The Simplest Jigsaw Buying Guide
A jigsaw is an instrument used to cut curves and make complex patterns and designs in different types of materials. The other types of saws cannot perform certain cuts because of bigger blades and immobile limitations. Fortunately, the jigsaw can accurately cut difficult patterns since it has smaller blades and it can be transported from one position to another. It is a highly regarded tool for sawing creative designs in various materials. The tool is versatile as it can be a good option for making all types of cutting.
This tool is mainly for trimming wood. Nonetheless, it can also be used to cut other materials such as plastic, ceramics, paper and metal. The ability of the jigsaw to cut different materials depends on the type of blade.
Types of Cutting action
The most common cut done by this tool is a curve. The curve is a broad term as it also pertains to complex patterns and globular cuts. This competence allows the jigsaw to enhance your artistic and creative craft. A plunge cut is done by cutting in the middle of the materials used. Other saws would start at the edge. The saw can also be used for cutting in a straight manner. However, to make a perfectly straight cut, the person handling the saw must be skillful. Otherwise, the cut will be a little inclined. This tool has the ability of spinning around. This is to tilt the blade when making a bevel cut.
Types of Jigsaws
The majority of the saws have D-handle grips on top or barrel-grip handles. You may choose from the 3 power options.
The corded saws are powered by electricity. It has the ability to cut thick objects. The thickness varies depending on the unit and blades. One must be cautious in using this tool to avoid cutting the cord. Once the cord is cut, it can lead to an electrocution, the sudden death caused by an electric shock.
In this type, the tool is powered by batteries. It is less powerful than the corded ones. However, the advantage of this type is the portability. It may be heavier than the corded units.
Pneumatic saws are more advantageous because it is powered by the air. The air is being compressed by an air compressor. This is also the lightest among the three types. You can also prevent electrocution if you use this type in moist areas.
The unit for determining the power used is amps. The higher the amps, the powerful the jigsaw can be.The 3 to 4-amp saw can cut light objects, while the 5-amp or higher-amp saws can cut thick objects.
Standard Features of This Tool
This is very conducive as different types of materials need different speeds for sawing. The rule is to cut the light materials faster and the bulky materials slower.
This is the feature allowing you to cut the materials up to 45 degrees. Some units have easy-to-adjust regulators, where as some units need some tools to be adjusted.
Sometimes, the shadow cast directly on the portion you are going to cut. In this case, you need to switch on the LED guide light.
Some units have this useful feature. It is for gathering up the sawdust that is producedwhen cutting materials. This is to avoid the dust from accumulating in front of thejigsaw.
A sturdy case can protect the jigsaw when not in use. If you store the tool without a case, there is a tendency of being damaged.
You can buy the blades independently. For every type of cut, there is a corresponding blade to use. You can cut even the thickest material as long as you use the appropriate blade. You should be accustomed to use the suitable types of blades to cut the materials with accuracy.If you used the wrong blade, the blade may perform poorly or be broken.
Blades are made from different types of materials such as high-carbon steel, tungsten carbide, high-speed steel and bi-metal. It is advisable to use steel blades for the softwoods and the light metals. You must use the bi-metal blade for cutting heavy-duty materials, hardwoods and hard-to-cut materials. The tungsten carbide blade is compatible for cutting ceramics.
The measurement for the blade’s teeth is in teeth per inch. The quantity of the teeth can influence the material to be cut, the precision of every cut and the speed of the blade. The jigsaw with a lower count of teeth, approximately 6 to 20, is used in cutting soft materials like paper, cloth and wood. Softer materials can be easily cut by rough teeth. Hard materials such as ceramics and steel, needs a slow and more precise kind of cutting. The blade count must be about 14 to 36 teeth per inch.
There are two types of tooth set: the milled and the ground. The tooth set is responsible for the speed and coarseness of the blades. The milled tooth set is dull and usually used for faster and coarser cutting. The ground tooth set has sharp and fine-pointed teeth. This set has the ability to create finer cuts, although the speed decreases. The ground set tends to wear out faster than the milled set.
- For Easy-to-do tasks, you can use a cordless or a corded saw. The easy-to-do tasks include cutting 2 ¼ inches of softwood, 1 3/8 inches of hardwood and 3/16 inch of steel.
- For professional cuts, you can use a high-powered saw, either a corded or a pneumatic type. These cuts include cutting woods with thickness up to 3 3/8 inches.
The suitable saw must be inlined with your personal preference and purpose. Some features may be useful to some works, but may also be unnecessary to some cuts. For those people who will use the saw for simple tasks, it is advisable to purchase the cordless type. You need to consider these things in order to buy the most efficient jigsaw.
