nearly all mitre saws will allow a forty-five degree cut, many can cut angles as steep as sixty degrees. Depending on the model, the mitre may be able to make steeper cuts on one side of the cutting deck than on the other. Locking mitre stops are a feature on practically every saw. These ensure that setting the saw to the most common cuts is quick and easy, and that the angle won't accidentally move as you work.

The amount of bevel that a chop saw can supply is also worth taking into account. Again, forty-five degrees is nearly a guarantee, but most saws will go well beyond that. Be aware that some of the smaller models will only pivot in one direction.

A plethora of options exist on modern mitre saws. Many are now available with optional laser guides to ensure your cut is precise. Most will also work on lightweight chop saw tables, making set up a breeze. Consider just what you want from your saw, as there are a number of extra features depending on the manufacturer and model.

With their versatility and ease of use, a quality mitre saw will quickly become the most important power tool you own.
